Building gradient field is the important part of center aggregation algorithm in wireless sensor networks. It is found that flooding method using outward diffusion gradient will cause a serious problem of power consumption. In order to save energy in wireless sensor networks,the ant colony algorithm is applied to the building gradient field. Then a center aggregation method based on ant colony algorithm is proposed. Simulation results verify the feasibility of the method. The results show that the center aggregation method based on ant colony algorithm can significantly reduce the energy consumption of wireless sensor networks,and prolong the lifecycle of wireless sensor networks.
