Evaluation of LEACH Protocol Subject to Different Traffic Models

Abstract

Different traffic models are introduced to LEACH protocol for wireless sensor network. Network performance of LEACH with these traffic models is analyzed. Our results provide design guidelines for LEACH implementation under a realistic traffic model in which each node has a range of transmission probabilities and for a range of network sizes. Furthermore, by incorporating realistic energy model from Crossbow MICA2 motes, our simulation results also show that LEACH has promising performance when implemented with Crossbow MICA2 motes.
