LoRaWAN based GPS tracking of city-buses for smart public transport system

The increasing level of air-pollution due to vehicular emissions is an imminent threat to our environment. In order to tackle this situation, we need to promote and adapt public transport. Making the existing city-bus system smarter by tracking the buses is the step that can be taken immediately for making public vehicles more accessible. The main hurdle in deploying traditional GPS trackers is the maintenance cost which can significantly be reduced by using LoRaWAN instead of GSM/GPRS modules. In this paper, an end-to-end wireless tracking system based on LoRaWAN is proposed. The gateway is set up along with server and data is stored in a cloud database. Android application is built to show the current location of the transmitter to the user. The main contribution of this paper is in building a custom gateway and server which provides more flexibility in designing the network parameters when compared to the commonly used third-party gateway or server applications.
