Abstract

To solve the problem of the lifetime and the energy efficiency in wireless sensor networks,an energy efficient approach to improve the low enery adaptive clustering hierarchy(LEACH) named MHS-LEACH was proposed.The algorithm achieved the goal of energy efficiency by dividing sensing area into sectors and distributing cluster head IDs according to these sectors.The algorithm adjusted cluster heads according to the remaining energy of nodes,and distributed cluster head IDs according to virtual sectors,and looked for the father node of some cluster node among the cluster nodes in the same sector to build the tree link to the sink in order to achieve the multi-hops communication between the cluster nodes and the sink node.Experimental results indicate that compared with LEACH and ID-LEACH,MHS-LEACH not only prolongs the life time of the wireless sensor network efficiently,but also balances the energy consumption per round.
