ABSTRACT IEEE 802.16 mesh mode defines three types of resource scheduling: coordinated centralized, coordinated distributed, and uncoordinated distributed. While the standard defines the required procedures and messages for each scheduler, it does not offer encouraging means to provide performance, reliability, or QoS. In this article we outline the issues of IEEE 802.16 mesh schedulers. We also survey representative proposals and qualitatively evaluate them against these issues. More critically, we identify key challenges that have not been addressed so far in the literature to motivate work in this area of research.

    ABSTRACT: In recent years, because of two way convenience of driving by both Internal Combustion Engine (ICE) and onboard batteries, Plug-in Hybrid Vehicle (PHEV) has earned familiarity, precedence and acknowledgement in the personal transportation sector. However, impact of PHEV charging on the power system stability is a hindrance to large adoption of PHEVs. Hence, there is a need of finding a suitable location for a PHEV charging station in power system incorporating with power system stability indices. In this study, Voltage Sensitivity Factor (VSF) is used to find an optimal place for the PHEV charging station. Simulation results, carried out in a commercial system, show the validity of the proposed methodology.

    ABSTRACT: An efficient scheduling scheme is a crucial part of Wireless Mesh Networks (WMNs)—an emerging communication infrastructure solution for autonomy, scalability, higher throughput, lower delay metrics, energy efficiency, and other service-level guarantees. Distributed schedulers are preferred due to better scalability, smaller setup delays, smaller management overheads, no single point of failure, and for avoiding bottlenecks. Based on the sequence in which nodes access the shared medium, repetitiveness, and determinism, distributed schedulers that are supported by wireless mesh standards can be classified as either random, pseudo-random, or cyclic schemes. We performed qualitative and quantitative studies that show the strengths and weaknesses of each category, and how the schemes complement each other. We discuss how wireless standards with mesh definitions have evolved by incorporating and enhancing one or more of these schemes. Emerging trends and research problems remaining for future research also have been identified.

    ABSTRACT: In this paper, we propose two heuristic algorithms for time slot assignment in IEEE 802.16j relay networks. In the proposed methods, we calculate an appropriate group of time slots for each link in the network or calculate an appropriate group of links for each time slot. We show that the latter algorithm is better in terms of the balance between the calculation time and network performance.
