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.

Abstract:

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 multi-point 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.
