Bus-based WSMP Dissemination Protocol for Vehicular Network.

Recently, there is a huge attention that given to the field of service discovery protocols in vehicular networks (SDPs). In the research community, there are a lot of (SDPs) that were designed for wired networks, mobile ad hoc networks and mesh networks. In addition, few studies have been conducted in service discovery protocols for vehicular ad hoc networks (VANETs). Therefore, this paper review the related works in this filed and provides the main design issues that should be considered when designing such protocols. This paper also propose a Bus-based WSMP (WAVE Short Messages) dissemination approach. To implement this approach a realistic mobility model is built using bi-directional coupled technique. The performance Bus-based proposed model is evaluated in order to design an efficient algorithm for service discovery protocol that utilizes the public bus networks. The results of the realistic simulation model are compared with mathematical framework. It is shown that the bus outperforms other vehicles in beacon delivering ratio. Therefore, the idea of using public buses in addition to the beaconing approach can be used in future work for designing efficient algorithms in the field of vehicular networks.
