  • Scenarios for 5G mobile and wireless communications: the vision of the
           METIS project
    • Authors: Osseiran; A.;Boccardi, F.;Braun, V.;Kusume, K.;Marsch, P.;Maternia, M.;Queseth, O.;Schellmann, M.;Schotten, H.;Taoka, H.;Tullberg, H.;Uusitalo, M.A.;Timus, B.;Fallgren, M.;
      Pages: 26 - 35
      Abstract: METIS is the EU flagship 5G project with the objective of laying the foundation for 5G systems and building consensus prior to standardization. The METIS overall approach toward 5G builds on the evolution of existing technologies complemented by new radio concepts that are designed to meet the new and challenging requirements of use cases today''s radio access networks cannot support. The integration of these new radio concepts, such as massive MIMO, ultra dense networks, moving networks, and device-to-device, ultra reliable, and massive machine communications, will allow 5G to support the expected increase in mobile data volume while broadening the range of application domains that mobile communications can support beyond 2020. In this article, we describe the scenarios identified for the purpose of driving the 5G research direction. Furthermore, we give initial directions for the technology components (e.g., link level components, multinode/multiantenna, multi-RAT, and multi-layer networks and spectrum handling) that will allow the fulfillment of the requirements of the identified 5G scenarios.

  • The requirements, challenges, and technologies for 5G of terrestrial
           mobile telecommunication
    • Authors: Chen; S.;Zhao, J.;
      Pages: 36 - 43
      Abstract: In this article, we summarize the 5G mobile communication requirements and challenges. First, essential requirements for 5G are pointed out, including higher traffic volume, indoor or hotspot traffic, and spectrum, energy, and cost efficiency. Along with these changes of requirements, we present a potential step change for the evolution toward 5G, which shows that macro-local coexisting and coordinating paths will replace one macro-dominated path as in 4G and before. We hereafter discuss emerging technologies for 5G within international mobile telecommunications. Challenges and directions in hardware, including integrated circuits and passive components, are also discussed. Finally, a whole picture for the evolution to 5G is predicted and presented.

  • The role of small cells, coordinated multipoint, and massive MIMO in 5G
    • Authors: Jungnickel; V.;Manolakis, K.;Zirwas, W.;Panzner, B.;Braun, V.;Lossow, M.;Sternad, M.;Apelfrojd, R.;Svensson, T.;
      Pages: 44 - 51
      Abstract: 5G will have to support a multitude of new applications with a wide variety of requirements, including higher peak and user data rates, reduced latency, enhanced indoor coverage, increased number of devices, and so on. The expected traffic growth in 10 or more years from now can be satisfied by the combined use of more spectrum, higher spectral efficiency, and densification of cells. The focus of the present article is on advanced techniques for higher spectral efficiency and improved coverage for cell edge users. We propose a smart combination of small cells, joint transmission coordinated multipoint (JT CoMP), and massive MIMO to enhance the spectral efficiency with affordable complexity. We review recent achievements in the transition from theoretical to practical concepts and note future research directions. We show in measurements with macro-plus-smallcell scenarios that spectral efficiency can be improved by flexible clustering and efficient user selection, and that adaptive feedback compression is beneficial to reduce the overhead significantly. Moreover, we show in measurements that fast feedback reporting combined with advanced channel prediction are able to mitigate the impairment effects of JT CoMP.

  • Advanced interference management for 5G cellular networks
    • Authors: Nam; W.;Bai, D.;Lee, J.;Kang, I.;
      Pages: 52 - 60
      Abstract: As 4G cellular systems densify their cell deployment, co-channel interference becomes a major source of obstacles to cell throughput improvement. In addition, cell edge users suffer more from co-channel interference, which may govern end users'' experiences. Although some network-side solutions for co-channel interference management have been introduced in current 4G standards, it turns out that most of those solutions yield only meager gains in realistic cellular environments. In this article, we pay attention to recent advances in the network information theory and discuss the benefits of UE-side approaches. Based on this understanding, we provide our vision on advanced interference management for 5G cellular systems: network-side interference management needs to be complemented by UE-side interference management to realize true factor-one resource reuse. We also discuss practical challenges to deploy advanced interference management and their implications on 5G system design. Prospective gains of advanced interference management are demonstrated, and it is shown that the benefits of advanced receivers can be well exploited if 5G cellular networks employ elaborated joint scheduling.

