Wireless sensor network has so many applications like in military and civil. Wireless sensor network is made by thousands of tiny and low cost sensor nodes. Sensor nodes work on the battery power, and battery power is limited; that is why our main aim is to reduce battery power. Leach is the one of the hierarchy routing protocols for the energy saving for wireless sensor network. In this paper, we present the proposed work on a new approach. This approach saves the energy of the network and reduces the consumed energy of the node using these three parameters: energy parameter, vicinity and adding a vice-cluster head to each node and cluster for the back-up mode condition. Keywords: WSN, LEACH protocol, vicinity, vice cluster head, network life timeCite this Article Thakur Pradyumansinhji C, Joshi Jignesh H.
