Abstract :
For the node localization of wireless sensor network, the cost of anchor nodes is very high. To reduce it, this paper adopts the idea of virtual anchor nodes, introduces the Gauss Marco´s mobile model to identify the movement trajectories of virtual anchor node, and then optimize it, so that the virtual anchor node can distribute uniformly in the region detected. Combining with the centroid localization algorithm, a high coverage rate, low energy consumption, low cost and fast localization algorithm can be achieved. The simulation results show that the technique proposed in this paper is effective, and the positioning error can meet most application requirements.
