| Abstract(in English) | To improve the performance of an RSSI-based location estimation method, we have so far proposed area layout-based maximum a posterirori (MAP) location estimation method for a stationary target. For the MAP location estimation, we have derived the priori probability density function of a target location, and shown the improvement of the estimation accuracy by computer simulations, experiments and theoretical analyses. In this paper, we apply the area layout-based MAP estimation technique to the tracking problem of a moving target with an infinite impulse response (IIR) filter and a particle filter. The results of experiments demonstrate that the area layout-based MAP estimation technique can improve the location estimation performance for not only a stationary target but also a moving target. Furthermore, our experiments show that the MAP location tracking with the IIR filter outperforms that with the particle filter in terms of estimation accuracy and computational complexity. |
