The Vehicular Ad hoc Network (VANET) is a new technology and a key component of the Intelligent Transportation Systems (ITS) architecture that aims at promoting road safety, and providing more entertainment facilities on the road. VANET has received recently great attention from industry, academia and national government agencies. Recent research efforts have placed a strong emphasis on novel VANET design architectures and implementations. Despite many studies on VANETs, most of them focused on discriminating the nodes� mobility environment, i.e., nodes in VANETs are vehicles moving on roads surrounded by obstacles and at higher speeds than that in many other types of MANETs. This distinctive mobility environment makes designing efficient routing protocol a very challenging task. Recently, there has been more interest in using road side units RSUs not only to provide services but also to support routing with the aim of enhancing scalability and mitigating the overhead of the additional requirement a location service places on geographic routing. Despite many studies on the infrastructure-assisted routing protocols found in the literature, this routing strategy is still in its infancy. These available solutions suffer from low readability and deficiency in dealing with both vehicle-to-vehicle (V2V) communications and vehicle-to-infrastructure (V2I) communications. In an attempt to fill in this gap, in this presentation, novel routing protocols within smart city platforms, will be introduced and discussed. These protocols integrate both features of reactive and proactive routing schemes. They maintain proactive routes towards RSUs while they reactively seek for other nearby nodes in the network.
