摘要
基于IEEE802.15.5的高速无线个域网(wireless personal area network,WPAN)Mesh网络中的基于服务器的路由算法(server routing,SR)在链路状态信息注册阶段和最优路径建立阶段均存在冗余的开销和操作。提出一种高效率低时延的路由算法(high-efficiency and low-delay routing algorithm,HLRA)。在HLRA算法中引入了广播链路状态注册消息机制和缩短中继列表长度机制,从而利于更快速地建立最优路。理论分析和仿真结果表明,与SR算法相比,HLRA算法在保持包的投递率不变的前提下,减小了网络开销,降低了平均端到端时延。
Server Routing（SR） in high rate IEEE 802.15.5-based WPAN Mesh has redundant overhead and operations in the link state registration and route establishment stages of SR.A high-efficiency and low-delay routing algorithm（HLRA） was proposed.Two new mechanisms which are the broadcasting Link State Registration commands and decreasing the length of relay list in retransmission were introduced to improve the speed of building the route.Theoretical analysis and simulation results show that the network overhead and the average end-to-end delay were reduced in HLRA and the packet delivery ratio was almost kept unchanged.