  • Cooperative distributed optimization for the hyper-dense small cell
    • Authors: Xu; J.;Wang, J.;Zhu, Y.;Yang, Y.;Zheng, X.;Wang, S.;Liu, L.;Horneman, K.;Teng, Y.;
      Pages: 61 - 67
      Abstract: The fifth generation mobile networks will be developed to improve area spectral and energy efficiency, and provide uniform user experience. Hyper-dense small cell deployment can move devices closer to the wireless network and satisfy 5G system requirements. The main challenge of this network deployment results from the random deployment, dynamic on-off, flexible connection to cellular core networks, and flat system architecture of 5G systems. Therefore, conventional network planning and radio resource management, which depend on a central control node, cannot be applied to small cell networks. In this article some cooperative distributed radio resource management algorithms for time synchronization, carrier selection, and power control are discussed for hyper-dense small cell deployment.

  • Cloud technologies for flexible 5G radio access networks
    • Authors: Rost; P.;Bernardos, C.J.;Domenico, A.D.;Girolamo, M.D.;Lalam, M.;Maeder, A.;Sabella, D.;W??bben, D.;
      Pages: 68 - 76
      Abstract: The evolution toward 5G mobile networks will be characterized by an increasing number of wireless devices, increasing device and service complexity, and the requirement to access mobile services ubiquitously. Two key enablers will allow the realization of the vision of 5G: very dense deployments and centralized processing. This article discusses the challenges and requirements in the design of 5G mobile networks based on these two key enablers. It discusses how cloud technologies and flexible functionality assignment in radio access networks enable network densification and centralized operation of the radio access network over heterogeneous backhaul networks. The article describes the fundamental concepts, shows how to evolve the 3GPP LTE architecture, and outlines the expected benefits.

  • Accelerating 5G QoE via public-private spectrum sharing
    • Authors: Mitola, J; III;Guerci, J.;Reed, J.;Yao, Y.-D.;Chen, Y.;Clancy, T.C.;Dwyer, J.;Li, H.;Man, H.;McGwier, R.;Guo, Y.;
      Pages: 77 - 85
      Abstract: Fifth generation wireless systems (5G) must achieve high user Quality of Experience (QoE) in order to compete for market share. Each candidate 5G wireless radio frequency (RF) band offers advantages such as longer range or higher data rate than 2G, 3G, and 4G, but no single band or air interface standard by itself fully achieves ubiquitous levels of QoE for the complete range of wireless access devices. Spectrum clearing cannot keep pace with user demand, so public-private spectrum sharing is emerging as an affordable, near-term method of increasing radio access network (RAN) capacities for content delivery. This paper presents a fresh look at QoE; spectrum scarcity; public uses that underutilize candidate 5G radio frequency (RF) spectrum; and emerging public-private radio interference management frameworks that enable near-term spectrum sharing, with positive consequences for 5G price, performance, and total user QoE.

  • Device-to-device communication in 5G cellular networks: challenges,
           solutions, and future directions
    • Authors: Tehrani; M.N.;Uysal, M.;Yanikomeroglu, H.;
      Pages: 86 - 92
      Abstract: In a conventional cellular system, devices are not allowed to directly communicate with each other in the licensed cellular bandwidth and all communications take place through the base stations. In this article, we envision a two-tier cellular network that involves a macrocell tier (i.e., BS-to-device communications) and a device tier (i.e., device-to-device communications). Device terminal relaying makes it possible for devices in a network to function as transmission relays for each other and realize a massive ad hoc mesh network. This is obviously a dramatic departure from the conventional cellular architecture and brings unique technical challenges. In such a two-tier cellular system, since the user data is routed through other users'' devices, security must be maintained for privacy. To ensure minimal impact on the performance of existing macrocell BSs, the two-tier network needs to be designed with smart interference management strategies and appropriate resource allocation schemes. Furthermore, novel pricing models should be designed to tempt devices to participate in this type of communication. Our article provides an overview of these major challenges in two-tier networks and proposes some pricing schemes for different types of device relaying.

