实现无线传感器网络协议leach

该算法基本思想是：以循环的方式随机选择蔟首节点，将整个网络的能量负载平均分配到每个传感器节点中，从而达到降低网络能源消耗、提高网络整体生存时间的目的。仿真表明，与一般的平面多跳路由协议和静态分层算法相比，LEACH可以将网络生命周期延长15％。

-Realize wireless sensor network protocol leach basic idea of the algorithm is: a way to cycle randomly selected first cluster node, the energy of the entire network load evenly distributed to each sensor node in the network so as to achieve lower energy consumption, improve the overall survival time of network目的. Simulation shows that with the ordinary flat multi-hop routing protocol and static stratification algorithm, LEACH can extend network life-cycle 15.
