  • Mobile crowd sensing: Part 1 [Guest Editorial]
    • Authors: Guo; B.;Calabrese, F.;Miluzzo, E.;Musolesi, M.;
      Pages: 20 - 21
      Abstract: Successful city management relies on urban dynamics and social event monitoring to provide essential information for decision making. In traditional sensing techniques such as wireless sensor networks (WSNs), distributed sensors are leveraged to acquire real-world conditions. However, static sensing suffers from several problems, such as insufficient node coverage, high installation/ maintenance cost, and lack of scalability.

  • Mobile crowd sensing in space weather monitoring: the mahali project
    • Authors: Pankratius; V.;Lind, F.;Coster, A.;Erickson, P.;Semeter, J.;
      Pages: 22 - 28
      Abstract: Space weather refers to the conditions and evolution of Earth's near space environment including electron density variations in the ionosphere. This environment is influenced by both the Sun and terrestrial processes, and has an impact on communications, navigation, and terrestrial power systems. The recent discovery of clear signatures in the ionosphere related to tsunamis and earthquakes suggests that the ionosphere itself may serve as a valuable and versatile sensor, registering many types of Earth- and space-based phenomena. To realize this potential, ionospheric electron density must be monitored through a dense wide-area sensor mesh that is expensive to realize with traditional deployments and observation techniques. Crowdsourcing can help pursue this novel direction by providing new capabilities, including an increase in the number of sensors as well as expanding data transport capabilities through participating devices that act as relays. This article describes the Mahali project, which is currently at the beginning of exploring these promising techniques. Mahali uses GPS signals that penetrate the ionosphere for science rather than positioning. A large number of ground-based sensors will be able to feed data through mobile devices into a cloud-based processing environment, enabling a tomographic analysis of the global ionosphere at unprecedented resolution and coverage. This novel approach brings the exploitation of the ionosphere as a global earth system sensor technologically and economically within reach.

  • Opportunities in mobile crowd sensing
    • Authors: Huadong Ma;Dong Zhao;Peiyan Yuan;
      Pages: 29 - 35
      Abstract: Mobile crowd sensing is a new paradigm that takes advantage of pervasive mobile devices to efficiently collect data, enabling numerous largescale applications. Human involvement is one of the most important features, and human mobility offers unprecedented opportunities for both sensing coverage and data transmission. In this article, we investigate the opportunistic characteristics of human mobility from the perspectives of both sensing and transmission, and discuss how to exploit these opportunities to collect data efficiently and effectively. We also outline various open issues brought by human involvement in this emerging research area.

  • Surrogate mobile sensing
    • Authors: Dong Wang;Abdelzaher; T.;Kaplan, L.;
      Pages: 36 - 41
      Abstract: The proliferation of smart phones with sensing capabilities motivates exploring the applicability limits of (phone-based) mobile sensing. While a phone can directly measure variables such as location, acceleration, and orientation, other interesting quantities one may want to measure have higher-level semantics that a phone does not directly recognize. For example, one might want to map parking lots that are free after hours, or restaurants that are popular after midnight. How can we measure such higher-level logical quantities using sensors on phones? Techniques that address this question fall in the broad area of surrogate sensing, defined as inferring high-level logical quantities by measuring weaker surrogates. The surrogates in question are variables that can be sensed using a phone, but are only weakly related to the original high-level logical quantities one is really after. The key challenge is to exploit appropriate aggregation techniques that leverage the availability of large numbers of phones to overcome the poor quality of individual surrogates. Recently, significant advances have been made in understanding the quality limits of surrogate sensing. This article overviews the main ideas and insights underlying these advances.

  • 4W1H in mobile crowd sensing
    • Authors: Daqing Zhang;Leye Wang;Haoyi Xiong;Bin Guo;
      Pages: 42 - 48
      Abstract: With the rapid proliferation of sensor-rich smartphones, mobile crowd sensing has become a popular research field. In this article, we propose a four-stage life cycle (i.e., task creation, task assignment, individual task execution, and crowd data integration) to characterize the mobile crowd sensing process, and use 4W1H (i.e., what, when, where, who, and how) to sort out the research problems in the mobile crowd sensing domain. Furthermore, we attempt to foresee some new research directions in future mobile crowd sensing research.

