  • Communications education and training: ethics and professionalism [Guest
    • Authors: Michelson; D.G.;Tong, W.;Shoop, B.L.;
      Pages: 16 - 17
      Abstract: Since antiquity, the difficulty of fulfilling multiple and sometimes conflicting moral obligations to different parties has been well recognized. By the 19th century, the emergence of engineering as a distinct profession was accompanied by a need to clarify the relationship between the self interest that practitioners of engineering have in advancing their careers and business interests, and their moral obligations to society, to their employers and/or clients, and to their profession.

  • Engineering ethics education: aligning practice and outcomes
    • Authors: Bairaktarova; D.;Woodcock, A.;
      Pages: 18 - 22
      Abstract: Analysis of the strengths and weaknesses of current efforts indicate that engineering programs lack consistent, accurate, and reliable methods of teaching professional ethics and measuring their outcomes. This raises two equally important issues: how we teach ethics and which student outcomes we are assessing. Engineering students are performing poorly on the Ethics part of the Fundamental Engineering exam, so clearly there is a misalignment between teaching practice and outcomes. Engineering ethics instruction is often focused on the instruction of moral judgment and assessing ethical awareness via students' responses to vignettes describing ethical dilemmas. In this study, we propose extending current practice from a focus on teaching moral reasoning to also considering students' ethical awareness and future behavior. We introduce motivational variables that engineering educators should consider when designing ethics curricula. The study findings suggest that these motivational factors may influence students' ethical awareness and predict their ethical behavior.

  • Integration of ethical training into undergraduate senior design projects
           on wireless communications
    • Authors: Arellano; W.;Guvenc, I.;Pala, N.;
      Pages: 24 - 29
      Abstract: Wireless communications engineers may face complex ethical dilemmas while designing products for consumers. At Florida International University's Electrical and Computer Engineering Department, we place great importance on training our students to address such ethical dilemmas, in alignment with ABET requirements. To this end, an ethical training framework is integrated into our two-semester senior design project course. In addition to the codes of ethics, our students use "The Theory Model" to make decisions based on ethical theories. For the solution of ethical dilemmas by means of ethical theories, they apply a modified version of the line drawing method. In this article we briefly explain the theories and methods that our students consider when facing ethical dilemmas. Then we present excerpts from four past senior design projects related to wireless communications. We also summarize the methodology the students use for identifying the best option to address ethical dilemmas.

  • The effect of a stand-alone ethics course in Chilean engineering students'
    • Authors: Murrugarra; R.I.;Wallace, W.A.;
      Pages: 30 - 34
      Abstract: Engineering ethics education is taking on increasing importance worldwide, but in Chile the percentage of universities that have a mandatory course concerning ethics is still small. Traditionally, Chilean universities with existing ethics courses teach them using a philosophical or theological perspective, limited to occidental theories, and usually from a Christian point of view. This article studies the impact of a new methodology and technique to teach ethics in Chile: case-based, non-normative, and with a critical-descriptive approach. An empirical study is conducted to assess the relative impact of an ethics class on students individual and inherent moral values and attitudes, and understand the factors that contribute to this impact. Results indicate that even though the importance of religion in Chile is decreasing, it is still a major source of students??? ethical principles and moral values. In addition, results suggest that a change in moral values develops when discussions among groups with different points of view occur.

  • Telecommunication engineering education (TEE): making the case for a new
           multidisciplinary undergraduate field of study
    • Authors: El-Bawab; T.S.;
      Pages: 35 - 39
      Abstract: Six years of sustained efforts to recognize telecommunication engineering (TE) as a distinct education discipline came to a successful conclusion on November 1, 2014, with ABET???s approval of its 2015-2016 Criteria for Electrical, Computer, Communications, Telecommunication(s) and Similarly Named Engineering Programs. This paper narrates the history of the Telecommunication Engineering Education (TEE) initiative and movement (2008–2014) which resulted in recognition of this field as a distinct engineering education discipline in the US and 28 other countries. We describe how the case for this recognition was made successfully, based on advances in network science and engineering. We discuss some aspects of the new ABET criteria, and how they relate to ongoing and anticipated changes in the arena of engineering education.

