VANETs (Vehicular Ad hoc NETworks) are receiving growing attention from the research community and from the transportation industry because of their great potential to improve traffic safety on roads. However, handling time-critical safety applications in these networks poses many challenges, particularly because such applications may have to share the communication channel with other applications. In existing system, using congestion control algorithm whether the node is active or inactive. If node is active the message is send otherwise placed in queue.
