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.

Key words: wireless multi- hop network, adaptive hazy sight, routing protocols, routing metric
