An improved leach protocol for indoor wireless sensor networks

This paper proposed a EELP (Energy Efficient LEACH Protocol) routing protocol based on LEACH. LEACH (Low Energy Adaptive Clustering Hierarchy) is seminal work in the area of clustering-based protocol, proposed by W.B. Heinzelman. In EELP, all nodes are organized sequentially in the rooms of the apartments of a multi-story building. In this protocol, cluster head (CH) selection is determined as the highest energy by the base station. Simulation results demonstrated that our protocol is more energy-efficient than the LEACH protocol.
