在大型的传感器网络中分簇起着十分重要的作用,WSN节点由簇来组成,簇头节点将数据进行融合,数据的传输量得到了有效的降低,节点之间的通信开销减少,在网络中生存的时间得以延长。簇头节点在分簇算法中承担了比较重要的任务,与普通成员节点相比,簇头节点承担的工作任务更多,在大多数文献的分簇算法里为了使簇头节点不会因负载过重而能量过早耗尽,都给出了簇头选择的不同策略。
Clustering in a large sensor network plays a very important role. WSN nodes are composed of clusters. Fusion of data by cluster head nodes reduces the amount of data transmission and reduces the communication overhead between nodes. In the survival of the time to be extended. The cluster head node takes more important tasks in the clustering algorithm. Compared with the ordinary member nodes, the cluster head node undertakes more tasks. In most literature clustering algorithms, in order to make the cluster head node not load Overweight and premature depletion of energy, are given a different choice of cluster head strategy.
