Abstract

Wireless sensor networks are composed of hundreds or even thousands of sensor nodes which have limited energy. Energy consideration is a very critical issue for designing routing protocols. This paper discusses a common clustering protocol, called LEACH, and improves cluster-head selection criteria. LEACH selects cluster-heads based on random probability, while the proposed algorithm considers the sensor nodes residual energy in order to balance energy dissipation among all of the nodes to extend network lifetime as one unit to minimize dead-spots. MATLAB simulation shows that the proposed energy consideration protocol which is called Percentage LEACH (PR-LEACH), provides better performance compared to LEACH protocol.
