Overview of LTE for Vehicular Communications

open access: yesWireless Personal Communications, 2020
This article provides an overview about vehicle-to-everything communications (V2X) in relation to the latest Long Term Evolution (LTE) standards. We present the main vehicular services and give a brief review of vehicular communication systems over LTE for both infrastructure to vehicle (I2V) communications over the broadcast/multicast LTE service and ...

Study on QoS support in 802.11e-based multi-hop vehicular wireless ad hoc networks [PDF]

open access: yes, 2007
Multimedia communications over vehicular ad hoc networks (VANET) will play an important role in the future intelligent transport system (ITS). QoS support for VANET therefore becomes an essential problem. In this paper, we first study the QoS performance

Security-aware dual-hop communication for amplify-and-forward relay networks

open access: yesInternational Journal of Distributed Sensor Networks, 2019
The authentication scheme for vehicular ad hoc networks aims to improve the security and integrity of message delivery. The base station manages a large number of vehicular nodes, so the security communications are non-trivial.