  • An energy efficient and spectrum efficient wireless heterogeneous network
           framework for 5G systems
    • Authors: Hu; R.Q.;Qian, Y.;
      Pages: 94 - 101
      Abstract: In this article we explore a system framework of cooperative green heterogeneous networks for 5G wireless communication systems. We first survey the state-of-the-art on spectrum efficiency (SE), energy efficiency (EE), and quality of service (QoS) based mobile association, multi-layer interference management and power control, network wide cooperation and dynamic resource allocation for heterogeneous wireless networks. We also present the system framework of cooperative green heterogeneous networks, which aims at balancing and optimizing SE, EE, and QoS in heterogeneous wireless networks. We discuss the design principles and show some preliminary performance results on the tradeoffs among SE, EE, and QoS. Finally, we identify the technical challenges that remain in the cooperative green heterogeneous network design. The presented wireless system framework is expected to advance the understandings of the critical technical issues toward energy and spectrum efficient 5G wireless communication systems.

Air traffic management modernization is required to meet the needs sustainable air traffic growth in Europe, the United States, and worldwide are posing. A key enabler for this modernization process is the introduction of improved communications, navigation, and surveillance technologies. In this article, new developments in aeronautical communications for air traffic management are presented, with special focus on the air/ground communications technology L-band Digital Aeronautical Communications System (LDACS). The most promising LDACS technology candidate, LDACS1, is described in detail, and possible extensions toward navigation and surveillance are discussed. With these extensions, LDACS1 is well placed to become the first integrated communications, navigation, and surveillance technology for civil aviation. Utilizing a common ground infrastructure, such an integrated approach simplifies deployment and reduces costs for both deployment and maintenance.

      Abstract: Air traffic is continuously increasing worldwide, with both manned and unmanned aircraft looking to coexist in the same airspace in the future. Next generation air traffic management systems are crucial in successfully handling this growth and improving the safety of billions of future passengers. The Automatic Dependent Surveillance Broadcast (ADS-B) system is a core part of this future. Unlike traditional radar systems, this technology empowers aircraft to automatically broadcast their locations and intents, providing enhanced situational awareness. This article discusses important issues with the current state of ADS-B as it is being rolled out. We report from our OpenSky sensor network in Central Europe, which is able to capture about 30 percent of the European commercial air traffic. We analyze the 1090 MHz communication channel to understand the current state and its behavior under the increasing traffic load. Furthermore, the article considers important security challenges faced by ADS-B. Our insights are intended to help identify open research issues, furthering new interest and developments in this field.

      Abstract: Networks of micro aerial vehicles (MAVs) equipped with various sensors are increasingly used for civil applications, such as monitoring, surveillance, and disaster management. In this article, we discuss the communication requirements raised by applications in MAV networks. We propose a novel system representation that can be used to specify different application demands. To this end, we extract key functionalities expected in an MAV network. We map these functionalities into building blocks to characterize the expected communication needs. Based on insights from our own and related real-world experiments, we discuss the capabilities of existing communications technologies and their limitations to implement the proposed building blocks. Our findings indicate that while certain requirements of MAV applications are met with available technologies, further research and development is needed to address the scalability, heterogeneity, safety, quality of service, and security aspects of multi- MAV systems.

      Abstract: Airborne tactical networks (ATNs) have provided protected air-to-air communications for military aircraft for several decades. To support emerging and future warfighter needs, the next generation of systems will require significant improvements to provide higher capacity, longer range, greater flexibility, and increased interoperability. Governed by domain characteristics such as long transmission ranges, low-to-medium data rates, latency constraints, and link protection needs, the air tactical domain poses several unique requirements on link and network design. Developing next-generation ATNs requires an understanding of the airborne tactical domain, including the design constraints and challenges at various layers of the network stack. In this article, we provide an overview of the unique domain characteristics of ATNs and highlight the key design challenges and research areas associated with the physical, link, and network layers.

  • Monitoring and troubleshooting multi-domain networks using measurement

    • Authors: Calyam; P.;Dovrolis, C.;J??rgenson, L.;Kettimuthu, R.;Tierney, B.;Zurawski, J.;
      Pages: 146 - 147
      Abstract: In both the scientific and corporate worlds, users, resources, and data are often physically distributed, making networks increasingly important for all operations. Enormous progress has been made in increasing the capacity and accessibility of networking infrastructures, which in turn has fostered wider-adoption of cloud and grid environments. Unfortunately, these advances have not directly translated into improved performance for all applications and users; instead, network performance problems become even more subtle and detrimental as the capacity of the network increases, and troubleshooting them on multidomain network paths is highly challenging. These problems may be as benign as congestion from other network users, or as serious as packet loss caused by one or more intermediate domain infrastructure and architectural flaws.

