Message Based Communication Framework for Public Transportation Systems

The advancement of internet technologies has made it easier for local devices to access the internet. Smart systems are also becoming widespread in transportation systems. Device management using standard protocols becomes important for transportation systems; mainly responsible for vehicle tracking, in-vehicle sensor tracking and trip management. The presence of different solution providers in these systems makes it difficult for applications to work together and to manage in interaction with each other. This complexity can be managed by using loT approaches. In our study, we provide a message-based topic structure for device management problems. Pub/Sub and event driven framework was realized with the help of frequently used loT tools MQTT and WebSocket protocols. © 2021 IEEE
