Executive Summary

In this paper, the authors evaluate the performance of a novel algorithm for tracking of a mobile node, interms of execution time and Root Mean Square Error (RMSE). Particle Filter algorithm is used to track the mobile node, however a new technique in particle filter algorithm is also proposed to reduce the execution time. The stationary points were calculated through trilateration and finally by averaging the number of points collected for a specific time, whereas tracking is done through trilateration as well as particle filter algorithm. Wi-Fi signal is used to get initial guess of the position of mobile node in x-y coordinates system. Commercially available software "Wireless Mon" was used to read the WiFi signal strength from the WiFi card.
