An Integrated Metrics Based Routing Protocol for Wireless Mesh Networks

Abstract

Providing users with high-quality,high-performance communication links is one of the most important challenges in wireless mesh networks.However,experiments and applications show that the routing protocols in Ad Hoc networks cannot fully satisfy the performance requirements of wireless mesh networks.Combining optimized link state routing protocol with cross-layer design theory,a novel routing protocol based on integrated metrics is proposed for Infrastructure/Backbone wireless mesh networks.The new protocol greatly optimized routing performance by making use of a brand-new routing metric,which takes into account two factors in route selection:link length and link communication efficiency.The simulation results show that the proposed routing protocol improves the packet delivery ratio,reduces the end-to-end delay,and achieves load balance in the route selection process.
