This thesis proposes multi-components of Gaussian model to get much close description for the received signal strength. Also, this thesis adopts Excitor to approach a 99% exactly positioning for some specific field application such as surveillance desired application. In addition, this thesis presents a smoothing filter to adjust the moving path therefore the movement path shown in computer graphical interface may looks fluently, in addition, RSSI filter also improve position accuracy.

The results show that the system can keep certain smoothness with short delay, but the control precision can decline with the accretion of time delay, long random delay will not only reduce system expeditiousness, but also the smoothness and control precision at the same time. If the random delay is long enough, it can destroy the stability of networked control systems.

研究结果表明：系统在较小的延时下仍能保持一定的稳定，随着延时的增大，系统的控制精度有所降低；而较大的随机延时不但降低系统的总体快速性，同时，使系统的稳定性和控制精度明显降低，而当随机延时大到一定程度时，系统的稳定性难以保证。
