Aiming at the problem that the energy load of wireless sensor networks（WSNs） is unbalanced

a clustering optimization strategy based on OCBC is proposed

in order to extend the life cycle and improve energy efficiency.Divide the network with longitudes and latitudes and elect cluster-head according to the geographic position and dump energy of the nodes.Non-cluster-head nodes join cluster-head choose smaller distance and larger energy cluster-head to build clusters.Simulation results indicate that the strategy effectivenely improve energy consumption balance and extend life of the network.
