摘要：GPS (geo-graphical positioning system) technology is used for navigation and positioning of the user. Ithelps users to navigate through maps but this concept faces problem when there are obstructions due to buildings and isalmost useless for navigating in an indoor environment. Many other techniques involve the use of external sensors andRFID’s that can be installed or can be carried around along with the user. But all this techniques involve devices whichare either not cost effective or creates problem in case of device failure. . By using the concept of WI-FI triangulationmethod for the purpose of localization of a user inside a building like mall, campus, hospital etc. this problem can beovercome. WIFI are nowadays already installed, for example in a shopping mall there are various outlets and all theseconsist of WIFI inside them. By developing a system that uses these WIFI routers for localization of user and guidingthem through the premises by downloading a map from server via a shortest path. Users can save location, browseoffers and events of various outlets through a smartphone
