摘要:

针对无线传感网络中如何有效平衡节点的能量分布,文中在LEACH协议的基础上,提出了一种改进方法,在选取簇头时,考虑簇头在监测区域的平均分布,判断簇头间的距离,大于某一阈值,则确定簇头选取成功。同时将改进后的协议与原LEACH协议进行仿真比较,结果表明,改进后的协议可更有效地进行能量平衡,且到达了延长网络寿命的目的。

Abstract:

The paper puts forward an improved algorithm of the LEACH in wireless sensor network to effectively balance energy of nodes.Cluster heads are selected if the distance between cluster heads is greater than a certain threshold,since the cluster heads are distributed evenly in the monitoring area.Then a comparison is made of the improved algorithm of the LEACH with the LEACH in the aspect of energy consumption.Simulation results show that the improved algorithm of the LEACH is superior in balancing energy of nodes and extending the network life.
