摘要： 基于LEACH协议，提出助理簇头分簇算法。该算法能在无线传感器网络中根据簇头节点所处的地理位置、剩余能量及簇内成员节点数目，动态决定是否需要在簇内产生助理簇头，并在需要产生助理簇头的簇内选择合适的节点，从而减少簇头通信能耗，同时解决某些簇头与基站的通信问题。仿真结果表明，该算法能有效降低网络能耗、延长网络生存时间。

Abstract: On the basis of LEACH, this paper proposes an assistant cluster head clustering algorithm. In Wireless Sensor Network(WSN), according to the cluster head node’s geographical location, remaining members of the cluster energy and the number of nodes in the cluster, the algorithm can dynamically determine whether to generate assistant cluster head and choose appropriate nodes in it, thus reducing the energy consumption of cluster head communication, while addressing some of the cluster head and base station communications. Simulation results show that this algorithm can effectively reduce the energy consumption, and extend the network lifetime.
