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.
The existing ZigBee network address allocation algorithm is analyzed under the unbalanced topology, a Hybrid Address Assignment Mechanism (HAAM) suitable for the topology is proposed and a HAAM-based routing scheme is further designed After OMNeT ++ simulation and other related address allocation and routing algorithms, the results show that, for the unbalanced topology, in the same simulation environment, HAAM can increase the success rate of address allocation, thereby increasing Node network access rate and reduce the communication overhead of the address allocation process.RB-HAAM can save energy consumption of low-energy nodes, effectively prolong network lifetime and improve the total number of network successful delivery packets.
