Consideration of IEEE 802.11p and proposed 5G for holograms in vehicular communication

© Institution of Engineering and Technology.All Rights Reserved. Vehicular communication is the technology that allows vehicles to exchange information with other cars and its surroundings to enhance safety and efficiency of transportation systems. Informative communication, which includes vehicle's position, velocity, and location, enables the sensing of hazards and traffic congestion. In this paper, two vehicular communication standards, Institute of Electrical and Electronics Engineers (IEEE) 802.11p and the proposed next-generation cellular network 5G are compared for vehicular networking. A detailed comparative study of the standards concerning latency, coverage, scalability, and mobility. The results indicate that IEEE 802.11p offers acceptable performance with limited mobility support. Whereas, 5G meets most of the vehicular application requirements regarding latency, coverage, scalability, and mobility. 3D holographic communication in 5G would allow users to experience live and interactive meetings. The bandwidth requirement of 3D holograms is predicted to be in terabyte level. With compression techniques, the delivery of real-time holograms has been researched to require 10Gbps or higher

Analysis of a receiver-based reliable broadcast approach for vehicular networks

The Intelligent Transportation Systems concept provides the ground to enable a wide range of applications to improve traffic safety and efficiency. Innovative communication systems must be proposed taking into account, on the one hand, unstable characteristics of vehicular communications and, on the other hand, different requirements of applications. In this paper a reliable (geo-)broadcasting scheme for vehicular ad-hoc networks is proposed and analyzed. This receiver-based technique aims at fulfilling the received message integrity yet keeping the overhead at a reasonably low level. The results are compared to simulation studies carried out in the Network Simulator-3 (NS-3) simulation environment demonstrating good agreement with each other. The analysis shows that in a single-hop scenario, receiver-based reliable broadcasting can provide good reliability, while giving very little overhead for high number of receivers
