    In this article, an adaptive distributed MIMO multihop network was presented, and the e2e outage probability was derived as the QoS parameter. The task of assigning the physical resources transmit power and the time to reduce the total transmit power while meeting a given QoS constraint was introduced and solved by means of common convex optimization tools. As shown by numerical investigations, the adaptive multihop scheme outperforms the direct transmission and the nonadaptive multihop scheme significantly. Furthermore, a joint optimization of power and time (or bandwidth) is favorable for systems with equal link strength. View full abstract»

  • Maximizing network throughput

    In this article, we investigated, using game theory, the competition in a shared open spectrum between two operators. We proposed a new way of maximization of the network throughput, and we provided new ways toward the provision of fairness. We computed an NE and NBS of an NPG and CPG, respectively. Regarding strategies and the best game to be played, there is no single answer. The best solution depends on the perspective. However, the CPG is more effective in terms of clients' experienced quality of service. Our future work involves experimenting with more than two APs in the shared area and evaluating various quality of service metrics. View full abstract»

  • Multihop cellular networks toward LTE-advanced

    This article presents the architecture of MCN toward 3G LTE-Advanced with TDD. On the assumption that L2 RN and L3 RN can provide their own RRM functions, several important RRM functions including routing, link adaptation, and scheduling in MAC layers at RNs can help the eNB to handle the radio resources efficiently. In general, the RN with higher implementation complexity has the ability to provide more flexible RRM with more overhead. Our dynamic system-level simulations show that the MCN outperform the networks without relaying in terms of SINR and throughput. View full abstract»

  • Awareness networking in wireless environments

    This article presented a platform for awareness networking, targeted for distribution of locally relevant control information between nodes in heterogeneous wireless environments. This concept can be leveraged in many different ways and purposes, as shown with the examples given, which range from network discovery, to functionalities required in cognitive radio systems to distributed services facilitating localized mobile social networking. Although a wide range of applications can be envisioned, the same basic solution for distributing locally relevant control information applies to all of them. Future research work on awareness networking is required on multiple areas, covering the technical details of the connectivity solution, details of the distributed algorithms, functionalities, and services, and the regulatory support required for their realization.

    Home users form the largest proportion of Internet users globally today. With the way broadband Internet usage is likely to emerge as a future communication medium interconnecting families and household communities, we visited some of the issues and future problems that might hamper content sharing among users tomorrow. In so doing, we developed a simpler, intuitive, and more resilient content-sharing architecture that is designed to operate seamlessly with much of tomorrow's networks and protocols. Our findings prove that it is not only possible to build an architecture that can coexist with today's networks but also capable of doing so with little performance difference to the end user.

  • Statistical multiplexing of video programs

    In this work, we propose new R-D models for the SM system using H.264/AVC video encoders. These models take into account the interframe dependencies used for performing motion compensation between a reference and a predicted frame, even I and P frames or P and P frames. In this article, the dependencies specified in terms of impact of encoding parameters of a given frame over the next one is proved experimentally and interpreted theoretically by considering the quantization of an IRS-AR source model with varying QPs. Theoretical R-D curves obtained for this model show a behavior similar to the curves obtained using H.264/AVC video coder. Encouraging results have been obtained, but the proposed model still needs to be refined to be used within an SM. View full abstract»

  • Trust in M2M communication

    Machine-to-machine (M2M) communication is viewed as one of the next frontiers in wireless communications. M2M communication applications and scenarios are growing and lead the way to new business cases. Because of the nature of M2M scenarios, involving unguarded, distributed devices, new security threats emerge. The use case scenarios for M2M communication also address the new requirement on flexibility, because of deployment scenarios of the M2ME in the field. We believe that these new requirements require a paradigm shift. One important pillar of such a shift will be a new, more balanced mix of device-centric trust and traditional enforcement of security properties. View full abstract»

    The use of video-based surveillance systems in combination with an intelligent technical automatic image-processing system for metropolitan railways, to alert the operator's service staff is considered today by many viable and promising technologies for both purposes. Therefore, for the first time worldwide, the Dresden University of Technology, in cooperation with TelSys, had developed a video image-processing safety kernel, employing only algorithms that permit safety analyses that are traditionally performed for electronic signaling systems.The basic idea of the video guideway intrusion detection system (GIDS) consisted of using standard railway-proven video cameras to supervise critical areas of the infrastructure.

  • Braking energy recuperation

    This article estimates energy savings through braking energy recuperation and capital cost savings through increased substation spacing. The TCRs provide advantages over diode rectifiers: better voltage regulation and fault current limiting translating into some operational savings (energy savings through increased DC bus voltage, improved service life) and capital savings (reduced number of substations). Assuming just 15% spacing increase in the new substation installations, capital savings with TCR are more than 10%. The additional savings with RTCR over SDR are through braking energy recuperation back to the AC line. Energy savings can be as high as 50% depending on the train speed profile, train car efficiency, rail resistance, etc. Upgrading existing SDR substations to RTCR gives substantial energy savings and has a payback of two to two and a half years, improving throughput up to 60% without incurring additional real estate and construction expenses.