  • Underwater wireless communications and networks: theory and application:
           Part 1 [Guest Editorial]
    • Authors: Zhang; X.;Cui, J.-H.;Das, S.;Gerla, M.;Chitre, M.;
      Pages: 40 - 41
      Abstract: The Earth is a water planet, two-thirds of which is covered by water. With the rapid developments in technology, underwater communications has become a fast growing field, with broad applications in commercial and military water based systems. The need for underwater wireless communications exists in applications such as remote control in the off-shore oil industry, pollution monitoring in environmental systems, collection of scientific data from ocean-bottom stations, disaster detection and early warning, national security and defense (intrusion detection and underwater surveillance), as well as new resource discovery. Thus, the research of new underwater wireless communication techniques has played the most important role in the exploration of oceans and other aquatic environments. In contrast with terrestrial wireless radio communications, the communication channels in underwater wireless networks can be seriously affected by the marine environment, by noise, and by limited bandwidth and power resources, and by the harsh underwater ambient conditions. Hence, the underwater communication channel often exhibits severe attenuation, multipath effect, frequency dispersion, and constrained bandwidth and power resources, etc., which turn the underwater communication channel into one of the most complex and harsh wireless channels in nature. When facing these unique conditions in diverse underwater applications, many new challenges, which were not encountered in terrestrial wireless communications, are emerging in underwater acoustic, optical, and RF communications for future underwater wireless networks. Of these challenges, acoustic and optical are the most compelling, and somewhat complementary, owing to the potential for longer range and high bandwidth networked communications in sizeand power-constrained modems and unmanned systems.

  • Realizing underwater communication through magnetic induction
    • Authors: Akyildiz; I.F.;Wang, P.;Sun, Z.;
      Pages: 42 - 48
      Abstract: The majority of the work on underwater communication has mainly been based on acoustic communication. Acoustic communication faces many known problems, such as high propagation delays, very low data rates, and highly environment-dependent channel behavior. In this article, to address these shortcomings, magnetic induction is introduced as a possible communication paradigm for underwater applications. Accordingly, all research challenges in this regard are explained. Fundamentally different from the conventional underwater communication paradigm, which relies on EM, acoustic, or optical waves, the underwater MI communications rely on the time varying magnetic field to covey information between the transmitting and receiving parties. MI-based underwater communications exhibit several unique and promising features such as negligible signal propagation delay, predictable and constant channel behavior, sufficiently long communication range with high bandwidth, as well as silent and stealth underwater operations. To fully utilize the promising features of underwater MI-based communications, this article introduces the fundamentals of underwater MI communications, including the MI channel models, MI networking protocols design, and MI-based underwater localization.

  • Undersea laser communication with narrow beams
    • Authors: Fletcher; A.S.;Hamilton, S.A.;Moores, J.D.;
      Pages: 49 - 55
      Abstract: Laser sources enable highly efficient optical communications links due to their ability to be focused into very directive beam profiles. Recent atmospheric and space optical links have demonstrated robust laser communications links at high rate with techniques that are applicable to the undersea environment. These techniques contrast to the broad-angle beams utilized in most reported demonstrations of undersea optical communications, which have employed LED-based transmitters. While the scattering in natural waters will cause the beam to broaden, a narrowly directive transmitter can still significantly increase the optical power delivered to a remote undersea terminal. Using Monte Carlo analysis of the undersea scattering environment, we show the two main advantages of narrow-beam optical communication: increased power throughput and decreased temporal spread. Based on information theoretic arguments, gigabit-per-second class links can be achieved at 20 extinction lengths by utilizing pulse position modulation, single-photon-sensitive receivers, and modern forward error correction techniques.

  • Security and privacy in localization for underwater sensor networks
    • Authors: Li; H.;He, Y.;Cheng, X.;Zhu, H.;Sun, L.;
      Pages: 56 - 62
      Abstract: Underwater sensor networks are envisioned to enable a wide range of underwater applications such as pollution monitoring, offshore exploration, and oil/gas spill monitoring. Such applications require precise location information as otherwise the sensed data might be meaningless. On the other hand, security and privacy are critical issues as underwater sensor networks are typically deployed in harsh environments. Nevertheless, most underwater localization schemes are vulnerable to many attacks and suffer from potential privacy violations as they are designed for benign environments. However, a localization scheme that does not consider security and privacy could lead to serious consequences, especially in critical applications such as military monitoring. In this article, we discuss the security and privacy issues in underwater localization, and investigate the techniques that can provide security and preserve node privacy in underwater sensor networks.

