摘要： 研究LEACH和PEGASIS协议，提出一种无线传感器网络中的助理簇头分簇算法。该算法根据簇头节点的地理位置、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，以减少簇头通信的能量消耗。实验结果表明，加入助理簇头后，原算法在均衡性能、能量消耗和网络生命周期等方面均得到优化。

Abstract: Based on LEACH and PEGASIS algorithm, this paper proposes an assistant cluster head algorithm in Wireless Sensor Networks(WSN). It according to geographical location of the cluster head node, residual energy and the number of cluster member nodes, determines whether production assistant in the cluster head and cluster head needs to generate assistant, and chooses the right node cluster to reduce the energy consumption of cluster head communication. Assistant in PEGASIS adding cluster head, the improved assistant cluster head algorithm’s performances are improved compared to existing algorithms, in equilibrium and energy conservation, to extend the network life cycle played a positive role in terms.
