Future wireless communication networks are expected to effectively support large coverage area, heterogeneous multimedia applications, seamless roaming, and quick adaptation to network dynamics resulting from user mobility. As one of candidates for the next generation wireless communication networks, wireless mesh networks are considered to be promising due to their abilities in providing scalability, flexibility, resource efficiency, and quality of service (QoS) provisioning (in terms of network capacity, transmission latency, call dropping/blocking probability, etc.). The significance of wireless mesh networks has been supported by the current standard activities, such as IEEE 802.11s and IEEE 802.16. However, the practical applications of wireless mesh networks are strongly limited due to hostile wireless channel conditions, heterogeneous QoS requirements, non-infrastructure network topology, and multihop transmitting. Therefore, designing practically feasible wireless mesh networks has become a critical and emergent topic in the current telecommunications research field. In order to enhance the research in this field, the proposal focuses on designing effective and efficient network technologies for facilitating practical implementation of wireless mesh networks. Specifically, the proposal will focus on a) the distributed user relaying algorithms for network capacity improvement, b) the routing algorithms for high resource utilization and end-to-end QoS provisioning, and c) the analysis on network performance and the evaluation on the proposed algorithms. The integration of cross-layer design, heterogeneous traffic characteristics, and distributed and scalable requirements will be the major design principle. The research results will be disseminated through publications in journals and conference proceedings, technical seminars, and invention disclosures and patents.
