Abstract:

A position and traffic based routing protocol for vehicular Ad Hoc networks (VANETs) in city is proposed with using real time traffic information and mobility prediction to forward data with the idea of “carry and forward”. The protocol can work well where the destination node is moving. Simulation result shows that, compared with greedy perimeter stateless routing (GPSR), it achieves good delivery rate improvement and lower delay.

Key words: vehicular Ad Hoc, routing algorithm, position prediction
