针对基于IEEE 802.11标准的多信道无线网状网中采用接纳控制方案,设计出一种分布式的低干扰且带宽保证的最短路径路由协议;该协议通过分布式免干扰的链路调度机制,并根据带宽要求为链路分配相应时槽数,以实现带宽保证的链路流。NS-2模拟实验结果显示,该协议能为通信链路提供有效的带宽保证,对于有带宽保证要求的业务,可实现较高的通信连接成功概率,具有良好的性能。
This paper presented a distributed bandwidth-aware routing protocol based on multi-channel wireless mesh networks by utilizing admission control. The protocol used distributed link schedule to prevent interference and guaranteed enough bandwidth for link flow by slot assignment schemes. It made NS-2 simulations to test the protocol. The results show that this protocol achieves much better performance, it can effectively provide bandwidth guaranteed path according to connection requests.
