Improved EEUC routing protocol for wireless sensor networks

After researching on LEACH and EEUC routing protocols of wireless sensor networks,according to problems existing in EEUC,such as not considering the number of selected final cluster head for the tentative cluster head selection,mainly considering the network energy consumption index for the next hop selection and wasting of energy for constructing cluster frequently,this paper proposes an improved-EEUC(I-EEUC).It uses the strategy of selecting cluster heads in LEACH to improve EEUC in selecting of tentative cluster heads and considers the network energy consumption index,residual energy and the number of members in the cluster to select the next hop.In order to save energy in transferring control information and not to reduce energy efficiency,it reconstructs cluster after every two data collections.The simulation results show that it permits the nodes alternately to be served as the final cluster heed,balances the energy consumption among nodes and prolongs the networks survival time effectively.
