摘　　要：针对ZigBee网络运行过程中产生的孤立点问题,给出一种改善孤立点的入网算法。没有连接节点能力的父节点,通过选择算法选择出合适的转移节点,使父节点能够连接更多的孤立点;通过交换算法,进一步改善孤立点问题。仿真结果表明,在路由节点数量或终端节点数量一定的条件下,给出的入网算法从减少孤立点数量和提高网络连接率两方面均优于ZigBee连接方式和CIM算法,降低了分布式地址分配机制对孤立点的影响,使节点取得更好的连接效果。According to the problems about the isolated nodes that caused by the operation process of ZigBee networks, this paper proposed an improved network algorithm for isolated nodes. Firstly, father nodes, which were not able to connect nodes, chose shiftable nodes appropriately to connect more isolated nodes in the selection algorithm. Secondly, it could improve isola- ted nodes problems in the exchange algorithm. In a certain quantity of routers or end-devices, the results of simulation show that the improved network algorithm is superior to ZigBee protocol and CIM algorithms in decreasing isolated nodes and increas- ing the network connection rate. Besides, it can reduce the negative effects of the distributed address assignment mechanism of isolated nodes, and make the connection better.