  • mPlane: an intelligent measurement plane for the internet
    • Authors: Trammell; B.;Casas, P.;Rossi, D.;B??r, A.;Houidi, Z.B.;Leontiadis, I.;Szemethy, T.;Mellia, M.;
      Pages: 148 - 156
      Abstract: The Internet''s universality is based on its decentralization and diversity. However, its distributed nature leads to operational brittleness and difficulty in identifying the root causes of performance and availability issues, especially when the involved systems span multiple administrative domains. The first step to address this fragmentation is coordinated measurement: we propose to complement the current Internet''s data and control planes with a measurement plane, or mPlane for short. mPlane''s distributed measurement infrastructure collects and analyzes traffic measurements at a wide variety of scales to monitor the network status. Its architecture is centered on a flexible control interface, allowing the incorporation of existing measurement tools through lightweight mPlane proxy components, and offering dynamic support for new capabilities. A focus on automated, iterative measurement makes the platform well-suited to troubleshooting support. This is supported by a reasoning system, which applies machine learning algorithms to learn from success and failure in drilling down to the root cause of a problem. This article describes the mPlane architecture and shows its applicability to several distributed measurement problems involving content delivery networks and Internet service roviders. A first case study presents the tracking and iterative analysis of cache selection policies in Akamai, while a second example focuses on the cooperation between Internet service providers and content delivery networks to better orchestrate their traffic engineering decisions and jointly improve their performance.

  • Enabling persistent queries for cross-aggregate performance monitoring
    • Authors: Mandal; A.;Baldin, I.;Xin, Y.;Ruth, P.;Heerman, C.;
      Pages: 157 - 164
      Abstract: It is essential for distributed, data-intensive applications to monitor the performance of the underlying network, storage, and computational resources. Increasingly, distributed applications need performance information from multiple aggregates, and tools need to make real-time steering decisions based on the performance feedback. With increasing scale and complexity, the volume and velocity of monitoring data is increasing, posing scalability challenges. In this work, we have developed a persistent query agent (PQA) that provides real-time application and network performance feedback to clients/ applications, thereby enabling dynamic adaptations. The PQA enables federated performance monitoring by interacting with multiple aggregates and performance monitoring sources. Using a publish-subscribe framework, it sends triggers asynchronously to applications/clients when relevant performance events occur. The applications/clients register their events of interest using declarative queries and get notified by the PQA. The PQA leverages a complex event processing (CEP) framework for managing and executing the queries expressed in a standard SQL-like query language. Instead of saving all monitoring data for future analysis, PQA observes performance event streams in real time, and runs continuous queries over streams of monitoring events. In this work, we present the design and architecture of the PQA, and describe some relevant use cases.

  • Building a standard measurement platform

      Pages: 165 - 173
      Abstract: Network management is achieved through a large number of disparate solutions for different technologies and parts of the end-to-end network. Gaining an overall view, and especially predicting the impact on a service user, is difficult. Recently, a number of proprietary platforms have emerged to conduct end-to-end testing from user premises; however, these are limited in scale, interoperability, and the ability to compare like-for-like results. In this article we show that these platforms share similar architectures and can benefit from the standardization of key interfaces, test definitions, information model, and protocols. We take the SamKnows platform as a use case and propose an evolution from its current proprietary protocols to standardized protocols and tests. In particular, we propose to use extensions of the IETF''s IPFIX and NETCONF/YANG in the platform. Standardization will allow measurement capabilities to be included on many more network elements and user devices, providing a much more comprehensive view of user experience and enabling problems and performance bottlenecks to be identified and addressed.

      Pages: 174 - 181
      Abstract: Global research collaborations today require reliable and secure dedicated network connections to facilitate data communications between collaborating partners. To deal with the deluge of data, dedicated connections are needed to transport data in a highly efficient manner. Managing such links, which often cross multiple administrative domains with heterogeneous infrastructure, poses many compelling research challenges, one of which is interdomain network monitoring. In this article, a multidomain circuit monitoring system, CMon, is introduced. Using some services of G''ANT perfSONAR MDM, CMon is able to provide end-to-end circuit monitoring services with great flexibility, extensibility, and vendor independence, regardless of the underlying circuit provisioning systems. The architecture of CMon, by using measurement federations, can adapt to either changes in the circuit provisioning system or expansion of network size.

