The density of wireless devices in homes, offices, and public spaces is expected to continue to increase with time, making it important to develop strategies to fully utilize the available wireless spectrum. Towards this goal, this project investigates protocol mechanisms that can exploit the availability of multiple wireless channels within a single wireless mesh network, while requiring each host or router to use only a small number of wireless interfaces. With a small number of interfaces, although a single host may not be able to use all the channels simultaneously, a group of hosts in a given neighborhood may be collectively able to use all the channels. This project strives to develop suitable protocols to translate this intuition into reality. The project is expected to have an impact on theory and practice of wireless mesh networking, by improving performance achievable in such networks. The anticipated results of the project include: Fundamental capacity analysis that establishes fundamental limits on performance of multi-channel wireless mesh networks, Network layer and link layer mechanisms that exploit availability of multiple wireless channels, while using a small number of interfaces at the hosts, andExperimental demonstration and evaluation of selected mesh networking protocols.

随着时间的推移，家庭、办公室和公共场所的无线设备密度预计将继续增加，因此制定充分利用可用无线频谱的策略非常重要。为了实现这一目标，该项目研究了可以利用单个无线网状网络内多个无线通道的可用性的协议机制，同时要求每个主机或路由器仅使用少量无线接口。对于少量接口，尽管单个主机可能无法同时使用所有通道，但给定邻居中的一组主机可能共同能够使用所有通道。该项目致力于开发合适的协议来将这种直觉转化为现实。该项目预计将通过提高无线网状网络的性能来对无线网状网络的理论和实践产生影响。该项目的预期结果包括： 基本容量分析，确定多通道无线网状网络性能的基本限制，利用多个无线通道的可用性的网络层和链路层机制，同时在主机上使用少量接口，对选定的网状网络协议进行实验演示和评估。
