提出一种基于异类传感器网络的分簇拓扑控制算法.该算法通过在成簇的过程中计算各个超节点的覆盖密度,控制节点的覆盖密度在合适的范围,使得各个簇的覆盖范围大致均衡.最后通过实例与传统的LEACH算法进行比较.结果表明,该算法在覆盖密度方差值和平均链路长度这2个性能指标上具有更好的优越性,可以更好地节约能耗和延长网络的生存周期. This paper proposes a clustering topology control algorithm based on heterogeneous sensor networks.This algorithm calculates the coverage density of each super node in the process of clustering and controls the coverage density of nodes in the appropriate range so that the coverage of each cluster is roughly balanced. Finally, an example is compared with the traditional LEACH algorithm.The results show that the proposed algorithm has better superiority in covering two performance indexes of density variance and average link length, which can better save energy and extend network Life cycle.
