    In the First Report and Order, the FCC allocated 40 MHz of spectrum at 2,360-2,400 MHz for MBAN use on a secondary basis. The spectrum will accommodate MBAN use through an expansion of the existing Medical Device Radiocommunication Service in Part 95 of FCC rules. This structure, which will permit MBAN devices to operate on a license-by-rule basis in which users will not have to apply for and receive individual station licenses, is expected to lead to a rapid and widespread development of new MBAN applications.

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (902 KB)  

    This article discusses a novel framework for trust-based multidevice collaboration services. This framework opens up significant scope for applications and collaboration opportunities among heterogeneous devices mimicking human interaction. We present a topology map middleware service and a distributed querying application service that run on top of this framework. We are currently working on addressing the key challenges presented and developing new middleware, application services, and optimization techniques that leverage heterogeneous multidevice collaboration such as colocation detection, determining colocation pattern, and task offloading.

  • M2M Scheduling over LTE: Challenges and New Perspectives

    Page(s): 34 - 39
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (687 KB)  

    Machine-to-machine (M2M) communications over cellular networks pose significant challenges as a result of the large number of devices, small data transmissions, and vast applications range. Current solutions based on general packet radio service (GPRS) access proved to be inadequate for supporting the M2M ecosystem. Therefore, advanced cellular network releases, such as long-term evolution (LTE) and LTE-Advanced (LTE-A), should efficiently cater to M2M communications. However, the increase in signaling overhead and diverse quality-of-service (QoS) requirements calls for the development of novel flexible scheduling algorithms. In this article, we present the challenges in facilitating M2M scheduling over existing and future cellular infrastructures, review the related proposals, provide some initial solutions, and identify new perspectives, which pave the way for efficient and smooth migration to M2M-enabled broadband cellular systems.

  • Analysis of Multihop Relaying Networks: Communication Between Range-Limited and Cooperative Nodes

    Page(s): 40 - 47
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (2325 KB)  

    The focus of this article is on analyzing the impact of the number of hops and the number of transmit and receive antennas, at the relay nodes, on the performance of multihop networks. The vision of future wireless networks includes a greater role for ubiquitous ad hoc networks based on multihop transmissions between machines and general mobile devices carried around by users. With this in mind, the standards are set to include greater capabilities and specifications regarding ad hoc mesh networks, especially ones that employ multiple antennas for transmissions. Therefore, there is a need for an in-depth analysis of the performance of such networks. In this analysis, we consider equidistant distributed relays between the source and destination. The statistics of the channels of all hops and the noise powers at all terminals are assumed to be the same. The capacity for the amplify-and-forward (AF) and decode-and-forward (DF) relaying schemes over the single-input single-output (SISO) channel is compared. Moreover, we derive a closed-form solution of the ergodic capacity in the presence of Rayleigh fading for multihop wireless transmissions when the DF-relaying scheme and SISO links between the relay nodes are employed. The quality of service (QoS) of the single-input multiple-output (SIMO) and multiple-input multiple-output (MIMO) [Alamouti space-time block code (STBC)-based scheme] multihop networks are studied, and their performance is compared analytically with each other.

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1600 KB)  

    This work provided an overview of the cognitive networks and systems for a wireless FI by considering the current status and looking forward at the emerging challenges. Emphasis was placed on the opportunistic networking paradigm to provide an insight on research regarding operator-governed ONs that are assumed to be coordinated extension of the infrastructure. For the coordination of operator-governed ONs, cognitive management entities are introduced. Moreover, further emphasis was placed on an operator-governed, end-to-end, autonomic, joint network and services management, which was elaborated as a part of this work. Network and services management is enabled through the definition of a UMF, which has a main goal to unify and federate various research outcomes and will advance the routine management tasks to the level of governance of the entire network.semantic.