      Abstract: This is the first in a new series of Feature Topics on Communications Education and Training that will appear regularly in IEEE Communications Magazine henceforth. It has long been appreciated that successful design, implementation, maintenance, optimization, and improvement of modern communications networks require the efforts of a highly educated, well trained, and dedicated workforce. In recent years, various initiatives have been undertaken in both academia and industry that seek to improve our capacity to educate and train both current and future communications workers. These range from new learning technologies and pedagogies and new university accreditation programs to advanced cooperative education programs, training alliances, and industry certification programs.

  • Software-defined radio: a new paradigm for integrated curriculum delivery
    • Authors: Bil??n; S.G.;Wyglinski, A.M.;Anderson, C.R.;Cooklev, T.;Dietrich, C.;Farhang-Boroujeny, B.;Urbina, J.V.;Edwards, S.H.;Reed, J.H.;

      Abstract: Software-defined radio is a rapidly developing field that is driving the development of and innovation in communications technology, and promises to significantly impact all communications sectors. Entities developing these SDR systems require a trained workforce that has been prepared with the mindset, knowledge, skills, and tools required to address both the system (breadth) and technical (depth) aspects of SDR systems. Developing SDRs necessarily involves a collection of disciplines including, but not limited to, electromagnetics, radio-frequency engineering, communications, digital signal processing, embedded systems, computer programming, and systems engineering. Whereas electrical engineering and computer science and engineering curricula at the university level may include courses in all of these areas, a student''s typical curriculum does not; nor does it usually involve the integration of all these topics. However, SDR can be employed as an integrative construct that facilitates systems thinking and cross-domain learning via peers. In this article, we present several significant educational efforts across six U.S. universities that have developed integrated curricula in SDR, most including a significant laboratory component.

      Pages: 194 - 201
      Abstract: Wireless communications is taught in most electronics degree curricula worldwide, where the main focus is the theory of communications. While it is essential that students learn the theory of communications, this is not enough to prepare them for their careers in industry. This is due to the fact that there are several practical challenges in designing and implementing wireless communications systems that are overlooked when focusing only on theory. Hence, in this article we describe the main challenges in designing practical communications systems, and demonstrate how the National Instruments Universal Software Radio Peripheral can be used for introducing and educating students about these challenges.

  • System-oriented communications engineering curriculum: teaching design
           concepts with SDR platforms
    • Authors: Petrova; M.;Achtzehn, A.;M??h??nen, P.;
      Pages: 202 - 209
      Abstract: Communications capabilities are becoming an integral part of common infrastructure, and are embedded in an increasing number of consumer products to enable the Internet of Things and networked applications. The proliferation of (wireless) communications has, not surprisingly, generated new demands for higher education. First, if we consider communications engineering students, we observe that they need to be readily equipped with sophisticated skills beyond the theoretical domain in order to successfully fulfill implementation tasks and tackle practical design problems. This requirement is particularly emphasized by their future industrial employers. Second, as the integration of communications capabilities becomes widespread, there is a need to also provide core competencies to non-communications engineering students and industry professionals. These students come from a variety of fields such as mechanical engineering and computer science. They want, and indeed need, the practical tools and knowledge to develop and test communications systems, but often lack the traditional electrical engineering and signal processing background. The curriculum and the way we teach these professionals have to adapt to new challenges. In this article we outline how close integration of software defined radios into the university curriculum can help the community meet some of these challenges. In particular, we describe our early efforts to re-engineer a part of our curriculum, and present our novel approach to merge laboratories and lectures to provide a more ''hands-on'' experience to a heterogeneous student body.

