Abstract: Vehicular Ad Hoc Network applications plays an important role in improving the quality and efficiency of transportation system .To improve transportation safety vehicles exchange safety messages among them which helps to reduce accidents and chain collision. In the existing system flooding technique is used for broadcasting safety messages which leads to congestion when the traffic density increases and consequently packet loss occurs In this paper we propose an analytical model that helps to exchange Safety message with high performance by using intelligent routing protocol and congestion control mechanisms .By reducing the congestion ,reliability increases and delay decreases, consequently the performance of emergency message diffusion increases. The paper also proposes solutions to reduce the effect of hidden terminal problem in successful reception of packet in VANET .The model also proposes the ways to enable connectivity in dense, sparse and isolated traffic condition.
