Destination Oriented Routing Protocol for VANETs

Abstract

Vehicular Adhoc Network (VANET) has went through some major technological ad vancements in the last ten years. VANET is now considered a crucial component of ITS (Intelligent Transportation System). Due to the presence of environment limitations such as mobility, reliable routing and sparse connectivity, effective message delivery and efficient use of bandwidth is a major issue in VANET. These problems cause frequent topological changes in the network which consequently affects network performance. In our proposed Destination Orientation Routing (DOR), vehicle destination is adopted as an important factor for the formation of network topology and delivery of messages. The vehicle shares its destination with the neighboring nodes. Then by using their des tination, a topology is formed between the vehicles which are in close proximity to each other. Such topology formation based on destination increases network stability and improves overall packet delivery ratio between the communicating vehicles.
