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 distributed to each sensor node, so as to reduce the energy consumption of the network and improve the overall survival time of the network.)
