The original motivation of Vehicular Ad hoc Networks (VANETs) was to promote traffic safety, of which the importance and potential impact have been confirmed by several initiatives supported by car manufacturers, various government agencies, and academia. Furthermore, there are considerable scope for the development of more sophisticated information rich applications, which can provide high traffic efficiency, Internet access and entertainment to the drivers and passengers. However, VANETs has its unique characteristics - spatially and temporally localized, dynamic, and data-intensive. The rich set of application requires and user interest should be taken into account. The suppression mechanism for broadcast storm problem and Delay Tolerant Network (DTN) mechanism for disconnection network are the key issues in data dissemination. Therefore, a number of challenges must be addressed in designing high performance Inter-Vehicle Communication (IVC) protocol.
