Multihop Broadcast Protocol in Intermittently Connected Vehicular Networks

There are great challenges in vehicular networks, i.e., continuous connectivity cannot be guaranteed due to interruptions. This paper proposes a novel multihop broadcasting protocol with low signaling overhead in vehicular networks with frequent interruptions named as trinary partitioned black-burst-based broadcast protocol. The protocol operates without any infrastructure. It has low overhead supporting different quality of service levels. Both analysis and comprehensive simulations show that the proposed protocol outperforms the bench mark schemes.
