Performance Evaluation of Protocols for Inter-Vehicle Communications

Inter-Vehicle Communication (IVC) protocols have been studied to provide safe and comfortable driving. Each vehicle using the IVC protocols periodically broadcasts its current information (location, moving direction, speed, etc.), and other vehicles must receive such information exactly and in time. Other vehicles use received information to alert, advice, and navigate drivers, helping them become aware of the existence of other vehicles. This kind of application is helpful in various situations. For example, when a driver is approaching an intersection, the driver is not aware of vehicles that are also approaching the same intersection from another direction.