  • WWVB time signal broadcast: an enhanced broadcast format and multi-mode
    • Authors: Liang; Y.;Eliezer, O.;Rajan, D.;Lowe, J.;
      Pages: 210 - 217
      Abstract: WWVB is a broadcast station, operated by the National Institute of Standards and Technology, which has been broadcasting time information to radio-controlled clocks (RCC) throughout the continental US since 1965. The transmitted information includes the year (excluding the century), day, hour, minute, and notifications for leap seconds and for daylight saving time (DST) transitions. By receiving this information from WWVB, RCCs can acquire and maintain accurate timing and automatically adjust for DST transitions and leap seconds. The legacy amplitude modulation (AM)-based broadcast format, introduced in the 1960s, while allowing for a simple implementation of a receiver with the technology of that era, exhibits low efficiency. Consequently, RCCs based on it often fail to receive reliably, particularly in locations that are distant from the station, such as on the East Coast. To improve the station''s coverage, an enhanced broadcast format, based on the addition of phase modulation (PM), was deployed in 2012. This article presents an overview of this new broadcast format and its enhanced features, including its modulation scheme, information encoding, channel coding, and transmission modes. These features enable more reliable receiver performance and greater time-keeping accuracy at reduced power consumption. Additionally, various challenges and considerations associated with the design of receivers for the new broadcast format are presented.

  • Revisiting the issue of the credibility of simulation studies in
           telecommunication networks: highlighting the results of a comprehensive
           survey of IEEE publications
    • Authors: Sarkar; N.I.;Guti??rrez, J.A.;
      Pages: 218 - 224
      Abstract: In a series of papers by Pawlikowski and his team, they warned about a deep crisis of credibility in simulation studies for the performance evaluation of telecommunication networks. The goal of this article is to revisit the investigation on simulation credibility and to extend the previous research in this area by presenting the results of a comprehensive survey of over 8370 IEEE publications (2007''2009) on telecommunication networks which appeared in the proceedings of IEEE Transactions on Communications (TC), IEEE/ACM Transactions on Networking (TN), IEEE Infocom, IEEE ICC, and IEEE Globecom. These proceedings were selected based on their popularity and relevance to our study. Besides simulation credibility, we also report on the commonly used simulation tools and performance analysis methodology adopted by the authors of the surveyed papers. Our findings show that a significant number of authors did not provide information of the simulation tools used or, even when they did, there was not enough information about the CI or SE of simulation results presented in the surveyed papers. Thus, there is no significant change with respect to quality and credibility of the simulation studies revised and the deep crisis of credibility still remains. The research design most authors prefer is a hybrid one where both simulation and analytic methods are being used for network performance analysis. Finally, we provide guidelines for the best practice of using simulation tools for the performance evaluation of telecommunication networks.

  • Network adaptability from disaster disruptions and cascading failures
    • Authors: Mukherjee; B.;Habib, M.F.;Dikbiyik, F.;
      Pages: 230 - 238
      Abstract: Disasters can cause severe service disruptions due to large-scale correlated cascading failures in telecom networks. Major network disruptions due to disasters ''' both natural (e.g., Hurricane Sandy, 2011 Japan Tsunami) and human-made (e.g., 9/11 terrorist attack) ''' deprive the affected population of essential network services for weeks and severely hamper rescue operations. Many techniques exist to provide fast network protection, but they are optimized for limited faults without addressing the extent of disaster failures. Thus, there is a pressing need for novel robust survivability methods to mitigate the effects of disasters on telecom networks. While researchers in climatology, geology, and environmental science have been studying how to predict disasters and assess disaster risks for certain regions, networking research can exploit this information to develop novel methods to prepare networks to handle disasters with the knowledge of risky regions and to better prepare them for a predicted disaster. The events during the aftermath of a disaster should also be considered. For instance, methods to re-arrange network resources and services on a partially damaged network, which is the property of a self-organizing network, should be developed, and new algorithms to manage the post-disaster traffic deluge and to relieve the rescue operations after a disaster, with the knowledge of the post-disaster failures, should be investigated. Since cloud services today are an integral part of our society and massive amounts of content/services have been created and shared over the cloud, loss/disruption of critical content/ services caused by disasters can significantly affect the security and economic well being of our society. As the network is becoming increasingly an end-to-content (vs. end-toend) connection provider, we have to ensure reachability of content from any point of a network, which we call content connectivity (in contrast to network connectivity) after di- aster failures. This article presents the nature of possible disruptions in telecom networks caused by disaster events, and sheds light on how to prepare the network and cloud services against disasters, and adapt them for disaster disruptions and cascading failures.
