| Notes | In Vehicular Ad-hoc Networks （VANETs）, due to the unstable network environment, the Road Side Unit （RSU） can not transmit data quickly, efficiently, and reliably to vehicles. This paper proposes a RSU multicast retransmission algorithm based on network coding technology. After the first stage of RSU multicasts, multiple vehicular communications characteristics such as location, speed, direction and data validity are considered jointly, and the optimal network coding combination can be found in an efficient way. By multicasting this network coded packet, the data dissemination efficiency can be enhanced. Experimental results show that, compared with the none-coding and random linear network coding data retransmission algorithms,the proposed algorithm achieves great performance improvements in VANETs data dissemination that the average data download rate is increased by 4 times,the average download latency is reduced by 90% and the data distribution delay is reduced by 40% and 20% respectively. 31-1289/TP Vehicul |
