“Internet of Things” means the interconnection of things – a person, buildings, vehicles, electrical and electronic devices, mechanical devices and so on. There are huge applications in this area like smart home, smart city, medical applications, Traffic management system etc. Now a day’s traffic congestion is a major problem which leads to the traffic jam in developing countries like India. Reaching the destination within the city limit is so unpredictable. It is necessary to analyze the traffic pattern in near real time. So it is necessary to develop an IoT based application with real-time data analysis to overcome the problem. In this paper, we present “saraNi – An IoT based pathfinder” is an application that is targeted to help daily commuters in reaching the destination from the source in the shortest and the fastest possible route. The application is indented to help the commuters using smart wireless sensor network. The application uses sensors that are placed in various junctions, which detects the congestions at the junction.
