无线传感器网络使用ZigBee技术默认的分布式地址分配机制(DAAM)为节点分配地址时没有考虑到网络拓扑结构的优化,造成了网络深度的浪费.为此,提出一种ZigBee网络分布式借地址分配(DBAA)算法,通过为节点分配两跳通信范围内的空闲地址优化网络拓扑,从而提高节点获得地址的成功率.理论分析和仿真结果表明:DBAA算法在地址分配成功率、平均通信开销和平均耗时方面性能优于DAAM和SLAR方案.%Wireless Sensor Network (WSN) adopts the default Distributed Address Assignment Mechanism (DAAM) of ZigBee technology to assign the addresses to the nodes without considering the optimization of the network topology, which causes the waste of network depth. In this paper, the authors proposed Distributed Borrowed Address Assignment (DBAA) algorithm to increase the success rate of joined nodes, which assigned the free addresses from 2-hops neighbors to the nodes for the optimization of the network topology. The theoretical analysis and simulation results show that DBAA algorithm outperforms both DAAM and Single Level Address Reorganization (SLAR) scheme in terms of the success rate of address assignment,communication overhead, and the average time of assigning addresses.
