Vehicular Ad hoc Network (VANET) is the emerging research area which implements wireless and mobile ad hoc Networks concepts to promote Intelligent Transport System. In VANET, Vehicles are the active nodes to collect the information and to share with other vehicular nodes for safety and commercial applications. The data dissemination is the process of distributing the relevant data to all other interested vehicles using road side units. The challenge of high mobility and frequent disconnection of vehicular nodes leads researchers to focus on data dissemination protocols. The best protocol will disseminate the data about any type of event within the bounded time, limited bandwidth and low latency. Selection of performance metrics may influence the entire research work as either easier or complex one. In this paper, we presented the important metrics that affect the performance of data dissemination by reviewing the existing data dissemination protocols.
