Wireless sensor network is a network of spatially distributed nodes to monitor certain application specific data. It consists of large number of sensor nodes with one or more base stations. The data is communicated from sensor nodes to the base station either directly or in multihop fashion. Routing is a key challenge in sensor networks, because nodes in the networks are constrained by energy, processing power, and memory. Such motivation drives motivation to design energy efficient routing protocols for sensor networks to prolong network lifetime. In this study i proposed a new multihop routing algorithm named energy efficient protocol using ring zone model (EEPRM). The protocol is simple and does routing decisions based on remaining energy of nodes, and does location based routing without the need for the nodes to know their positions.Simulation-based evaluation of EEPRM in OMNET++ conducted and the protocol is compared against well known protocols including An Address Light Integrated MAC and Routing Protocol for WSN,Flooding and AODV.Simulation results show that EEPRM outperforms AIMRP, AODV, and Flooding in terms of end to end delay, average hop count, and energy efficiency.
