摘要
无线Mesh网SEE-Mesh提案中的按需多径路由算法HWMP存在效率低、扩展性不强等问题。基于先应式路由思想,结合分布与集中式路由的特点,将数据链路层的平面路由方法拉伸成类似于IP路由的多级路由框架,提出了一种新的Mesh网络多径路由协议WMRP。网络仿真与性能评估表明,新协议在多项性能参数上优于原协议,较大提高了执行效率及其可扩展性。
In IEEE SEE-Mesh proposal, the routing protocol-HWMP (Hybrid Wireless Mesh Protocol) has some problems in efficiency and expansibility. Based on proactive routing ideal, making use of the combination characteristic of distributed and centralized routing protocol, a new routing protocol WMRP(Wireless Mesh Route Protocol) was proposed which extended the flat routing to the class routing architecture like the ip routing architecture in data link layer. Through the network simulation and performance evaluation, the result shows that the WMRP has advantages in performance over the HWMP. The efficiency and expansibility of routing protocol are improved greatly.
