摘要 基于最小生成树策略的数据汇集算法使得数据传输效率高,但是树的构造使得转发节点负载过高,能量消耗过大,还会造成无线传感器网络的负载不均衡。针对这种情况,提出一种考虑负载均衡的数据汇集算法,该算法基于最小代价树的建立策略,在构造树的过程中避开剩余能量小的节点,最大化无线传感器网络的生存时间。 Date-centrie algorithm based on minimal spanning tree improves the effective of date transmission,however,it makes the energy consumption of transmission nodes always high and lead to the unbalance load in WSN.Considering this,the paper presents an improved date-centric algorithm.The improved algorithm takes account of residual energy of nodes and avoids to use the less residual energy nodes and maximizes the lifetime of the whole network.
