Survey on Localization of Smartphone User in an Indoor Environment Using WIFI and Navigation through Layout of the Floor Plans
GPS (geo-graphical positioning system) technology is used for navigation and positioning of the user. It helps users to navigate through maps but this concept faces problem when there are obstructions due to buildings and is almost useless for navigating in an indoor environment. Many other techniques involve the use of external sensors and RFID’s that can be installed or can be carried around along with the user. But all this techniques involve devices which are either not cost effective or creates problem in case of device failure. . By using the concept of WI-FI triangulation method for the purpose of localization of a user inside a building like mall, campus, hospital etc. this problem can be overcome. WIFI are nowadays already installed, for example in a shopping mall there are various outlets and all these consist of WIFI inside them. By developing a system that uses these WIFI routers for localization of user and guiding them through the premises by downloading a map from server via a shortest path. Users can save location, browse offers and events of various outlets through a smartphone.
