Vehicular ad hoc Network (VANETs) have turned into an important research field in recent years. Research on VANETs aims to improve the traffic efficiency, road safety, and driver comfort. Several applications emerge to meet customer demands such as cooperative traffic information management and parking guidance. These applications need current information from several vehicles located in different geographical regions. Therefore, an important requirement for the successful, as well as the sustainable deployment in VANETs, is the scalability because the wireless communication channels have limited capacity. Moreover, many VANETs application may share the limited bandwidth resources. Therefore, it is obviously not possible to disseminate continuous current information to all network participants. In-network data aggregation has been a powerful technique for enhancing the scalability of the multihop communication, besides, reduce the bandwidth requirement. Instead of many vehicles sending every single data item of the similar content, which are all forwarded individually, data items can be merged into a useful data item. Then, through this technique can reduce communications cost while obtaining useful aggregated information. In this work, we proposed a detailed study of in-network data aggregation for VANETs. The aim of this work is the development a generic aggregation scheme that can tackle the problems found during the study. Through simulations and analysis, we expected that our approach proposed can ensure the expected performance and achieve the state-of-the-art.
