Smart and Reliable Transportation System based on Message Queuing Telemetry Transport Protocol

With the advancement of IoT, the traditional transportation system be wrap up with intelligence to provide smart and quick services to user and be better informed on road safety and make safer and coordinated transportation medium. This intelligent transportation system ITS uses wired and wireless connectivity to communicate among objects connected. Whatever the application usage of ITS is, it's development require more reliable and invulnerable communication among the objects connected and have to be free from connectivity problems like service outrages, signal loss, bandwidth issues, problems of high latency and loss of data communication. Considering all this, this paper addresses the use of MQTT, a light weight messaging protocol in the message transfer of ITS application. The effectiveness of MQTT in ITS is illustrated by discussing different use case scenarios.
