Wireless sensor networks has come out as an important computing platform.A wireless sensor network is an aggregation of nodes organized into a cooperative network.Each node consists of processing capacity. Energy conservation and maximization of network lifetime are commonly recognized as a key challenge in the design and implementation of wireless sensor networks. In this paper, we propose an Enhanced Energy Efficient Chain-based Routing Protocol (EEECRP) for wireless sensor networks to minimize energy consumption and transmission delay.EEECRP organizes sensor nodes into a set of horizontal chains and a vertical chains. Chain heads are elected based on the residual energy of nodes and distance from the header of upper level. In each horizontal chain, sensor nodes transmit their data to their own chain head. EEECRP also adopts a chain-based data transmission mechanism for sending data packets from the chain heads to the base station. The simulation results shows that EECRP outperforms PEGASIS , ECCP and EECRP in terms of network lifetime, energy consumption.
