In a Wireless sensor network (WSN), communication of the gathered data in the network from the nodes to the base station is a prominent activity and this communication of data consumes the maximum amount of energy. When there is a constant flow of information from the nodes to the base station in a wireless sensor network, the energy of the nodes gets drained due to limited battery resources of a sensor node. This directly affects the lifetime of the entire network. So our aim is to devise a routing protocol which will minimize the energy consumption and hence result in achieving extended lifetime of the entire sensor network. In this paper, we propose the Hop PEGASIS approach. The proposed Hop PEGASIS approach is more efficient than the LEACH, PEGASIS and Hierarchical PEGASIS protocols. Therefore, we focus on the concept of energy conservation which is a important factor and a major challenge in the design of Wireless sensor networks. We have used MATLAB environment for simulation.
