Data dissemination protocols for vehicular networks are directly dependent on the network topology to perform the dissemination in an efficient way. However, the topology of vehicular networks is constantly changing due to the dynamic behavior of their nodes. This fact contributes to increase the overhead and the data delivery delay. Therefore, the main challenge for data dissemination protocols is their adaptability to different types of network topology. Besides, there are typical problems in vehicular networks that need to be addressed: broadcast storm, partition networks, and temporal network fragmentation. Considering the challenges presented, this work proposes four protocols: ATENA, GTO, TURBO, and CARRO. The first two were developed for highway environments, the third to operate in urban environments, and the last for both environments. The proposed protocols have been extensively compared with other solutions from literature and the results showed that proposed solutions may be potencial alternatives to perform data dissemination in urban and highway environments with multiple traffic conditions. Simulation results showed that proposed protocols decrease the network overhead and guarantee message delivery to most vehicles in the region of interest (AU)