    The application of new power electronics equipment to the rolling stocks of electrified railroad vehicles in recent years brought about the benefits of smooth acceleration and braking, higher efficient of propulsion systems, improved power quality, easy-and-simple maintenance of propulsion motor, and even lower procurement and service costs. Hence, they are generally regarded as a blessing and progress for the rail industry. The switching techniques and new power modules with fast response times are key components to make the above functions possible. If a railroad system is built with vehicles and traction power substations are designed for new equipment, then all power components should be designed to withstand the transient dynamic behavior, especially, the switching surge voltage and current. This is usually the responsibility of the general consultant or the turn-key contractor. Unfortunately, the situation in most electrified railroad systems is new, and renovated trains equipped with new converters and new IGBT power modules join service together with old trains and existing traction networks designed and commissioned decades ago. The impact of the switching surge voltage and current will become an issue of great concern, as illustrated by the two cases presented in this article. The problems presented in the two cases were eventually solved by some sort of soft-switching schemes as a remedy or correction solution. Yet, this problem should be addressed and examined in front of the commission phase to avoid impacts. In conclusion, clear specification of surge transients or permissible impacts need to be included in the procurement documents, and field tests are recommended to verify the compatibility of new power converters with the existing equipment in the entire system.

  • Data Transport Networks: Case Studies in a Public Transit Environment

    Page(s): 67 - 72
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1183 KB)  

    Ethernet has become the de facto standard for providing data transport not only throughout the Internet but also for numerous private and industrial networks. Before Ethernet's dominance, circuit-switched networks (or time-division multiplexed networks such as synchronous optical network (SONET) are popular choices for applications that require flexible and reliable data transport. Over the past ten years, packet-switched networks in general (and Ethernet in particular) usurped the role formerly played by these circuit-switched networks. But is this a good development given that not all applications that require data transport are created equally? This article explores the current trend of using packet-switched as opposed to circuit-switched networks in the context of providing data transport for rail-based public transit agencies and, after examining five case studies, draws conclusions that are relevant for public transit agencies.

  • Vehicular Entertainment Systems: Mobile Application Enhancement in Networked Infrastructures

    Page(s): 73 - 79
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1904 KB)  

    Entertainment systems can transform a tedious trip to an enjoyable experience. In this article, we present a new business model and a complete architecture for vehicular entertainment networks that allow users to transfer applications from their mobile terminals to infrastructure elements, such as seat screens, while maintaining control from their terminals. Our approach is compatible with highly successful business models such as application markets, where users download content and services to their devices for future use. This simplifies the process of managing, providing, and updating content services, resulting in reduced maintenance costs and placing the responsibility of content updates and licensing costs on the users. It also reduces infrastructure hardware costs because the use of mobile terminals such as cell phones as control devices eliminates the need for mechanical joysticks or touchscreens in the infrastructures.

    In this article, a novel accident analysis system is proposed to determine the main human factors involved in traffic accidents. Several tests of the system were carried out in a highly realistic truck simulator with a group of professional drivers. The data, collected with the system at the moments before traffic accidents, were used to generate a novel database that was carefully analyzed by a group of traffic safety experts. The validation process shows the reliability of the developed system as a tool for the identification of the main cause of traffic accidents. View full abstract»

  • Automatic Accident Detection: Assistance Through Communication Technologies and Vehicles

    Page(s): 90 - 100
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (3340 KB)  

    In this article, e-NOTIFY system is presented, which allows fast detection of traffic accidents, improving the assistance to injured passengers by reducing the response time of emergency services through the efficient communication of relevant information about the accident using a combination of V2V and V2I communications. The proposed system requires installing OBUs in the vehicles, in charge of detecting accidents and notifying them to an external CU, which will estimate the severity of the accident and inform the appropriate emergency services about the incident. This architecture replaces the current mechanisms for notification of accidents based on witnesses, who may provide incomplete or incorrect information after a long time. The development of a low-cost prototype shows that it is feasible to massively incorporate this system in existing vehicles. View full abstract»
