摘要
ZigBee分布式地址分配机制影响网络地址资源的充分利用,且其节点参数配置不当会导致网络孤立点,使某些期望的连接被断开,造成一些部署设备的空置和网络连接率的降低。为了减免网络孤立点,提高网络连接率,本文提出了一种基于节点转移的ZigBee网络孤立点减免算法,设计了适用于转移算法的简洁命令帧,修改了ZigBee协议网络层帧控制部分,并对减免算法进行了模拟测试。模拟测试结果表明,该算法能够更有效地利用ZigBee网络地址资源,减少ZigBee网络孤立点,部署设备的网络连接率可提高7%～13%。
ZigBee distributed address assignment mechanism may affect the full utilization of address space, and if the ZigBee network configuration parameters are not proper, some network equipment can become isolated network nodes and the network connection rate decreases. In order to reduce isolated nodes and improve network connection ratio, this paper presents a new algorithm based on node-transporting. Simulation tests ware carried out. Test results show that the algorithm can promote the network connection rate about 7% --13% and makes use of Zigbee address resource effectively.
