Namrata Arya, Vivek Suryawanshi . Distance based Cluster Head Selection Model for Optimum Number of Clusters in WSN. International Journal of Computer Applications. 156, 1 ( Dec 2016), 58-63. DOI=10.5120/ijca2016912362
Wireless sensor network is growing very much in last few decades as its useful applications. To provide more functionality it’s necessary to increase lifespan by clustering method. Clustering divides sensor nodes area into numbers of logical cluster. Each cluster has responsible node known as cluster head. This clustering and CH selection method uses lots of energy this energy can be saved by effective clustering method and improve lifespan of overall network. This work improves previous work for proper energy utilization for cluster head selection in WSN. Distance from base station is used for better clustering with optimum number of nodes within cluster. The nodes are categories into ring form with base station locate in center. A method with different probability of each node for cluster head selection is proposed. This probability of node select as cluster head is based on distance of current node from base station. The proposed method is reduces overall energy uses over other methods and performance is increased as numbers of nodes increases within large distance to base station
