无线传感器网络中LEACH算法的改进研究

针对经典分簇路由算法LEACH在选取簇头时的不足,文中从节点区域能量平衡出发,尽量将剩余能量较高且所在位置覆盖密度较大的节点充当簇头,使整个区域"均匀"消耗能量,并基于此思想提出了一种对经典分簇路由算法LEACH的改进算法.实验仿真结果表明,改进算法能有效平衡区域能量消耗,延长网络的生命周期.

Research on Improved Algorithm of LEACH in Wireless Sensor Networks

This paper suggests an improved algorithm of LEACH, a classical cluster - based routing algorithm which has deficiency in selecting cluster heads, based on the balancing of regional energy. Take as much as possible nodes which have high remaining energy and set on the density covering area as heads in order to make the whole region's energy consumption to be average. Simulation results show that the improved routing algorithm balances the regional energy efficiently and achieves an obvious improvement on the network lifetime.
