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.

未来的无线通信网络有望有效地支持大覆盖区域、异构多媒体应用、无缝漫游以及对由用户移动性引起的网络动态的快速适应。作为下一代无线通信网络的候选者之一，无线网状网络由于其在提供可扩展性、灵活性、资源效率和服务质量（QoS）供应（在网络容量、传输延迟、呼叫丢弃/阻塞概率等方面）方面的能力而被认为是有前途的。无线网状网络的重要性已经得到当前标准活动（诸如IEEE 802.11s和IEEE 802.16）的支持。然而，由于恶劣的无线信道条件、异构的QoS要求、非基础设施网络拓扑和多跳传输，无线网状网络的实际应用受到了极大的限制。因此，设计实用可行的无线mesh网络已成为当前电信研究领域的一个重要而紧迫的课题。为了加强在这一领域的研究，该建议的重点是设计有效和高效的网络技术，以促进无线网状网络的实际实施。具体而言，该建议将集中在a）分布式用户中继算法的网络容量的改善，B）路由算法的高资源利用率和端到端的QoS提供，和c）网络性能的分析和评估所提出的算法。跨层设计、异构流量特征以及分布式和可扩展需求的集成将是主要设计原则。研究成果将通过在期刊和会议论文集、技术研讨会、发明披露和专利上发表来传播。
