A smartphone based indoor navigation system

Although various solutions have been suggested for indoor navigation systems, most methods require the support of external physical hardware infrastructure. Due to the increase in complexity and cost of set-up of supporting hardware requirements, scalability will always be an issue with such systems. In this paper, we present the design of a smartphone based indoor navigation system. The proposed method uses on-device sensors for Dead-reckoning and is supported by a web based architecture, for easily creating indoor maps and providing an indoor location's information for navigation and localization. The system has been implemented and tested, and the results indicate that the approach is useful for navigation in indoor environments.
