A V2X Approach for Data Dissemination in Vehicular Ad Hoc Networks Vehicular adhoc networks are a promising type of networks that allows the communication between vehicles with the goal to promote safe and efficient traffic. During the trips, vehicles can communicate with each other and with other networks by interacting with them and with the cell phone network. In VANETs, data dissemination is a general task required by many services, which consists of the delivery of data messages to a group of vehicles. In this type of communication, the knowledge of the interactions among vehicles can help to improve the performance of data dissemination. Thus, in this work, we propose the TBD (Trajectory Based Dissemination), a solution that transmits the information on the network according to the density of vehicles in the path from the source to the region of interest. Simulation results evaluated in scenarios of various densities have shown that it is possible to reduce the number of messages transmitted with a high delivery ratio.

A Novel Protocol for Information Dissemination in Vehicular Networks The Vehicular Ad Hoc Networks (VANETs) are rapidly emerging as we are moving towards autonomous and selfdriving vehicles. Network hardware efficiency is growing day by day. However, optimal algorithms play a vital role in the effective utilization of the network. The need for supporting algorithm is vital. Cooperative network behavior is highly suitable for VANETs in comparison to infrastructurebased networks. The cooperation for active information exchange between vehicles is a prime requirement to provide safe, secure, and smoother experience on roads. Broadcasting is always the best way to disseminate information among all neighboring nodes in this kind of networks. However, broadcasting in VANET has multiple issues such as broadcast storm problem, network partition problem, network contention. The benefits of broadcasting inspire the presented research work and propose a solution as Priority Based Efficient Information Dissemination Protocol (PBEID). The work utilizes probabilitybased and densitybased information dissemination using conventional broadcasting. The work has been compared with popular techniques for information dissemination and has been statistically proven significant.
