Wireless mesh networking based on IEEE 802.11a/b/g, 802.16a or other technologies has been drawing significant attention in both industry and academia recently, as it demonstrates some extremely important characteristics, such as easy deployment, low cost, and potential high capacity. However, it also faces a variety of challenges relating to quality of service (QoS) provisioning, efficient radio resource usage, scalability, and other issues. The long term objective of this research is to study QoS provisioning for multimedia traffic in interconnected wireless and wireline networks where users can move freely to anywhere at any time. The objective of the research during the next five years is to propose and investigate performance of scalable radio resource management schemes in wireless mesh networks that can provide satisfactory QoS for more mobile users. In the proposed research, the radio resource management will consider how to best exploit the available capacity based on specific network conditions to support both the link layer and network layer transmissions. The resource management will also consider user mobility and handoffs in order to support mobile user's services seamlessly. A cross-layer approach allows the resource management to fully access to the benefit from different network layers. Various approaches will be studied to make the proposed resource management schemes scalable to work in large mesh networks. The proposed research is expected to achieve more effective and efficient radio resource utilization. It will also make wireless mesh networks easy to be deployed in not only local areas, but also city-wide and larger areas.

基于IEEE 802.11a/b/g、802.16a等技术的无线网状网络由于具有易部署、低成本和潜在的高容量等特点，近年来受到了业界和学术界的广泛关注。然而，它也面临着与服务质量（QoS）供应、有效的无线电资源使用、可伸缩性和其他问题相关的各种挑战。本研究的长期目标是研究在用户可以随时随地自由移动的互联无线和有线网络中多媒体流量的QoS配置。未来五年的研究目标是提出和研究无线网状网络中可扩展的无线电资源管理方案的性能，为更多的移动用户提供满意的QoS。在提出的研究中，无线电资源管理将考虑如何根据特定的网络条件最好地利用可用容量来支持链路层和网络层传输。资源管理还将考虑用户的移动性和切换，以便无缝地支持移动用户的服务。跨层方法允许资源管理充分利用不同网络层的优势。将研究各种方法，以使所提出的资源管理方案可扩展到大型网状网络中。拟议的研究预计将实现更有效和高效的无线电资源利用。它还将使无线网状网络不仅易于在局部地区部署，而且易于在全市和更大的区域部署。
