摘要：Wireless sensor networks (WSNs) is one of the emerging field of research in recent era of communication world. These networks collect information from the environments and deliver the same to the applications to determine characteristics of the environment or detect an event. Since the sensor nodes have limited amount of energy, it is a major issue in wireless sensor networks to develop an energy-efficient routing protocol. Many energy efficient routing protocols have been proposed to solve this problem and increase the lifetime of the network. This paper proposes an energy efficient hierarchical based routing protocol. In this, clusters are made based on their geographical location & cluster heads are chosen on the basis of highest residual energy within the cluster as well as minimum distance to the base station from the cluster heads. Simulation is done using MATLAB. The results show that the network lifetime & residual energy of the nodes increases as we increase the number of cluster in the network
