Message oriented middleware (MOM) refers to the software infrastructure supporting sending and receiving messages between distributed systems. AMQP MQTT are two most relevant protocols in this context. They extensively used for exchanging since they provide an abstraction of different participating system entities, alleviating their coordination simplifying communication programming details. These protocols, however, have not been thoroughly tested context mobile or dynamic networks like...

Currently, the number of vehicles increases every year, raising probability having accidents. When an accident occurs, wireless technologies enable to share warning messages with other by using vehicle (V2V) communications, and emergency services infrastructure (V2I) communications.
