[0046] The vehicle ad hoc network, referred to as the vehicle network, can not only improve the safety of vehicles by disseminating traffic safety information, but also provide good support for the distribution of entertainment information such as video, audio, and data files. It has become a new type of wireless data distribution network. Research hotspots. However, due to the rapid movement of nodes in the vehicular network and the frequent interruption of connections between nodes, an efficient data distribution mechanism is urgently needed to support the development of these vehicular network applications. Performance, in the vehicular network communication technology, the nature of the wireless broadcast channel provides a good means of propagation for the implementation of network coding, so network coding technology is naturally introduced to improve and enhance the performance of data distribution. On the other hand, the current network coding used in the vehicle netwo...
