Abstract
Vehicular Ad-hoc Networks (VANET) has attracted a great deal of attention during the last decade. This type of wireless network is predicted to play a key role in future automotive innovation. VANET as a foundation for Intelligent Transportation System (ITS) promises many improvements in terms of safety, resource efficiency - including traffic efficiency and congestion avoidance - and driver and passenger assistance services. Among these three main categories, safety applications are the most important, because they deal with the lives of large numbers of people who drive every day. Safety applications are classified as real-time applications; they must act with high level of confidence and within a certain period of time - otherwise their deployment doesn’t make sense. Consequently, Quality of Service (QoS) provisioning must be taken into account. Various methods of improving QoS in the different layers of VANET, such as physical and Medium Access Control (MAC) have been proposed so far. However, in this project the main focus will be the network layer. Two important routing protocols, Ad- hoc Ondemand Distance Vector (AODV) and Destination-Sequenced Distance Vector (DSDV) are compared regarding their QoS parameters including delay, packet loss, and overhead in simulation scenarios.
