NeTS-NBD: Multi-Channel Wireless Mesh Networks: Capacity, Protocols, and Experimental Evaluation

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，本项目研究协议机制，可以利用多个无线信道的可用性在一个单一的无线网状网络，同时要求每个主机或路由器只使用少量的无线接口。在接口数量较少的情况下，尽管单个主机可能无法同时使用所有信道，但给定邻域中的一组主机可能能够共同使用所有信道。该项目致力于开发合适的协议，将这种直觉转化为现实。该项目预计将对无线网状网络的理论和实践产生影响，通过提高此类网络的性能。该项目的预期成果包括：确定多信道无线网状网络性能基本限制的基本容量分析，利用多个无线信道的可用性，同时在主机上使用少量接口的网络层和链路层机制，以及选定网状网络协议的实验演示和评估。

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.