  • Trust and privacy in mobile experience sharing: future challenges and
           avenues for research
    • Authors: Krontiris; I.;Langheinrich, M.;Shilton, K.;
      Pages: 50 - 55
      Abstract: Mobile consumer devices are increasingly used as personal sensing instruments, where users record their daily habits, track their physical activity, or monitor their health. Research is underway to extend today's diversity of vendor-designed "walled garden" repositories, ultimately repositioning individuals as producers, consumers, and remixers of a vast openly shared public data set. By empowering people to easily measure, report, and compare their own personal environments, such tools transform everyday citizens into reporting agents who uncover and visualize unseen elements of their own everyday experiences. With this important new shift in mobile device usage - from a communication tool to a ubiquitous "experience sharing instrument" - comes a new dimension in trust and privacy challenges. Today's privacy and trust tools that address web surfing and simple location-based services already struggle to be adopted in practice. We argue that in order to prepare for tomorrow's sensor sharing, privacy and trust must be addressed holistically, incorporating both technical approaches and actual sharing behavior. This article summarizes the results of a five-day Dagstuhl Seminar on mobile experience sharing and outlines future research necessary in this domain.

  • Recommending travel packages based on mobile crowdsourced data
    • Authors: Zhiwen Yu;Yun Feng;Huang Xu;Xingshe Zhou;
      Pages: 56 - 62
      Abstract: Mobile crowdsoured data from location based social network services (LBSNs) provide information on individual's preferences for locations. In this article, we propose a travel package recommendation system to help users make travel plans by leveraging mobile crowdsourced data. We extract user preferences, discover points of interest (POIs), and determine location correlations from check-in records. We then generate personalized travel packages by considering user preferences, POI characteristics, and temporalspatial constraints such as travel time and starting location. A prototype system is built and evaluated on real-world crowdsourced data from Jie Pang, one of the most popular LBSNs in China.

  • Large-scale immersive video conferencing by altering video quality and
           distribution based on the virtual context
    • Authors: Safaei; F.;Pourashraf, P.;Franklin, D.;
      Pages: 66 - 72
      Abstract: Current video conferencing applications do not scale to support a large number of participants. This article describes an IVC system that combines the best attributes of video conferencing and multi-user virtual environments. It is shown that each participant of IVC has a virtual context that is defined by his/her perspective and perception about the quality and relevance of video and audio of others. The virtual context determines both the visibility status and the required quality of videos of participants. This information can be used to dynamically alter the multicast trees that are formed among clients for the purpose of multimedia dissemination so that only the relevant videos are transmitted to end users. In addition, it is possible to reduce the video quality of a given user in response to the virtual context without the degradation having any perceptual impact. The combination of these factors reduces the required upload and download bandwidth of clients by more than 90 percent on average, making IVC highly scalable to support very large gatherings.

  • Smart health: A context-aware health paradigm within smart cities
    • Authors: Solanas; A.;Patsakis, C.;Conti, M.;Vlachos, I.;Ramos, V.;Falcone, F.;Postolache, O.;Perez-martinez, P.;Pietro, R.;Perrea, D.;Martinez-Balleste, A.;
      Pages: 74 - 81
      Abstract: The new era of mobile health ushered in by the wide adoption of ubiquitous computing and mobile communications has brought opportunities for governments and companies to rethink their concept of healthcare. Simultaneously, the worldwide urbanization process represents a formidable challenge and attracts attention toward cities that are expected to gather higher populations and provide citizens with services in an efficient and human manner. These two trends have led to the appearance of mobile health and smart cities. In this article we introduce the new concept of smart health, which is the context-aware complement of mobile health within smart cities. We provide an overview of the main fields of knowledge that are involved in the process of building this new concept. Additionally, we discuss the main challenges and opportunities that s-Health would imply and provide a common ground for further research.

  • Living on the edge: The role of proactive caching in 5G wireless networks
    • Authors: Bastug; E.;Bennis, M.;Debbah, M.;
      Pages: 82 - 89
      Abstract: This article explores one of the key enablers of beyond 4G wireless networks leveraging small cell network deployments, proactive caching. Endowed with predictive capabilities and harnessing recent developments in storage, context awareness, and social networks, peak traffic demands can be substantially reduced by proactively serving predictable user demands via caching at base stations and users' devices. In order to show the effectiveness of proactive caching, we examine two case studies that exploit the spatial and social structure of the network, where proactive caching plays a crucial role. First, in order to alleviate backhaul congestion, we propose a mechanism whereby files are proactively cached during off-peak periods based on file popularity and correlations among user and file patterns. Second, leveraging social networks and D2D communications, we propose a procedure that exploits the social structure of the network by predicting the set of influential users to (proactively) cache strategic contents and disseminate them to their social ties via D2D communications. Exploiting this proactive caching paradigm, numerical results show that important gains can be obtained for each case study, with backhaul savings and a higher ratio of satisfied users of up to 22 and 26 percent, respectively. Higher gains can be further obtained by increasing the storage capability at the network edge.

