摘　　要：针对低能量自适应聚类路由算法(LEACH)存在节点能量消耗过快和生存时间短的缺点,提出了一种能量异构自适应成簇路由算法,该算法对簇头选择阈值进行了改进,使能量高、与基站距离近的节点优先选为簇头。通过仿真比较了两种算法的性能,发现采用本算法后无线传感网络的生命周期有效提高,一个生命周期内数据传输总量也明显增长。通过实验表明温湿度采集系统具有较低误差率和较高的数据传输准确性。In order to overcome the shortcomings of excessive energy consumption and short survival time of low-energy adaptive clustering hierarchy （LEACH）,this paper proposes an energy heterogeneous adaptive clustering routing algorithm,which can improve the cluster head selection threshold and the node with high energy and close proximity to the base station is preferentially selected as the cluster head.The performances of this algorithm and the original one are compared by simulation.It is found that the life cycle of the wireless sensor network is effectively improved by using this algorithm,and the total amount of data transmission in a life cycle is obviously increasing.Experiments show that the temperature and humidity collection system have lower error rate and higher data transmission accuracy by adopting the new algorithm.