  • Software-defined underwater acoustic networks: toward a high-rate
           real-time reconfigurable modem
    • Authors: Demirors; E.;Sklivanitis, G.;Melodia, T.;Batalama, S.N.;Pados, D.A.;
      Pages: 64 - 71
      Abstract: We review and discuss the challenges of adopting software-defined radio principles in underwater acoustic networks, and propose a software-defined acoustic modem prototype based on commercial off-the-shelf components. We first review current SDR-based architectures for underwater acoustic communications. Then we describe the architecture of a new software-defined acoustic modem prototype, and provide performance evaluation results in both indoor (water tank) and outdoor (lake) environments. We present three experimental testbed scenarios that demonstrate the real-time reconfigurable capabilities of the proposed prototype and show that it exhibits favorable characteristics toward spectrally efficient cognitive underwater networks, and high data rate underwater acoustic links. Finally, we discuss open research challenges for the implementation of next-generation software-defined underwater acoustic networks.

  • Routing protocols for underwater wireless sensor networks
    • Authors: Han; G.;Jiang, J.;Bao, N.;Wan, L.;Guizani, M.;
      Pages: 72 - 78
      Abstract: Recently, underwater wireless sensor networks (UWSNs) have emerged as a promising networking technique for various underwater applications. An energy efficient routing protocol plays a vital role in data transmission and practical applications. However, due to the specific characteristics of UWSNs, such as dynamic structure, narrow bandwidth, rapid energy consumption, and high latency, it is difficult to build routing protocols for UWSNs. In this article we focus on surveying existing routing protocols in UWSNs. First, we classify existing routing protocols into two categories based on a route decision maker. Then the performance of existing routing protocols is compared in detail. Furthermore, future research issues of routing protocols in UWSNs are carefully analyzed.

  • Turbo equalization for single-carrier underwater acoustic communications
    • Authors: Zheng; Y.R.;Wu, J.;Xiao, C.;
      Pages: 79 - 87
      Abstract: Recent research in underwater acoustic communications has taken advantage of MIMO technologies to achieve reliable communication with 10–100 times increase of data rate in comparison to traditional systems. The powerful turbo equalization and FEC coding techniques enable both single-carrier modulation and OFDM systems to combat triply selective UWA channels. This article reviews the time-domain and frequency-domain turbo equalizer schemes for MIMO SCM systems. Low-complexity techniques are presented with both turbo linear equalizers and turbo soft decision feedback equalizers in both the time and frequency domains. Although results are shown specifically for UWA channels, these turbo equalizer techniques are also suitable for terrestrial RF communication systems.

  • Structured sparse methods for active ocean observation systems with
           communication constraints
    • Authors: Mitra; U.;Choudhary, S.;Hover, F.;Hummel, R.;Kumar, N.;Naryanan, S.;Stojanovic, M.;Sukhatme, G.;
      Pages: 88 - 96
      Abstract: Actuated sensor networks enabled by underwater acoustic communications can be efficiently used to sense over large marine expanses that are typically challenged by a paucity of resources (energy, communication bandwidth, number of sensor nodes). Many marine phenomena of interest admit sparse representations, which, coupled with actuation and cooperation, can compensate for being data starved. Herein, new methods of field reconstruction, target tracking, and exploration-exploitation are provided, which adopt sparse approximation, compressed sensing, and matrix completion algorithms. The needed underlying structure (sparsity/low-rank) is quite general. The unique constraints posed by underwater acoustic communications and vehicle kinematics are explicitly considered. Results show that solutions can be practically implemented, even over large ocean spaces.

