An Adaptive Cluster-Heads Rotating Algorithm for the Clustering Routing in Wireless Sensor Networks

FENG Xiao;ZHANG Huidang;College of Information Science and Engineering,Henan University of Technology;  
In wireless sensor networks,clustering routing scheme is the main method for low energy routing design,and cluster-heads rotating algorithm is an effective way to balance the nodes energy consumption in clustering routing. However,few studies have been done on how to calculate cluster-heads rotating intervals. A cluster-heads rotating interval optimization algorithm is proposed based on the concept of cluster-tree working period,and the adaptive cluster-heads rotating mechanism is implemented. Meanwhile,in order to reduce the number of the cluster-heads,this paper proposes a clustering algorithm based on CDS( connected dominating set). In the simulation experiment,compared with four cluster-heads rotating strategies which have different fixed-length rotating intervals,the results show that the adaptive cluster-heads rotating algorithm has the longest network lifetime; compared with classical algorithms such as TopDisc and Guho,the results show that the CDS constructed by the proposed algorithm has the minimum size and diameter.
