“…In order to overcome the intermittent data delivery service of RSUs that derives from the limited communication coverage of RSUs, Cho and Ahn 14 proposed the backup route mechanism in preparation of route disconnection from the serving RSU, as well as the handover mechanism between two neighboring RSUs, aiming to enhance the data delivery performance in the vehicular communication environment where RSUs are sparsely placed. Chen et al 15 proposed a method for adjusting the data transmission rate according to the number of periphery APs to solve the problem of continuity and reliability, which is caused by frequent handoff with base station due to high mobility of vehicles. Chen et al 16 proposed a cooperative communication strategy for vehicular networks with a finite vehicular density by utilizing V2R communications, V2V communications, mobility of vehicles, and cooperations among vehicles and infrastructure to improve the throughput.…”

Safety-related and user-related applications are two main kinds of services provided in vehicular ad hoc networks. Safety-related applications have great impact on vehicles and people who participate in the transportation. The quality requirements for safety data dissemination are strictly high, since this kind of service is usually concerned with the most important safety events in vehicular ad hoc networks. Meanwhile, user-related applications need to fulfill the varied demands for value-added services of consumers in vehicular ad hoc networks to retain existing consumers and to attract new ones. However, the unpleasant transmission environment of vehicular ad hoc networks, such as drastically changing network topology and unstable communication links, degrades the system performance and hinders the development of vehicular ad hoc networks. To tackle these issues, this article proposes a novel algorithm which prioritizes data based on their service purposes and schedules the most rewarding data item based on utility values calculated with multiple parameters, including data requirements of vehicles, vehicles density, speeds, and locations. Moreover, the algorithm applies instantly decodable network coding technique on the scheduled data to maximize the multicast throughput. Simulation results approve the performance advancement of the proposed algorithm in download delay, deadline miss ratio, and download success ratio for high-and low-priority data disseminations.