  • Underwater sensor networks: a new challenge for opportunistic routing
    • Authors: Darehshoorzadeh; A.;Boukerche, A.;
      Pages: 98 - 107
      Abstract: Opportunistic routing (OR) is a promising paradigm that selects the next-hop forwarder on the fly. OR has gained a lot of attention from the research community for its ability to increase the performance of wireless networks. In OR a potential group of nodes (candidates) is selected to help as the next-hop forwarder. Each candidate that receives the packet can continue forwarding the packet. In OR, by using a dynamic relay node to forward the packet, the transmission reliability and network throughput are increased. Underwater sensor networks (UWSNs) collect data from the environment and transfer them to the sonobuoys on the surface to send them to a center for further processing. Because of the acoustic channels common to UWSNs, they have low bandwidth, high error probability, and longer propagation delay compared to radio channels. These properties of UWSNs make them good potential candidates for using OR concepts to deliver packets to the destination. This article reviews and compares different OR protocols proposed for UWSNs. We classify the existing approaches in different categories, discuss representative examples for each class of protocols, and uncover the requirements considered by the different protocols, as well as the design requirements and limitations under which they operate. Finally, we discuss potential future research directions for UWSNs using the OR paradigm.

  • Software defined wireless networks (SDWN): Part 1 [Guest Editorial]
    • Authors: Hu; H.;Chen, H.-H.;Mueller, P.;RoHu, R.Q.;Rui, Y.;
      Pages: 108 - 109
      Abstract: The growing popularity of smart phones, tablet computers and mobile cloud services places an increasing demand for dynamic services from wireless networks. This demand creates new requirements for the network architecture, such as flexibility in management and configuration, adaptability and vendor-independence. To meet these requirements, software defined wireless network (SDWN) has been proposed as a cost-effective solution. SDWN decouples the data plane from the control plane, enabling direct programmability of network controls and an abstraction of the underlying infrastructure for wireless applications. With SDWN, we can create a service delivery platform that is adaptable to the users??? varying demands. However, issues such as supporting a large number of subscribers, frequent mobility, fine-grained measurement and control, and real-time adaptation need to be addressed by future SDWN architectures. In this Feature Topic, we provide an overview of the latest major developments and progresses in SDWN.

           wireless networks
    • Authors: Zhou; Q.;Wang, C.-X.;McLaughlin, S.;Zhou, X.;
      Pages: 110 - 117
      Abstract: Future networks will be defined by software. In contrast to a wired network, the software defined wireless network (SDWN) experiences more challenges due to the fast-changing wireless channel environment. This article focuses on the state-of-the-art of SDWN architecture, including control plane virtualization strategies and semantic ontology for network resource description. In addition, a novel SDWN architecture with resource description function is proposed, along with two ontologies for the resource description of the latest wireless network. Future research directions for SDWN, control strategy design, and resource description are also addressed.

  • When ICN meets C-RAN for HetNets: an SDN approach
    • Authors: Yang; C.;Chen, Z.;Xia, B.;Wang, J.;
      Pages: 118 - 125
      Abstract: With ever growing mobile Internet and the explosion of its applications, users are experiencing abundant services from different content providers via different network service providers in the heterogeneous network. The information-centric network (ICN) advocates getting rid of the current host-centric network protocol because information dissemination rather than end-to-end communication contributes to the majority of today's network traffic. Furthermore, it is better for network entities to converge as a whole in order to take advantage of open, scalable, and smart traffic transmission. The cloud radio access network is one of the emerging architecture evolutions on the wireless side for easier infrastructure deployment and network management. Therefore, when the information-centric network meets the C-RAN in the Het-Net, it is worthwhile and consequential to integrate ICN protocol with C-RAN architecture to achieve more efficient communication and information management. Moreover, SDN has been recognized as another promising architecture evolution to achieve the flexibility and reconfigurability of dense HetNets; its inherent advantage lies in global uniform control of the wired network. Thus, any of ICN, C-RAN and SDN is the complementary to the others. In this article, we contribute to a fresh proposal for and elaboration of the integration of the ICN, CRAN, and SDN for the HetNet to achieve a win-win situation. The vision of the proposed system is demonstrated, followed by the advantages and challenges. We further present a hybrid system in a large-scale wireless heterogeneous campus network.

