Indoor Location Based Services using WiFi

The outdoor positioning system using GPS is well established and has been adopted throughout the world. We have various applications on our smartphones like Google Maps Navigation where we can easily find a pathway to our destination or find nearby restaurants, tourist attractions and many more. However, indoor positioning system is not so well established. Research work are going on, but bringing out its pragmatic nature has not yet got success on a large scale. At few places, indoor navigation system has been deployed but it is limited to private use. It is not yet made public because of the complexities involved in it. This project aims at making the indoor counterpart go public like that of outdoor positioning system by using Wi-Fi access points. Wi-Fi access points are easily available in colleges, office buildings, airports, metro stations and various other public places. To exploit the infrastructure and cost effective nature of Wi-Fi technology, we have devised a methodology to establish positioning system inside a public place. The availability of efficient mobile devices has paved the way for location based services and applications in internet domain.
