Energy-efficient distance based clustering routing scheme for long-term lifetime of multi-hop wireless sensor networks

Abstract

To balance energy consumption among cluster-heads in multi-hop wireless sensor networks, we propose an energy-efficient distance based probabilistic clustering scheme. Our scheme considers a distance from the sink(base station) to each node as well as the residual energy of each node as the criterion of cluster-head election. Through simulation experiments, we show that our scheme is more effective than LEACH and EEUC in prolonging the lifespan of multi-hop wireless sensor networks. © Springer-Verlag Berlin Heidelberg 2007.
