Data Multi-hop Algorithm for Wireless Sensor Networks Based on LEACH Protocol

Nowadays, the LEACH algorithm which is commonly used in many protocols of WSN is a popular thing in the research fields. This paper proposes LEACH-ICM (LEACH-Inter Cluster Multi-hop) algorithm based on LEACH-ICE algorithm. The cluster head shall transfer data to the node which is closest to base-station and whose resident energy is available when its' resident energy is higher than limit energy. If all the nodes fail to accord with conditions, this cluster architecture will select new cluster head internally. By using this new data transfer way, LEACH-ICM balances the energy of the whole networks. Simulation results show that the algorithm achieves saving energy and extending the service life of the WSN.
