An improved target tracking accuracy algorithm based on particle filtering in WMSN

In this paper, the theory of target tracking in wireless mobile sensor network is analyzed and basic particle filtering technology is discussed. To solve particle degradation problems, an improved particle filtering algorithm is given after modified the important density function and the resample technology. The improved particle filtering algorithm has better tracking accuracy than basic particle filtering after simulation, and can be used in places emphasis on tracking accuracy in wireless mobile sensor network.
