An Adaptive Routing Method for High-Speed-Road Scenario of the Internet of Vehicle[J]. Acta Electronica Sinica, 2020, 48(1): 172-179. DOI: 10.3969/j.issn.0372-2112.2020.01.021.
The high-speed mobility of the nodes makes the network topology change frequently
and the transmission path can be easily interrupted
so the routing efficiency is lower in Vehicular ad hoc network (VANET). We present an adaptive routing method for high-speed-road scenario of the Internet of Vehicle in this paper. This method uses Greedy Opportunity Forwarding (GOF) algorithm to find the optimal forwarding node when the next hop forwarding node is selected and it takes into account the distance calculation of the destination node
the link state between the nodes and the effective node degree of the next hop. We propose a new method to calculate the probability of connectivity. The simulation results and tests of the actual high-speed-road scenario show that our RAR method has good performance in the stability of routing
