An Extended Vice-Cluster Selection Approach to Improve V Leach Protocol in WSN

The paper presents a new version of leach protocol called Improved VLEACH which aims to increase network life time. In this paper we first completely analysed the typical clustering Routing Protocol-LEACH and its deficiencies and proposed improved v-leach. The work to be done in improved v-leach protocol on selection of vice cluster head. The Vice Cluster head is that alternate head that will work only when the cluster head will die. The process of vice cluster head selection on the basis of three factors i.e. Minimum distance, maximum residual energy, and minimum energy. The proposed approach will improve the network life as never the cluster head will die. As a cluster head will die it will be replaced by it's vice Cluster head. After a number of simulations, it was found that the new version of improved v-LEACH outperforms the original version of leach protocol by increasing the network life time 49.37%.
