适用于非平衡拓扑ZigBee网络地址分配与路由算法

Address Assignment and Routing Algorithm for Unbalanced ZigBee Network

分析了现有的ZigBee网络地址分配算法在非平衡拓扑下的不足,提出一种适用于该拓扑的混合式地址分配算法(Hybrid Address Assignment Mechanism,HAAM),并进一步设计了基于HAAM的路由方案(RB-HAAM,Routing Based on HAAM).经过OMNeT++仿真实验与其他有关地址分配和路由算法进行对比,结果表明,对于非平衡拓扑,在相同的仿真环境下,HAAM能够提高地址分配成功率,从而增加节点入网率,并降低地址分配过程的通信开销.RB-HAAM能够节省低能量节点能耗,有效延长网络生存时间,提高网络成功投递数据包总数.
