面向WSN的聚类头选举与维护协议的研究综述

Research Survey of Clustering Head Election and Maintenance Protocol for WSN

借助数据聚集和融合,分层聚类协议能有效减少网络的整体能耗,聚类创造分层的无线传感器网络,该类型的网络可以促进能源受限的节点有效利用能耗,从而扩展网络生命周期,减少系统的能耗以及提高整个系统的扩展性。聚类协议的关键在于聚类头的选举和维护,在综述WSN中2010~2018年发表的各类聚类协议的聚类头选举与维护算法,统计并分析其聚类特征、聚类目标,以及选取聚类头的考虑因素。

The hierarchical clustering is an efficient way to reduce the overall energy consumption within the cluster by performing aggregation and fusion of data. Clusters create hierarchical WSNs, which facilitate efficient utilization of limited resources of sensor nodes and thus extend network lifetime, reduce energy consumption of the system and provide overall system scalability. The most important part of clustering method is the cluster head election and maintenance. The proposed work of this paper is to provide an overview of the cluster head election and maintenance of hierarchical protocols which range from 2010 to 2018, and statistical analysis their clustering characteristic and clustering objective, also the factor of elect a cluster head.
