A New Cluster Based Routing Protocol for VANET

With the development of vehicles and mobile Ad Hoc network technology, the Vehicle Ad hoc Network (VANET) has become an emerging field of study. It is a challenging problem for searching and maintaining an effective route for transporting some data information. In this paper the authors designed a new routing protocol for VANET based on the former results, called CBR (Cluster Based Routing). Compared with other routing protocols, the new one has obvious improvement in the average routing overhead and small average end to end delay jitter with the increase of vehicles number. The real-time traffic applications require data transmission delay time to be relatively stable, small average end to end delay jitter with the increase of vehicles number just meets the real-time application needs.
