LEACH路由协议的改进

提出了一种节点密度和剩余能量传感器网络加权分群算法，通过设定权值。将节点的密度和剩余能量考虑在内，保证综合性能最好的节点成为群首。再通过控制群首发射功率使群内节点密度控制在合理范围内。该分群算法优化了群首选择，均衡了网络节点的能量消耗，延长了网络的生命周期。最后通过仿真验证该分群算法的性能。

Improvement of LEACH Routing Protocols

This article proposes a weighted group algorithm of sensor network which considers density and residual energy of the node．By choosing the best weighted value，it ensures that the best performance node becomes the header．The density of nodes in each group is within a reasonable scope through controlling transmitting power of the node．The improved group algorithm optimizes header choosing，balances the energy consumption of the whole network and prolongs the lifetime of the network．Finally，the simulation verifies the effect of the group algorithm．