  • Software defined mobile networks: concept, survey, and research directions
    • Authors: Chen; T.;Matinmikko, M.;Chen, X.;Zhou, X.;Ahokangas, P.;
      Pages: 126 - 133
      Abstract: This article provides a brief overview on the current development of software-defined mobile networks (SDMNs). Software defined networking is seen as a promising technology to manage the complexity in communication networks. The need for SDMN comes from the complexity of network management in 5G mobile networks and beyond, driven by increasing mobile traffic demand, heterogeneous wireless environments, and diverse service requirements. The need is strong to introduce new radio network architecture by taking advantage of software oriented design, the separation of the data and control planes, and network virtualization to manage complexity and offer flexibility in 5G networks. Clearly, software oriented design in mobile networks will be fundamentally different from SDN for the Internet, because mobile networks deal with the wireless access problem in complex radio environments, while the Internet mainly addresses the packet forwarding problem. Specific requirements in mobile networks shape the development of SDMN. In this article we present the needs and requirements of SDMN, with particular focus on the software-defined design for radio access networks. We analyze the fundamental problems in radio access networks that call for SDN design and present an SDMN concept. We give a brief overview on current solutions for SDMN and standardization activities. We argue that although SDN design is currently focusing on mobile core networks, extending SDN to radio access networks would naturally be the next step. We identify several research directions on SDN for radio access networks and expect more fundamental studies to release the full potential of software-defined 5G networks.

  • Service provider competition and cooperation in cloud-based software
           defined wireless networks
    • Authors: Ding; J.;Yu, R.;Zhang, Y.;Gjessing, S.;Tsang, D.H.K.;
      Pages: 134 - 140
      Abstract: Software-defined wireless networking (SDWN) is an emerging paradigm in the era of the Internet of Things. In cloud-based SDWNs, resource management is seperated from the geo-distributed cloud, forming a virtual network topology in the control plane. Thus, a centralized software program is able to control and program the behavior of the entire network. In this article, we focus on resource management in cloud-based SDWNs, and discuss the competition and cooperation between cloud service providers. We present a Nash bargaining game approach to process the resource trading activity among cloud service providers in cloud-based SDWNs. Utility functions have been specifically considered to incorporate operation cost and resource utilization. Illustrative results indicate that cooperation is able to generate more benefits than competition. Moreover, resource sharing among cloud service providers has great significance in efficiently utilizing limited resources and improving quality of service.

  • An intelligent SDN framework for 5G heterogeneous networks
    • Authors: Sun; S.;Gong, L.;Rong, B.;Lu, K.;
      Pages: 142 - 147
      Abstract: In fifth-generation (5G) mobile networks, a major challenge is to effectively improve system capacity and meet dynamic service demands. One promising technology to solve this problem is heterogeneous networks (HetNets), which involve a large number of densified low power nodes (LPNs). This article proposes a software defined network (SDN) based intelligent model that can efficiently manage the heterogeneous infrastructure and resources. In particular, we first review the latest SDN standards and discuss the possible extensions. We then discuss the advantages of SDN in meeting the dynamic nature of services and requirements in 5G HetNets. Finally, we develop a variety of schemes to improve traffic control, subscriber management, and resource allocation. Performance analysis shows that our proposed system is reliable, scalable, and implementable.

  • Green communications and computing networks [Series Editorial]
    • Authors: Wu; J.;Thompson, J.;Zhang, H.;Kilper, D.C.;
      Pages: 148 - 149
      Abstract: The concept of green information and communications technologies (ICT) is relevant to both environmental sustainability and ICT. Green ICT is an interdisciplinary field relevant to a number of areas and topics, such as information systems, computer science and technologies, communications and networking, power and energy systems, electronics, environmental and civil engineering, industrial engineering and project management, social sciences, and so on. The green ICT could be considered a coined-term from two highly overlapped terms, green communications [1] and green computing [2]. Basically, two mainstream ideas may be addressed in green ICT, i.e., greening ICT and ICT for green objectives. Even if the field of green ICT has been receiving more and more attentions in research communities as well as industrial, governmental, and international organizations [1???5], more and more technical investigations and applications are still expected due to the relevant long term concerns and challenges. In early 2015, the IEEE Technical Committee on Green Communications and Computing (TCGCC), IEEE Research Project on Vision for Green ICT Standardizations, and IEEE Technical SubCommittee on Big Data (TSCBD) jointly initialized the efforts of the first IEEE International Workshop on Green Standardization and Industry Issues for ICT and Relevant Technologies (GSICT), which will be held in conjunction with the 2015 IEEE Global Communications Conference (Globe-com 2015), and the motivation of the efforts is to promote more relevant activities, especially standardization, towards green objectives in industry. Surely, the IEEE Series on Green Communications and Computing Networks can expect more submissions on the relevant industry issues and standardization activities in the future.

