A Service Discovery Protocol for Vehicular Ad Hoc Networks: A Proof of Correctness

Recently, vehicle networks are gaining great deal of attention from the research community. In order to provide efficient and pervasive road communication, Next Generation Vehicular Networks (NVN) are considered a promising solution. NVNs have unique characteristics and face challenging problems. Consequently, it is hard to use the traditional mechanisms and protocols in this type of network. Service discovery is a very challenging problem for NVN-based applications. Furthermore, to the best of our knowledge, very little work has been done to deal with the service discovery problem in NVNs. Due to the high mobility and density of vehicles, traditional discovery techniques do not perform well. To solve this problem, we propose a novel class of service discovery protocol that would allow vehicles to discover services through the vehicular wireless network. Our hybrid proposed technique combines both proactive and reactive discovery approaches. It is also adaptive because it adapts to the vehicular network conditions, thus enabling efficient discovery characterized by low overhead and a high success rate. In this paper, we present the proof of correctness and the message and time complexities computation of our protocol.
