This paper considers the nodes with less energy becoming the cluster heads and setting up new clusters every round, these cause the problem that the nodes consume their power quickly and the energy efficiency decreases. By the method of network average energy and cluster heads selection based on Voronoi cell, the protocol of LEACH-V balances the consuming of network's energy and prolongs the network's lifetime. Compared with LEACH, the simulation results indicate that LEACH-V protocol extends the lifetime of network, delays the first node's death time, and enhances the energy efficiency.%针对LEACH协议中网络能量不平衡和利用率低的问题,提出一种改进协议(LEACH-V),在计算阈值时引入剩余能量与网络平均能量,并基于Voronoi图单元进行簇头选择.仿真实验结果表明,LEACH-V协议能延长网络寿命,推迟第1个死亡节点出现的时间,提高能量利用率.
