New Reliable Self-Adaptive Routing Protocol for Vehicular Ad Hoc Network

In order to effectively predict reliability of the link between two vehicles of VANETs (Vehicular ad hoc networks) and design a reliable routing protocol to satisfy various applications requirements, we analyze the details about motion characteristics of the vehicle and the reasons that cause links disconnect in this paper. We evaluate the reliability of links and introduce it as an important parameter to design a novel routing protocol. The Q-Learning algorithm is used to dynamically adjust the routing path through interaction with the surrounding environment. Based on these, a new reliable self-adaptive routing protocol (RSAR) is proposed. The experimental results show that the performance of RSAR protocol is very good on delivery rate and delay.
