Vehicular ad-hoc network (VANET) is a potential player in an intelligent transportation system that would increase road safety as well as road confort. In VANETs, vehicles excahnge road-related information either through an established infrastructure, which is costly, or through their collaboration when in common transmission range which the authors adopt in this paper. Information dissemination is realized through broadcasting, thus an intelligent selection technique should be deployed to decrease the traffic load caused by unnecessary rebroadcasting. In this paper, they propose an interest-aware data dissemination protocol that periodically exploits the current neighbors interests to select the proper set of data to be broadcasted. The proposed approach is structure-less and imposes minimum overhead on the communication bandwidth. The protocol is evaluated through simulation experiments and results obtained demonstrate that this approach maximizes the number of relevant data reports received by the vehicles, especially if a certain data type is more popular than the others. The paper is organized as follows. Section 2 presents the different dissemination approaches suggested before. Section 3 presents an overview of the proposed interests-sensitive dissemination algorithm. In section 4, the simulation experiments and the analysis of the obtained results are discussed. Finally, section 5 concludes the paper with proposals for future work.
