Location Based Network Surveillance System for Shops and Malls

Wi-Fi is an emerging and low cost technology in the present scenario for finding the location inside the buildings, shops, malls, organizations, airports, etc. In this paper we develop location based network surveillance system inside organizations. The experimental results show that the RF Finger-printing method is more accurate as compared to the triangulation method by calibration and taking the grid size small. We also compare both the results and come to a conclusion that our system gives almost 2m error practically which is very less as compared to +5 or -5m given in [1]. To improve security in such areas is basic aim of our project. Our system will track location of all nodes which are trying to access the internet. And further it will keep track of all activities done by nodes within the network.
