“…They can obtain the location information at any time with equipped global positioning system (GPS) devices. We assume that vehicles travel nearly at a constant velocity, and the routes of vehicles can be predicted (similar to the assumptions made in the works by Chen and Chan, 13 Trullols-Cruces et al, 14 and Liu et al…”

“…other vehicular users) and reduce the effect on intermittent connectivity in dark areas. 13,14 It means when a vehicular client drives in a dark area without finishing the whole downloading, these unfinished contents are then delegated to cooperative vehicles and further transmitted to clients by a carryand-forward mechanism 15 in dark areas. However, those works ignore the cooperative intention of vehicles and the optimization of the whole cooperative downloading process.…”

“…They can download contents from the Internet via the edge of the cloud, RoadSide Units (RSUs). A good user experience can be achieved within the coverage of RSUs which is about 300-1300 m. 12 However, in highway scenarios, RSUs are mainly deployed at service areas or gas stations which are [8][9][10][11][12][13][14][15][16] km apart. It is impossible to expect a high number of well-deployed RSUs due to cost restrictions and high maintenance overhead.…”

In vehicular cyber-physical systems, vehicular users are the edge nodes which are far away from the network core. Content accessing and downloading for vehicular users are expected to heavily rely on the deployment of RoadSide Units in vehicular cyber-physical systems. Although vehicular users can obtain a good content downloading service in the coverage of RoadSide Units, user experience will get worse in highway scenarios, where RoadSide Units are sparsely deployed at service areas or gas stations. In other words, the download process has a property of intermittent connectivity because many no-signal areas (dark areas) exist on the road. In this article, we try to address such shortcomings by exploiting other edge nodes (vehicles) to download contents for clients in dark areas. Considering the cooperation intention of vehicles, we first propose an incentive mechanism to stimulate vehicles to participate in cooperative downloading. Next, with an objective of maximizing the utilization of benefits, we formulate the cooperative vehicle selection problem as an optimal multiple stopping problem and derive the optimal multiple stopping rule for cooperative downloading. Finally, an extensive simulation study has been performed to investigate the effectiveness of our scheme. The results reveal the impact of different parameters on system requirements and demonstrate that the proposed scheme can maximize the throughput of content downloading in dark areas.

“…Due to the high cost associated with roadside units or access points, these schemes are not very feasible in practice. Trullols-Cruces et al [25] propose a vehicular framework that opportunistically allows downloading packets when vehicles cross AP, works as a delay-tolerant network and benefits two cooperative mechanisms: (i) a DC-ARQ to recover packet losses due to the harsh physical conditions and (ii) a carry and forward mechanism to improve throughput and total transfer delay.…”

Fuzzy logic-based integrity-oriented file transfer for highway vehicular communications

Effective file transfer is fundamental to many applications in highway Vehicular Ad Hoc Networks (VANETs), e.g., social network applications, advertisement distributions, road traffic report, etc. However, due to the sparse development of roadside units (or access points) and the limited connection time between fast-moving vehicles, file transfer is susceptible to frequent interruptions, and accordingly resulting in incomplete file transfers. The incomplete file transfer leads to not only poor user performance with application playback failures, but also a colossal waste of bandwidth. To tackle this issue, in this paper, we consider a bi-directional highway vehicular network scenario where request vehicle and source vehicle are in the opposite direction, and propose a fuzzy logic-based cooperative file transfer scheme (FL-CFT). With the proposed scheme, the request file can be transferred completely from the source vehicle to request vehicle through multiple relay cluster members. As for the selection of relays, in general, finding an optimal relay subject to multiple constrains is an NP-complete problem that cannot be exactly solved in polynomial time. Accordingly, a fuzzy logic approach is utilized to optimally selects relays to help transfer the file and ensure the file integrity, which considers the relative velocity, distance, and predicted connection time among vehicles. The proposed scheme is self-organized and fully distributed, which does not require any assistance from roadside units (or access points). Simulation results show that FL-CFT outperforms the state-of-the-art file transfer schemes in file integrity on highway VANETs.
