Wireless Sensor Networks (WSN) is different than the Cellular Networks as I mentioned earlier. A WSN is composed of a large number of sensor nodes that communicate using a wireless medium (air). The sensor nodes are deployed randomly in the envir

实现了传感器网络的拓扑控制，以循环的方式随机选择簇头节点，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。(The topology control of sensor network is realized, cluster head nodes are randomly selected in a cyclic way, and the energy load of the whole network is evenly distribu
