摘　　要：为提高ZigBee网络的生存周期和数据传输的可靠性,研究人员在ZigBee网络原有路由算法的基础上做了许多改进。但是这些改进都只是单一考虑节点或者能量因素,没有考虑网络节点之间信道质量因素,这造成了因网络信道链路质量差引起的网络生存周期减少,网络传输可靠性降低等一系列问题。本文结合原有路由算法和相关改进算法的不足,在某一改进算法的基础上引入信道链路质量LQI。改进后,路由算法不再单一包括节点或者能量因素,而是同时考虑节点能量和网络信道质量LQI两方面因素。试验模拟的结果表明,该算法能在相同条件下,比较传统的路由算法和相关改进,在网络生存周期和网络传输可靠性方面均有所提高。In order to improve the lifetime of ZigBee network and data transmission＇s reliability, researchers has done a lot of improvement based on the original ZigBee network routing algorithm. But these improvements just considered the single node or energy, without considering the channel quality factors between network nodes. This has resulted in a reduction of the network lifetime and transmission reliability and because of the poor network channel link quality. This paper combined with the shortage of original routing algorithms and related improved algorithm, introduced the channel link quality LQI on the basis of a improved algorithm. After improvements, the routing algorithm is not only including the node or energy factor, but also considering both node energy and channel quality LQI. The experimental simulation＇s result shows that under the same conditions, compared to the traditional routing algorithms and related improvements, this algorithm improved network＇s lifetime and transmission reliability.
