Packet Routing Schemes in Vehicular Ad Hoc Networks

Abstract

Intelligent Transportation Systems (ITSs) integrate advanced computer, communication, and sensing technologies to provide efficient traffic management. Vehicular Ad Hoc Network (VANET) is an emerging technology and is a promising approach for ITS. Packet routing in VANET environments suffers from frequent disconnections due to high mobility and sparse connecting networks. In this paper, we investigate different routing schemes, and propose a series of data forwarding strategies by predicting the positions of neighboring and destination nodes. Performances of the proposed strategies are evaluated in a simulated city-map environment.
