Global Positioning System (GPS) is the main technology that plays an important role in satellite navigation. The main purpose of GPS is to determine the position or coordinate of an object based on location, time and speed which provide Location Based Services .But GPS cannot be used for tracking and navigation of indoor locations. So in this paper we proposed a solution to find indoor location along with relevant information of particular location. In this paper, percentage of signal strengths obtained from Wi-Fi analyzer in a smartphone were converted into distance between users and each AP. A user’s indoor position could then be determined using a formula proposed based on trilateration technique. The solution proposed is with respect to the context of a mall.
