摘要
提出基于邻居表的Zig Bee网络路由新算法,在路由节点中构建邻居表,当路由节点转发数据时,通过邻居表中的信息建立路由,尽可能地通过持续电源路由节点转发数据,以减少电池供电路由节点的能量损耗,延长网络的生存时间;同时改进了现有树路由协议,使之能够兼容新的算法。理论和仿真分析表明:所提算法能够有效降低电池供电节点的能量损耗,其性能优于分布式地址分配机制(DAAM)。
A new algorithm of Zig Bee network routing based on neighbor table is proposed,which is built in routing nodes,when routing nodes is forwarding data packet,establish routing through information of the neighbor table,as much as possible by continuous power supply routing nodes forward data and in order to reduce energy loss of battery-powered routing nodes,hence extend network lifetime.Meanwhile,the present tree routing protocol is improved to compatable with the new algorithm.Theoretical and simulation analysis show that the proposed algorithm outperforms DAAM in effectively reducing energy loss of battery-powered routing nodes.
