An Energy Efficient Algrithm Based on LEACH Protocol
In this paper,we analyse the effectiveness of LEACH protocol in extending the lifetime for energyconstrained wireless sensor networks. An improved protocol LEACH-R is proposed based on LEACH protocol. LEACH-R improves the selection of cluster-head and proposes to choose relaying node compare to LEACH. Residual energy of the nodes is conisdered during selection of cluster-head,possibility of low-energy nodes being selected as cluster-head is reduced. Based on both residual energy and distance to base station,relaying node is chosen from cluster-heads to become the relay node between base station and other cluster-heads. The simulation result suggests LEACH-R protocol could balance network energy consumption and extend the network life cycle more effectively.
