摘　　要：针对分簇组网过程中节点能耗不均、能量利用效率低以及网络的生命周期较短等问题,面向具有随机异质特性的传感器网络,论文为解决该问题,提出了一种基于自适应簇半径的高效组网算法ARCN(Adaptive Radius Cluster-Networking algorithm)。随机异质节点以能量及可达邻居节点的密度作为簇首选举的标准;定义以能量和分环位置为指引的簇内架构,实现兼顾节点自身剩余能量和通信消耗能量下的择优入簇和传输路径。分布式的工作模式保证了簇首分布的均匀,数据中心Sink附近通信模式的调整,能避免能量塌陷。通过与其他3种异构化改进配置的分簇算法的性能对比,ARCN在能量利用率、节点和网络整体寿命的稳定性方面,均表现出较为明显的优势。In order to deal with the problems of the non-balanced energy consumption,low energy utilization efficiency and short lifetime in clustering process,an efficient clustering Adaptive Radius Cluster-Networking algorithm(ARCN)is proposed in the heterogeneous sensor network.Concretely,both the energy and the density of neighboring nodes are considered as the election terms for cluster header.Besides,taking into account the residual energy and the communication consumption,an intra-cluster architecture is able to be built based on the nodes’residual energy and their ring numbers,which can help node to join the best cluster and find the reasonable transmission path.The distributed schedule ensures cluster headers to be distributed evenly.The adjustable communication modes among headers nearby Sink avoid“energy holes”.Comparison with three improved heterogeneous clustering algorithms,ARCN exhibits obvious advantages in energy utilization,stability of nodes and overall network lifetime.
