AbstractPrior to wide deployment of Vehicular Ad-Hoc Networks (VANETs) in public motorways, amongst the key challenges that must be adequately resolved is safety message dissemination reliability in the presence of error-prone wireless channel, propagation delays, extremely dynamic network topology, frequent network fragmentation and high vehicle mobility. In this paper, we investigate the application of network coding concept to achieve improved message dissemination reliability as well as increased bandwidth efficiency for efficient vehicular communication system. In particular, we proposed an efficient error recovery scheme which employs network coding concept to increase safety message broadcast reliability with a minimized number of encoded packet retransmissions. The benefits of the proposed scheme over simple error correction based on retransmission are clearly shown with detailed theoretical analysis and further validated with simulation experiments.
