By the reason of the node energy in wireless sensor networks is limited, energy-efficient routing algorithm must be designed to prolong the network lifetime. The paper proposes one new algorithm (MH-LEACH) based on classical Low Energy Adaptive Clustering Hierarchy (LEACH). It selects cluster head with taking into account the energy and multi-hop combined with simple hop in cluster. Simulation results show that compared to LEACH, MH-LEACH has better effect on prolonging the network lifetime and improving the energy utilization rate.
