Abstract: A network with reliable and rapid communication is critical for urban Vehicular Ad Hoc Networks (VANETs). VANETs consisting of vehicular nodes moving on the roads with wireless communication. However, the highly dynamic topology of VANETs and limited communication of performance have brought great challenges to the routing design of VANETs. It is difficult for existing routing protocols for VANETs to adapt the high dynamics of VANETs. Moreover, few of existing routing protocols simultaneously meet the requirement of high packet delivery and low delay in Intelligent Transportation Systems (ITSs). This paper proposes a novel Q-learning based routing algorithm under next-hop selection optimization of geographic routing protocol. To adopt the decision making on the next-hop selection algorithms, an off-policy algorithm as it learns an optimal action maximize Q value based on a reward function that estimates a link reliability between nodes in the routing decision process to select the more reliable next-hop. The performance of the proposed routing approach is evaluated using comprehensive network simulation. Simulation results show that the proposed algorithm can provide higher packet arrival ratio, lower delay than existing routing protocols.
