Performance Analysis of Broadcasting Protocol for VANET Environment

VANET has become an active area of research, standardization, and development because it has tremendous potential to improve vehicle and road safety, traffic efficiency, and convenience as well as comfort to both drivers and passengers lot of VANET research work have focused on specific areas including routing, broadcasting, Quality of Service (QOS),and security. In a network environment in which the communication medium is shared, highly unreliable, and with limited bandwidth, smart communication protocols must guarantee fast and reliable delivery of information to all vehicles in the vicinity. In VANET, several reliable broadcasting protocols have been proposed such as EAEP [3], AckPBSM DV-Cast, DECA and POCA. These protocols employ store-and forward Technique to address the intermittent-connectivity issue. This paper focus on the design of new mechanism of Broadcast protocol for Vanet environment. This mechanism achieves a high packet delivery ratio, and low control overhead. We evaluate the proposed mechanism using both theoretical analysis and computer simulation results. This paper shows how we can achieve better packet delivery ratio and average path length in Vanet and less congestion of vehicle by using a new mechanism. Keywords-Broadcasting, VANET.