  • Green energy optimization in energy harvesting wireless sensor networks
    • Authors: Zheng; J.;Cai, Y.;Shen, X.;Zheng, Z.;Yang, W.;
      Pages: 150 - 157
      Abstract: This article studies the sensor activation control for the optimization of green energy utilization in an EH-WSN, where both energy generation and target distribution exhibit temporal and spatial diversities. Decentralized operation is considered for the green energy optimization in the EH-WSN. The optimization is achieved in two dimensions: dynamic (activation) mode adaptation in the temporal dimension and energy balancing in the spatial dimension. Due to the interactions among autonomous distributed sensors, game theory is applied to the local information based decentralized optimization for the spatial energy balancing problem. In addition, reinforcement learning techniques are proposed to address the temporal mode adaptation in the dynamic and unknown environment. Simulation results are provided to demonstrate the effectiveness of the proposed approaches.

  • On balancing energy efficiency for network operators and mobile users in
           dynamic planning
    • Authors: Ismail; M.;Kashef, M.;Serpedin, E.;Qaraqe, K.;
      Pages: 158 - 165
      Abstract: The high energy consumption of network operators and mobile users has raised environmental, financial, and quality-of-experience concerns. These concerns have renewed the research efforts in developing green communication strategies for energy efficient wireless network operation. Network operators employ dynamic planning to save energy at low call traffic load by switching off some of their base stations (BSs), and mobile users are served by the remaining active BSs. The existing research investigates energy efficiency of dynamic planning approaches only from the network operator perspective. Dynamic planning, if not carefully designed, can lead to higher energy consumption for the mobile users in the uplink, which in turn degrades the uplink service quality due to mobile terminals' battery depletion. In this article we propose a dynamic planning framework with balanced energy efficiency that accounts for the energy consumption of the mobile users in the uplink as well as that of the network operators in the downlink. We discuss the associated challenges and implementation issues. A dynamic planning approach based on a multi-time scale decision process is proposed to achieve the balanced energy efficiency framework. Numerical results demonstrate the improved energy efficiency performance for the uplink mobile users as compared with the traditional dynamic planning approach.

  • Post-peak ICT: graceful degradation for communication networks in an

      Pages: 166 - 174
      Abstract: In recent years, rising energy prices and increasing environmental concerns have boosted research in the so called green ICT and green networking research tracks, aimed at improving the energy efficiency of communications while still offering maximal functionality. In this article we explore a future scenario in which low power networking is no longer optional, but instead becomes a necessity due to fluctuating energy availability. The contribution of this work is twofold. First, we argue why a so called post-peak future scenario, in which we can no longer rely on fossil fuels as our main resource for electricity production, is not unlikely, and what it might entail. Second, we explore the consequences of such a scenario for ICT: How well can current and future infrastructures cope with temporary energy limitations? As an illustration, we present a case study showing the impact of reduced energy availability on a wireless access network.

  • A survey of green scheduling schemes for homogeneous and heterogeneous
           cellular networks
    • Authors: Yang; T.;Heliot, F.;Foh, C.H.;
      Pages: 175 - 181
      Abstract: Energy efficiency is becoming an important feature for designing the next generation of communication networks, as are the multiplication of access points and the reduction of their coverage area. In this article we survey the latest development in energy-efficient scheduling, a.k.a. green scheduling, for both classic and heterogeneous cellular networks. We first introduce the main system model and framework that are considered in most of the existing green scheduling works. We then describe the main contributions on green scheduling as well as summarize their key findings. For instance, green scheduling schemes have demonstrated that they can significantly reduce transmit power and improve the energy efficiency of cellular systems. We also provide a performance analysis of some of the existing schemes in order to highlight some of the challenges that need to be addressed to make green scheduling more effective in heterogeneous networks. Indeed, the coordination between tiers and the rate fairness between the users of different tiers are important issues that have not yet been addressed. In addition, most existing designs exhibit a computational complexity that is too high for being deployed in a real system.

