说明：  是自己论文中编写的无线传感器网络中簇间路由分层次通讯方法的matlab仿真代码，可以直接出生存期图。很多论文都用这个思想。
(Matlab simulation, an improved version of the leach agreement between the clusters, the passing of a hierarchical routing protocol to send a message, many papers use this thought, just write and run directly displayed a life cycle)
