Abstract : The Smartphone based Interactive Indoor Navigation System (SIINS) is an application that is used for localization and navigation in an indoor environment, in this specific case, an academic block of Amrita Vishwa Vidyapeetham and works completely offline. The main focus of this work is to develop an efficient and effective interactive indoor localization and navigation system that operates on smartphones solely via a Wi-fi network (intranet) with a text input query system. With the advent of Global Positioning System (GPS), mobile users have navigated from one place to another with the help of the internet. Although this is very useful, it drains battery and needs many background processes to function simultaneously. SIINS is an offline application which helps locate where an end system is in an indoor environment and helps navigate from a user’s current position to other places within the environment. Such an application is needed as GPS mostly does not function efficiently in an indoor environment. Our application is mainly divided into two modules; Localization and navigation. Naive Bayes, Support Vector Machine and Random Forest algorithms are used for tracking during localization phase and dijkstra’s algorithm is used for finding the shortest path.
