This paper describes a vehicle-to-vehicle communication protocol for cooperative collision warning. Emerging wireless
technologies for vehicle-to-vehicle (V2V) and vehicle -to- roadside (V2R) communications such as DSRC are promising to reduce
the number of fatal roadwayaccidents by providing early warnings. Based on a careful analysis of application requirements, we
design an effective protocol, comprising congestion control policies, service differentiation mechanisms and methods for
emergency warning dissemination.. Dedicated Short Range Communication (DSRC) radio technology, being standardized as
IEEE 802.11p, is projected to support low-latency wireless data communications between vehicles and from vehicles to roadside
units. DSRC has overcome many collision drawbacks that were present in IEEE 802.11b, the first version of DSRC by
transmitting at the rate of 6-27 Mbps and at a range of 1Km. The previous version transmitted at a rate of 0.5Mbps and for a
range of 100 Mts.
