Efficient and emergency data dissemination service in vehicular networks (VN) is very important in some situations, such as earthquakes, maritime rescue, and serious traffic accidents. Data loss frequently occurs in the data transition due to the unreliability of the wireless channel and there are no enough available UAVs providing data dissemination service for the large disaster areas. UAV with an adjustable active antenna can be used in light of the situation. However, data dissemination assisted by UAV with the adjustable active antenna needs corresponding effective data dissemination framework. A UAV-assisted data dissemination method based on network coding is proposed. First, the graph theory to model the state of the data loss of the vehicles is used; the data dissemination problem is transformed as the maximum clique problem of the graph. With the coverage of the directional antenna being limited, a parallel method to find the maximum clique based on the region division is proposed. Lastly, the method's effectiveness is demonstrated by the simulation; the results show that the solution proposed can accelerate the solving process of finding the maximum clique and reduce the number of UAV broadcasts. This manuscript designs a novel scheme for the UAV-assisted data dissemination in vehicular networks based on network coding. The graph theory is used to model the state of the data loss of the vehicles. With the coverage of the directional antenna being limited, then a parallel method is proposed to find the maximum clique of the graph based on the region division.

“…Due to the high-speed mobility of vehicles and the rapid changes in network topology, the vehicles are constantly switching between RSUs, resulting in excessive delays in downloading large files, which affects the experience of vehicle users. Therefore, the research on the data forwarding mechanism in the Internet of Vehicles has received extensive attention from many scholars at home and abroad [15]. This section introduces the data forwarding mechanism in the Internet of Vehicles in detail based on the previous research hotspots.…”

With the rapid development of the Internet of Things and the continuous progress of 5G technology, intelligent transportation has become the development trend of transportation technology. As an information interaction network, the Internet of Vehicles can share traffic information among vehicles, bringing convenience to vehicle owners while improving traffic efficiency.Data forwarding technology in the Internet of Vehicles (IoV) can realize the safe and efficient forwarding of messages, so that vehicle users can obtain road information as soon as possible and take relevant measures in advance.Cybertwin, as a complete replica of the vehicle in the virtual world, masters all the data and behavior of its physical vehicle. Cybertwin can communicate with other vehicle’s Cybertwin in the virtual world, which provides powerful functions in the data forwarding. On the one hand, it can directly forward data on behalf of the physical vehicle; on the other hand, Cybertwin can make relevant decisions based on forwarded data from other twins. However, it is easy to be eavesdropped when forwarding its physical vehicle data. In addition, there are several Cybertwins that may refuse to forward data in the virtual world. Therefore, the security issues in the data forwarding of Cybertwin face many challenges. In this paper, data aggregation and cluster-head multi-hop transmission scheme based on Cybertwin is proposed. The proposed scheme uses the reversible matrix to construct the data forwarding report of different cyber twins, uses the Paillier cryptosystem to aggregate the ciphertext of the data report, and uses the reversible matrix to decrypt and restore. In addition, use randomizable signatures to protect the privacy of Cybertwin. The security analysis results show that the proposed scheme can effectively improve the efficiency of data forwarding, and better protect the privacy and security issues of Cybertwin data forwarding in the IoV.