  • Precise: Privacy-aware recommender based on context information for cloud
           service environments
    • Authors: Celdran; A.;Perez, M.;Garcia Clemente, F.;Martinez Perez, G.;
      Pages: 90 - 96
      Abstract: Context-aware systems based on location open up new possibilities to users in terms of acquiring custom services by gathering context information, especially in systems where the high mobility of users increases their usability. In this context, this article presents a privacy-preserving solution offering context-aware services based on location in MCC. We propose a middleware, called PRECISE, which provides users with custom context-aware recommendations. These recommendations are given by considering the context information, and the users' locations, privacy policies, and previously visited places. MCC plays a key role in this solution, moving the data processing and storage needs to the cloud, as well as further advantages such as elasticity and load balancing. A thorough discussion when comparing PRECISE with other related works confirms that our solution improves the most relevant proposals so far.

  • Context-aware service composition and delivery in NGSONs over SDN
    • Authors: Paganelli; F.;Ulema, M.;Martini, B.;
      Pages: 97 - 105
      Abstract: NGSON is an IEEE sponsored effort to standardize an open service ecosystem where different stakeholders may cooperate to satisfy users' ever changing requirements by composing and delivering services dynamically across different service providers and network operators' domains. A main distinguishing feature of NGSON is context awareness, that is, the capability of collecting, processing, and using context information to drive the interactions of the NGSON overlay nodes with service and network operators' infrastructures for guaranteeing an optimal user experience. Recent advances in network control and management technologies, such as SDN, NFV, and service-oriented networking paradigms, are expected to make the network effectively able to cope with application service requirements in a more flexible, timely, and agile manner. In this article we discuss how NGSON, which already incorporates several aspects of virtualization, could take advantage of network virtualization mechanisms and programmable traffic steering capabilities to enhance and effectively support context-aware service composition along with adaptive service delivery. We propose an architectural model for NGSON that leverages these novel network service control capabilities and illustrate through a use case how this model could effectively be put into operation.

  • Context-aware vehicular cyber-physical systems with cloud support:
           architecture, challenges, and solutions
    • Authors: Jiafu Wan;Daqiang Zhang;Shengjie Zhao;Yang; L.;Lloret, J.;
      Pages: 106 - 113
      Abstract: The advances in wireless communication techniques, mobile cloud computing, and context- aware technologies boost a growing interest in the design, development, and deployment of vehicular networks for emerging applications. This leads to an increasing evolutionary tendency to change from vehicular networks toward cloud-assisted context-aware vehicular cyberphysical systems. In this article, we first propose a multi-layered context-aware architecture and introduce two crucial service components, vehicular social networks and context-aware vehicular security. Then we propose an application scenario regarding the context-aware dynamic parking services by illuminating the cloud-assisted architecture and logic flow. Finally, we investigate the challenges and possible solutions, including context-aware safety hazard prediction, context-aware dynamic vehicle routing, and context-aware vehicular clouds.

  • Optical multi-service core and access networks [Series Editorial]
    • Authors: Gebizlioglu; O.S.;Jain, V.;
      Pages: 114 - 114
      Abstract: The global optical communications industry has continued to show progress in all segments from access to core networks through 2014. The two most notable trends of 2013 have been expanding in 2014: 1) the emergence of the packet optical transport system (P-OTS) concept with the service provider goal to build a common network infrastructure by integrating Ethernet, IP/multiprotocol label switching (MPLS), and dense wavelength-division multiplexing (DWDM); 2) intensifying focus and attention on network functions virtualization (NFV) and software-defined networking (SDN) to provide service providers with the tools for more effective operation and management of optical communications networks. Some global service providers have been establishing and announcing their target timeframes for transitioning to all-IP network operations, while major industry standards organizations and fora have been working to publish their guidelines and frameworks for NFV and SDN. These important trends are expected to gain additional momentum through the rest of 2014 as the industry continues to develop to meet the growing global communications needs.