  • Assessing network energy consumption of mobile applications
    • Authors: Chan; C.A.;Li, W.;Bian, S.;I, C.-L.;Gygax, A.F.;Leckie, C.;Yan, M.;Hinton, K.;
      Pages: 182 - 191
      Abstract: Continuous growth in the energy consumption of mobile networks has become a major concern for mobile carriers. Since current mobile networks are dominated by mobile data traffic generated by over-the-top mobile applications, it is crucial for mobile carriers to understand how much network energy is used to deliver these applications. Here, we use real network and application measurements to comprehensively analyze the energy consumption of 12 common mobile applications by breaking down their total energy consumption into data and signaling energy components. The results provide insights into the different proportions of data and signaling energy (due to LTE signaling) for different mobile applications. They show that the energy consumption of a mobile application can vary at different base station cell sites due to different ratios of throughput to physical resource block utilization. We estimate the total monthly energy consumption of all 4G users of a major mobile carrier using conventional mobile services, such as voice and the short messaging service, and two over-the-top applications, i.e. a popular instant messaging application in China and an online video application. The results show that signaling energy consumption may become a major concern for mobile carriers, and that this issue will be exacerbated as the usage of over-the-top applications continues to grow. Energy assessment of mobile applications provides valuable information to enable mobile carriers to improve the energy efficiency of their networks. An energy assessment tool that enables real-time network and service energy monitoring will also assist in developing energy-efficient network policies for diverse applications with different energy consumption profiles. Furthermore, given our signaling energy consumption findings for over-the-top applications, there may be benefits for mobile operators to introduce a surcharge for signaling traffic to mitigate the high signaling energy consumption of - ome over-the-top mobile applications.

  • Toward green data centers as an interruptible load for grid stabilization
           in Singapore
    • Authors: Xia; W.;Wen, Y.;Toh, K.-C.;Wong, Y.-W.;
      Pages: 192 - 198
      Abstract: For sustainability and environmental friendliness, renewable energy (RE) and distributed generation (DG), for example, photovoltaic, are being integrated in electrical systems in many countries. RE and DG, however, can be unstable for the power grid. As the power grid integrates an increasing amount of RE and DG, we present technical solutions along with an economic incentive model to enable data centers to serve as a novel "interruptible" load (i.e. a power load that can be scaled down temporally) to stabilize the power grid. We propose a novel real-time power analytics framework called embedded software as sensors, where software hooks are embedded into a range of data center subsystems, from chip to system to application level, to monitor ICT activities and power usage in a fine grained, real-time manner. Data from these virtual sensors are then mined to construct energy consumption models, which in turn are used to develop optimal algorithms for energy aware operation of computing, power distribution, and cooling systems in the data center. This holistic monitoring and optimization framework can reduce the overall power consumption of the data center, and furthermore enables time shifting of workloads in the data center in response to power fluctuations arising from the integration of RE and DG to the power grid.

  • Green sensing and access: energy-throughput trade-offs in cognitive
    • Authors: Hossein Shokri-Ghadikolaei; H.;Glaropoulos, I.;Fodor, V.;Fischione, C.;Ephremides, A.;
      Pages: 199 - 207
      Abstract: Limited spectrum resources and the dramatic growth of high data rate applications have motivated opportunistic spectrum access exploiting the promising concept of cognitive networks. Although this concept has emerged primarily to enhance spectrum utilization and to allow the coexistence of heterogeneous network technologies, the importance of energy consumption imposes additional challenges, because energy consumption and communication performance can be at odds. In this article the approaches for energy efficient spectrum sensing and spectrum handoff, fundamental building blocks of cognitive networks, are investigated. The trade-offs between energy consumption and throughput, under local as well as under cooperative sensing, are characterized. We also discuss the additional factors that need to be investigated to achieve energy efficient cognitive operation under various application requirements.
