We propose a dissemination system using multiple roadside units (RSUs) on a two-way roadway. To enhance the performance of data services, data items are disseminated through a hybrid of infrastructure-to-vehicle (I2V) and vehicle-to-vehicle (V2V) communications. Unserved requests in RSU’s coverage are transferred to the next RSU located in a vehicle’s trajectory. In this way, channels are utili...

This paper presents a formal verification of a safety message dissemination protocol used in vehicular adhoc networks. It is proposed to use Road Side Units to broadcast road hazard information to vehicles travelling on highways. Quick dissemination of road hazard information, like road blocks, slippery roads and other obstacles can help to prevent road accidents and improve passenger safety. F...

The concept of the “connected car” offers potential for safer, more enjoyable and efficient driving eventually autonomous driving. However, in urban Vehicular Networks (VNs), high mobility vehicles along roads poses major challenges to routing protocols needed a reliable flexible vehicular communications system. Thus, VNs rely on static Road-Side-Units (RSUs) forward data extend coverage across...

Abstract The generation of the pseudonym in vehicular ad hoc networks (VANETs) usually requires participation a trusted center (TA), and it needs multiple interactions with TA. To address these problems, we propose novel traceable self-generated based on non-interactive zero-knowledge proof (NIZK) consortium blockchain VANETs. In our scheme, pseudonyms method is introduced to eliminate excessiv...

In the past decades, traffic problems has become a major research field of both academic and industrial community. In this paper, we propose a SelfAdaptive Navigation System (SeNS) to provide optimal tailored driving paths, reflecting real-time road traffic information. The current navigation systems are using server independently, and only use the static time stamp-based traffic information. F...

In the future vehicular networks with an increased number of transceiver antennas and higher vehicle speeds, more frequent beam switching is required to ensure quality communication, which poses challenges tracking speed resource efficiency. Integrated sensing communication (ISAC) provide a new solution cope this problem since radar echo can help predict vehicle’s location direction. Therefore,...

In VANET (Vehicular Ad Hoc Network), vehicles moving from one RSU’s coverage region to another will cause access congestion problem if vehicles use improper handover scheme. In this paper, we present a novel mobility handover scheme for vehicles with seamless Internet access in urban VANET scenario, which is called Game approach for Handover Scheme based on Road-section (GHSR). The main advanta...

In this paper, we introduce the theoretical foundations of FRIEND: A cyber-physical system for traffic FlowRelated Information aggrEgatioN and Dissemination. By integrating resources and capabilities at the nexus between the cyber and physical worlds, FRIEND will contribute to aggregating traffic flow data collected by the huge fleet of vehicles on our roads into a comprehensive, near real-time...

Information sharing in vehicular networks has great potential for the future Internet of Vehicles (IoV). and roadside units (RSUs) can exchange perceptual information driving experience to enable intelligent transportation applications such as autonomous road condition analysis. However, ensuring secure efficient among vehicles is challenging. While traditional blockchain guarantee tamper-proof...

Vehicular Ad-hoc Networks (VANETs) place an important role in the development of better transportation systems. Road Side Unit (RSU) is the one of the main component of VANETs. In this paper, we propose a mechanism for registration of the arrival of new vehicle into the networks. RSU acts as a local registration unit for the network registration of any vehicle. In VANETs most of the interaction...
