Abstract

Data gathering is the basic function of wireless sensor networks. Because the sensor nodes located near a base station have to relay data for a large part of the network and thus deplete their batteries very quickly, present base station movement strategies can realize network load-balance by mobile base station. Load-balance base station movement schemes are not available to improve network life unless the sensor nodes are distributed uniformly. Thus, the concept of point energy density is defined in this paper to represent the energy which every point used to sense environment, and an effective method for calculating point energy density is proposed. In this paper, an EDBBSM(energy-density-balance base station movement) strategy is proposed after analyzing the point energy density dissipation. Compared with the static base station scheme and the random base station movement scheme, EDBBSM can improve network life in every condition of sensor node distribution, and it is proved to be extensible.
