Abstract�Network lifetime is the major constraint in the design of the wireless sensor network. Designing an energy efficient routing algorithm to increase the network lifetime is one of the most significant design criteria of wireless sensor networks. Various clustering techniques are used previously to augment the network lifetime. A novel routing protocol, Fixed Low Energy Clustering Hierarchy (FLECH) is proposed to achieve the increased gross lifetime of the wireless sensor network. FLECH is a hierarchical based routing that has fixed clusters and heterogeneous nodes. A cluster head is elected in each of the fixed clusters based on two attributes of nodes, energy and distance from the base station. As the event occurs the member nodes communicate the message to its respective clusters heads using Adaptive on Demand Distance Vector (AODV) algorithm. Then the cluster heads aggregate the received data and transmit it to the base station.
