| 摘 要： | 以LEACH算法为基础,针对传感器节点能量消耗不均衡的问题,综合考虑剩余能量、与sink节点的距离、当选次数等因素,提出一种改进的簇头选择阈值公式。经仿真计算,改进后的算法有效地改善了节点能耗的均衡性,延长了网络的生存时间。

| Abstract: | A new threshold expression of cluster head option of LEACH in wireless sensor networks is given,which is based on residual energy,distance between the node and the sink node,and the times for cluster head.The simulation results show that the new arithmetic make a great progress in energy consumption balance and network’s lifetime. |
