Improving V2I Edge Communication by Performance Maps

2015 8th IFIP Wireless and Mobile Networking Conference (WMNC), 2015
Vehicle-to-infrastructure (V2I) communication is important for the collection of probe vehicle data and traffic information. When using IEEE 802.11 as access technology (ITS-G5 or WAVE), the communication between moving vehicles and fixed infrastructure, such as roadside stations, is most efficient when the passing vehicle reaches a window of ...

V2V & V2I for connected vehicle

2018 International Symposium on VLSI Design, Automation and Test (VLSI-DAT), 2018
Considering the installed automotive sensors like camera, radar and LiDAR which provide the cognition of vehicle surrounding environments, the most concerning point is its high cost compared to the other convenient parts in the car today. There is another way to provide similar features these sensors can do but with cheaper price.

Optimal configuration of roadside beacons in V2I communications

Computer Networks, 2011
Dedicated Short Range Communication (DSRC) standards have been defined as the physical and MAC layers in the context of vehicular communications. In this work the performance of DSRC communications are analyzed in the context of roadside to vehicle environments for different traffic loads.

Adaptive data rate transmission for V2I communication

2016 International Conference on Information and Communication Technology Convergence (ICTC), 2016
In vehicle-to-infrastructure (V2I) communications, continuity and reliability are the most severe issues. Owing to the high-speed mobility of vehicles and frequent hand-off, the connection between vehicle and access point (AP) could not be kept stable.

Predictive analytics for non-stationary V2I channel

2017 9th International Conference on Communication Systems and Networks (COMSNETS), 2017
Vehicle to Infrastructure (V2I) channels are particularly difficult to analyze because of high mobility and localized scattering from nearby vehicles and road-side features. The spatio-temporal variation of the scattering environment makes the channel a non-stationary stochastic process, which renders conventional, receiver-side channel conditioning ...

Reinforcement Learning in V2I Communication Assisted Autonomous Driving

ICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020
A novel framework is proposed for enhancing the driving safety and fuel economy of autonomous vehicles (AVs) with the aid of vehicle-to-infrastructure (V2I) communication networks. To solve this pertinent problem, a double deep Q-network (DDQN) algorithm is proposed for making collision-free decisions.

Low-Latency Secure Roaming in V2I Networks

2018 VIII Brazilian Symposium on Computing Systems Engineering (SBESC), 2018
Secure communication is a key requirement for vehicular networks. However, high mobility and density bring several challenges to the roaming mechanism needed to handover the control of vehicles as they move along the roads. Authentication and key management must take place on the way, with strict timing and safety requirements that are seldom matched ...

Trajectory prediction to avoid channel congestion in V2I communications

2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2017
In the new envisaged paradigm of vehicular communications, critical safety applications have strict requirements in terms of latency and robustness due to the critical nature of their mission that require periodic status exchange and asynchronous event notifications for a reliable cooperative awareness. Current technologies like IEEE 802.11p and recent

Performance modelling and evaluation of V2I video surveillance system

2015 Twelfth International Conference on Wireless and Optical Communications Networks (WOCN), 2015
Multi-hop transmission of real time video in IEEE 802.11p from vehicle to infrastructure access point and then via other access points to the server is addressed in this paper. We perform the feasibility study of such systems by analyzing the end to end quality of distortion in video signals among many competing vehicles, to and from the tagged vehicle
