A dynamic Hi-CAST protocol for safety message dissemination in VANET

Vehicular Ad-hoc network (VANET) has gaining much attention recently to improve road safety, reduce traffic congestion, and to enable efficient traffic management because of its many important applications in transportation. In this paper, we propose a dynamic safety message dissemination protocol for VANET. It can alleviate the broadcast storm problem by adaptive rebroadcast probability using fuzzy control and fading factor. The performance of the proposed approaches is evaluated through simulation. From the performance results, we can design the best protocol for safety message dissemination in VANET.
