Research of Routing Strategies Based on Network Encoding Under Vehicle Networking

Vehicular ad-hoc network (VANET) is a mobile Ad-hoc network composed of vehicles and roadside access points. It is a wireless network that enables information communication between vehicles and vehicles, between vehicles and access points. The vehicle-mounted network is different from the traditional wireless network, and has the characteristics of fast change of network topology, limited nodes, and intermittent connectivity of the network. Therefore, data transmission performance faces the challenges of low bandwidth utilization, large load, and high latency. In order to improve the efficiency of on-board network transmission and reduce the time delay, the network coding technology is proposed to significantly reduce the delay and improve the transmission efficiency. This paper summarizes the research on various routing strategies based on network coding in the VANET environment, and points out the future research directions through comparative analysis.