  • Application of optical multilevel transmission technique in WDM/OCDM-based
           core networks
    • Authors: Beyranvand; H.;Salehi, J.;
      Pages: 116 - 125
      Abstract: In this article, we present a new scheme to improve the performance of multiservice WDM/OCDM-based core networks. The idea is based on utilizing optical multilevel transmission technique (MLTT) to mitigate the multiple access interference (MAI) effect of OCDM. In this multilevel-multiclass network, users of each class are divided into multiple groups and users of each group are allowed to transmit at a specific power level. We demonstrate that, the proposed multilevel-multiservice scheme outperforms previously introduced multiservice WDM/OCDM based networks. This is due to the interference reduction property of MLTT, and this superiority can be further enhanced by using advanced optical logic gates. The proposed scheme is a modification implemented at the data plane by upgrading the intermediate optical routers to support MLTT. In the proposed network model, data and control planes are separated and can be designed independently. However, our results reveal that a data-planeaware controlling approach, which considers the information of the data plane, outperforms a data-plane-unaware algorithm in terms of average error probability.

  • Cost analysis of network sharing in FTTH/PONs
    • Authors: Schneir; J.;Yupeng Xiong;
      Pages: 126 - 134
      Abstract: This article examines the cost implications of a network-sharing scheme for different fiber to the home/passive optical network architectures. Varied metrics are employed to understand the effect of a network-sharing arrangement on costs. The results show that for the majority of cases studied, the cost per home connected and the payback period increase when employing a network-sharing scheme, but the initial investment is strongly reduced. The reuse of existing passive infrastructure does not bring any cost advantage in comparison to the standalone scenario, but it helps to reduce the total cost per home connected.

  • A case for assisted partial timing support using precision timing protocol
           packet synchronization for LTE-A
    • Authors: Pearson; T.;Shenoi, K.;
      Pages: 136 - 143
      Abstract: North American service providers are in the process of upgrading their radio access networks with next generation LTE equipment. They are finalizing a 4G rollout that involves highly stringent timing requirements, but in many cases they are relying on sole-source synchronization by using Global Navigation Satellite System (GNSS). Natural occurring disturbances, as well as unintentional radio frequency jamming, intentional jamming, and spoofing, make GNSS vulnerable to interference. This article presents a novel approach for addressing the issue of GNSS vulnerability by introducing a standard means of providing a redundant packet-based synchronization source for LTE base stations. It also describes how this new approach can mitigate noise caused by asymmetry and transit delay variation in packet networks.

  • Cross-community sensing and mining
    • Authors: Bin Guo;Zhiwen Yu;Daqing Zhang;Xingshe Zhou;
      Pages: 144 - 152
      Abstract: With the developments in information and communications technology (ICT), people are involving in and connecting via various forms of communities in the cyber-physical space, such as online communities, opportunistic (offline) social networks, and location-based social networks. Different communities have distinct features and strengths. With humans playing the bridge role, these communities are implicitly interlinked. In contrast with the existing studies that mostly consider a single community, this article addresses the interaction among distinct communities. In particular, we present an emerging research area - cross-community sensing and mining (CSM), which aims to connect heterogeneous, cross-space communities by revealing the complex linkage and interplay among their properties and identifying human behavior patterns by analyzing the data sensed/collected from multi-community environments. The article describes and discusses the research background, characters, general framework, research challenges, as well as our practice of CSM.

  • Media network as a service
    • Authors: Cicic; T.;Elmokashfi, A.;
      Pages: 153 - 159
      Abstract: The videoconferencing industry is undergoing the most substantial change in a decade. Demand for advanced collaboration functionality and the highest quality of media presentation is meeting the requirement for Internet-based "over the top" communication, allowing unlimited communication between the organizations and individuals. We claim that these two contradictory requirements are best conciliated through deployment of a cloud service with elements of Network and Infrastructure as a Service required to support global videoconferencing. The operational architecture we present enjoys the full benefits of the cloud networking model, including elastic scaling, on-demand resource availability, and a no-capex service model. The videoconferencing infrastructure requirements on the application level, and the quality requirements on the network level, are addressed in the single platform, opening new optimization possibilities. We describe the network-level wide-area routing and service discovery mechanisms we have deployed to improve the videoconferencing user experience through reduction of communication delay and packet loss. We further describe the service economy model, discussing the key trade-offs relevant for network cloud operations.
