为了避免能量较少节点当选为群首而过早死亡，对Leach协议群首的选取进行改进。采用结合节点剩余能量重新设置阈值的方法，选取剩余能量较多的节点作为群首，解决了能量较少节点当选为群首和群首负担载过重的问题。仿真结果表明，采用改进后的算法可以有效减少网络能量的消耗，延长网络生存时间。

In order to avoid electing less energy nodes as cluster heads,which may cause premature death of these nodes, the selection of LEACH protocol cluster head is improved. The nodes with more residual energy are selected as cluster heads by the method of restting threshold according to their residual energy,the way of which avoids the nodes with less energy being elected as cluster heads and the cluster heads bearing overweight load. The simulation results show that the improved algorithm can effectively reduce the network energy consumption,and prolong the lifetime of the network.
