摘要 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. A new topology control algorithm based on the clustering structure of the heterogeneous wireless sensor network is present.Through calculating the coverage density of each super node and confining the coverage density within certain limits,the algorithm can balance the coverage area of each cluster.Compared with LEACH(low energy adaptive clustering hierarchy),the algorithm gains a better performance on the variance of the coverage density and the path of the cluster.The results show that this algorithm has better performance on network lifetime prolonging and energy dissipation.
