摘　　要：为降低无线多跳网络的路径间干扰,减少路由开销,提出了一种干扰感知的自适应模糊视觉链路状态路由协议.该协议首先将多点中继选择技术和模糊视觉理论相结合,通过控制路由消息发送的时间和距离来减少路由开销,然后采用一种基于跨层优化方法设计的可感知干扰的路由权值,通过正确捕捉流路径内干扰、流路径间干扰和流量负载的变化来优化选路.仿真结果表明,该算法能有效地感知网络干扰特性,实现负载均衡,降低路由开销.In order to decrease the interference in wireless multi-hop networks and to reduce the routing overhead,an interference-aware adaptive hazy sighted link state routing protocol is proposed.In this protocol,first,the multipoint relay selection technology is combined with the fuzzy sighted philosophy,so as to reduce the routing overhead by controlling the transmission time and transmission distance of routing messages.Then,an interference-aware routing metric is designed by means of the cross-layer optimization,and is used to optimize the routing by correctly capturing the intra-flow interference,the inter-flow interference and the traffic load.Simulated results show that the proposed protocol can efficiently capture the interference characteristic of wireless networks,and that it achieves a load balancing and significantly reduces the routing overhead.
