Fusion-based Sensor Placement for Target Detection with Guaranteed Accuracy Abstract:In sensor networks,sensor nodes collect local data and transfer these data to the base station often relayed by other nodes.Therefore sensor nodes that are nearer to the base station will consume more energy. If deploying sensor nodes in general way, i.e. deploying nodes uniformly in the network, sensor nodes nearby the base station will use up energy soon and the base station can t collect data anymore. This paper presents a density function to deploy sensor nodes through investigating energy consumption in wireless sensor network. Theoretical analysis and simulation result show that deploying by method of this paper improve system lifetime to times of deploying uniformly, where t is radio distance of sensor node and R is radius of the region of deploying sensor nodes.
