Content dissemination, in particular small-volume popular content dissemination, represents a killer application of vehicular networks, which is also fundamental to the delivery of advanced infotainment applications, such as vehicular social networks, road traffic alerts, etc. The content dissemination in vehicular networks relies on moving vehicles to relay and propagate contents. Due to challenges...
Broadcasting of real-time video, especially accidents relevant, plays an important role in Vehicle Ad-hoc Networks (VANETs). Multi-view video enables the perception of the targeted scene from multiple angles. By subscribing the real-time multi-view video broadcast, drivers can obtain better knowledge of the highway traffic and road conditions. However, compared with the traditional single view video...
This paper aims to present a methodology and a set of tools that could be used in order to check the validity of an Intelligent Transport System. These tools will consider each ITS component, i.e. C-ITS- R (Road Side Units) RSU, C-ITS-V (On-Board Unit) OBUU, C-ITS-C (Central Server) with its specific fea- tures as location precision for an OBU and adequate forwarding of dangerous events for an RSU...
The very high mobility of the nodes in Vehicular Adhoc Networks (VANET) increases the rate at which the handoff occurs. This motivates researchers to investigate the novel strategies for channel allocation such that the handoff becomes transparent. At the same time the utilization of the channels need to be effective in order to enhance the QoS. Hence this paper proposes a channel reservation procedure...
Vehicular cloud, which is constituted by gathering the under-utilized on-board capabilities on the road, has received considerable attention in recent years. In this paper, we propose a novel secure and privacy-preserving incentive mechanism in vehicular cloud, which employs the Stackelberg Game to model the interaction between the leader and follower vehicles. With the proposed incentive mechanism,...
The study item: "Feasibility Study on LTE-based V2X Services", approved at 3GPP TSG RAN #68, has aroused the interest in the study of LTE assisted vehicle-to-vehicle (V2V) and vehicle-to- infrastructure (V2I) communications in the networks of connected vehicles. By deploying the direct device-to-device (D2D) technology of traditional cellular networks into the V2X (including both V2V and...
Route guidance and navigation services have been widely attracting researchers and application developers due to the serious problems of traffic congestion and the ceaseless need to improve the driving experience. Motivated by such driving concerns, this paper proposes a real-time, dynamic route guidance system with the main focus on the driver safety and satisfaction. As a unique feature compared...
Future hybrid vehicle networks can use both Vehicle-to- Infrastructure (V2I) and Vehicle-to-Vehicle (V2V) communications to provide reliable, timely, scalable, and media-rich services. In this paper, we investigate the problem that how to disseminate the data to the Road Side Unit (RSU) considering bidirectional transmissions, using vehicles to store-carry-and-forward the messages if possible, in...
With more and more trajectory traces available, conducting analysis and mining on those trajectories can obtain valuable information. Although the published traces are often made anonymous by substituting the true identities of mobile nodes with random identifiers, the privacy concern remains. In this paper, we propose a new de-anonymization attack based on the movement pattern of moving objects....
Since GPS signal is not applicable indoors, vehicle tracking has proven a hassle in underground parking structures. Recent solutions highly rely on floor map to constraint inertial sensors noises. In this paper, we propose VeMap, a road map construction system using only smartphones inside vehicles. It saves effort-intensive and time-consuming business negotiations with building operators, and expensive...
Vehicular Ad-hoc Networks (VANETs) technology has been utilized in recent applications to enhance the traffic fluency over the road network. Various types of emergency cases may negatively affect the efficiency of traffic flow in highway road scenarios, including accidents, damaged vehicles or the presence of emergency vehicles. These cases exaggerate...
This paper studies the charging problem of plug-in hybrid electric vehicles (PHEVs) with a game theoretic approach. The interplay between PHEVs and smart micro-grid charging stations are modeled as a multi-leader-multi-flower Stackelberg game. In the game, each PHEV needs to select a charging station for maximum utility given the charging prices from each station; and each charging station needs to...
Content distribution in vehicular networks is greatly impaired by high mobility and intermittent connectivity. Social-aware content distribution schemes based on typical centrality metrics address the challenge, however they suffer due to their network-centric nature instead of information centric. We suggest to exploit the recently proposed information-centric networking architecture which cater...
Acquiring accurate location information of vehicles is of great importance. Global Positioning System (GPS) has been widely deployed and used to be the most convenient solution to outdoor localization. As more and more infrastructure such as elevated roads, tunnels and tall buildings is built, however, the ever-increasing complexity of urban environments makes vehicle localization especially in those...
