Network coding is an emerging technique known to improve the network performance in many aspects. In Vehicular Ad-hoc NETwork (VANET), the bandwidth is considered to be one of the most important network resources. In this paper, they propose a network coding technique to improve the bandwidth utilization for non-safety applications in VANET. In a scenario where there are two sources broadcasting the data into the same area at the same time, the relay will use the network coding technique to decrease the number of rebroadcasting events and the consumption of the bandwidth, However, a fundamental problem for the relay when it receives a packet, is whether to wait for a coding opportunity and save the bandwidth or send the packet directly and reduce the delay.
