A Survey on Controlling the Congestion in Vehicleto-Vehicle Communication

The evolution of VANETs (Vehicular Ad-Hoc Networks) is assumed to be an essential move for obtaining security as well as productivity in ITS (Intelligent Transportation Systems). One most significant provision of security applications is that vehicles can interact with adjacent vehicles, through extremely low latency as well as packet loss. The great movement, unstable quality of channel as well as high information rates make all this as a challenging query in the field of VANETs. There occurred an important investigation exercise in recent times for the evolution of congestion control algorithms that guarantees safe and secure transmission of security data in vehicle-to-vehicle communication. In this article, we offer a complete review of strategies used for controlling the congestion in the domain of VANETs. We recognize the important metrics as well as special parameters which is used to estimate these strategies moreover examine every method based on various factors for example metrics applied, type of messages, rate/power control and simulators used. We end this article with amazing supplementary ideas for creating a vehicle to vehicle communication protocols as well as exciting and accessible research difficulties to be handled in the future.
