Abstract: To ensure the efficient functioning of intelligent transportation systems, it's crucial to establish reliable communication channels with vehicles and roadside units. Vehicular ad hoc networks (VANETs) offer a brilliant solution for facilitating such communication among vehicles nodes and other units. However, due to the dynamic nature of VANETs characterized by high mobility and frequent topology changes, developing a dependable routing algorithm is a significant challenge. Given the vulnerability of communication links in VANETs to disconnection, ensuring routing reliability is paramount in these dynamic networks. This paper proposed a novel reliable model for VANET aimed at facilitating dependable path finding in VANETs. Central to our approach is the concept of link reliability, which represents the probability of maintaining a continuous operational link of communication among vehicles over a specific duration. We achieve precise computation of link reliability by leveraging vehicle location, velocity, and direction data along roadways. Our proposed dependable routing protocol, AODV-R, builds upon the widely-used ad hoc on-demand distance vector (AODV) routing protocol. Simulation results demonstrate that AODV-R, while reducing routing control overhead, outperforms the standard AODV protocol for enhanced delivery ratio and reduced link failures.
