中文摘要：
为用户提供高质量、高性能的通信链路是无线Mesh网路由协议所面临的重要挑战,而当前从AdHoc网络沿袭下来的路由协议并不能够满足无线Mesh网的性能要求.文中以OLSR协议为原型,结合跨层优化理论,为基础设施架构的无线Mesh网提出了一种新颖的、基于综合判据的路由协议.该协议通过跨层操作机制综合考虑无线链接的长度及通信效率对链接性能的影响,从而达到优化路由选择的效果.仿真结果表明,所提出的路由协议能够有效地提高网络中分组的递交率,降低端到端的延时,并且能够在一定程度上达到负载均衡的路由效果.
英文摘要：
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.
