Clustering algorithm for WSN based on distance-energy and master-vice cluster head

For large scale sensor network,the life is very important for the performance of network.Aimed at how to prolong the life of sensor network,a new clustering algorithm based on distance-energy and master-vice cluster head is proposed.Voronoi polygon is used to realize the adaptive clustering based on the distribution of nodes and gain balance clusters.In order to balance the distribution of energy,distance-energy level is proposed as the basis of cluster head rotation in cluster area.Master-vice cluster head is proposed to avoid "fake death" and prolongs the life of network.Theoretic analysis and simulation results prove that the mechanism can prolong the life of network effectively,and gain much more data.
