Vehicular Ad hoc Network: Flooding and Routing Protocols for Safety & Management Applications

Vehicular Adhoc Network (VANET) is one of the key technologies in an Intelligent Transportation System (ITS) to address issues regarding traffic management and road safety, traffic control and re-routing. Due to an increase in the number of vehicles, high bandwidth requirements for applications, and highly dynamic topology, VANET requires special attention for data dissemination procedures known as flooding and routing for reliable in-time data delivery. This study proposes a hybrid flooding mechanism to provide an efficient and reliable data delivery. In this dissertation, an adaptive protocol is proposed by combining the functionality of topology and position-based routing. Since route maintaining and recovery mechanisms add delays to the routing procedure, this study considers the reorientation of routing at the lower layer. The proposed routing protocols are implemented in the Veins framework and provides efficiency in term of in-time data delivery.
