摘要: 为实现网状(mesh)网在无线个人区域网(WPAN)中的应用,设计了一种基于WPAN mesh网络的二层路由协议算法。该算法引入“次优路由”和“二层路由”路由优化策略,进一步给出报文格式、路由协议模型及其模拟实现,并对协议进行性能分析比较。实验结果表明,该算法有效减小了路由的端到端跳数,较好地提高了报文发送比率和端到端通信效率。

Abstract: To realize mesh application in Wireless Personal Area Network(WPAN),a two level routing protocol based on WPAN mesh network is proposed.The TLMR protocol uses some optimization mechanisms including “near-optimal routing” and “two level routing”.Furthermore,packet format,routing modules and their simulation are described in details.Finally,it is compared with several other typical protocols.The experiment results show that the end-to-end hop counts are effectively decreased.The packet delivery ratio and end-to-end communication efficiency are also greatly improved.
