Abstract :
In this paper, in order to achieve single target tracking in the wireless network, the original particle filter algorithm has been improved. I introduce the essence of the APIT algorithm about how to infer the particle position. Firstly, we determine the measured target position range. Secondly, we remove parts of the sample sets which have the great error. Thus, we can optimize the allocation of weights and improve the reliability of the weight so as to improve tracking accuracy and reduce the error effectively.
