多信道无线Mesh网络中基于路径尺度的负载平衡路由

为了有效利用无线Mesh网络的多个信道,设计了一种新的路径尺度ERC(expected residual capacity),用来评测路径质量并为节点选择高吞吐量低干扰的路由.同时结合多路径路由的思想,提出了多信道无线Mesh网络的负载平衡路由.该路由利用多个信道来减小通信干扰,并将网络流量尽量均衡地分配到高质量的路径上,有效提高了无线网络的通信质量.仿真结果表明,采用提出的负裁平衡路由算法后,网络整体吞吐量远远胜过单信道网络,而且比一般的多信道路由也有明显改善.此外,网络延迟和丢包率也得到了有效控制.

Load-Balancing Routing Based on Path Metric for Multi-Channel Wireless Mesh Networks

Multi-hop infrastructure wireless mesh networks offer increased reliability, coverage, and reduced equipment costs over their single-hop counterparts, wireless local area networks. Equipping wireless routers with multiple radios further improves the capacity by transmitting over multiple radios simultaneously using orthogonal channels. A good channel-diverse routing is essential for throughput optimization of mesh clients and can alleviate potential congestion on any gateways to the Internet, thereby improv...
