Opportunistic Wireless Internet Access in Vehicular Environments Using Enhanced WAVE Devices

다국어 초록 (Multilingual Abstract)

The emerging Car-to-Car communication (C2C) technology, known as Wireless Access in Vehicular Environments (WAVE), enables vehicles on the roadway to communicate with each other and with the roadside infrastructure. In addition to safety-relevant services, drivers may also need Internet access through C2C communications for infotainment services and car maintenance services, as specified in MobilitY and CollAboRative Work in European Vehicle Emergency NeTworks (MYCAREVENT) project. In this article we propose solutions for providing on-board Internet access service to automotive users through C2C communications. The proposed solutions make use of roadside infrastructure and the novel MYCAREVENT Vehicular Communication Gateway (VCG) device. A management scheme is developed for the opportunistic wireless links between On-Board Units (OBUs) and Road-Side Units (RSUs), as well as between OBUs and VCGs in vehicular communications. Furthermore, we invent a novel MAC queue architecture addressing the drawback of the current WAVE MAC protocol in supporting unicast traffic in highly dynamic vehicular environments. At the end, stochastic simulation results are presented to prove the concepts and validate the proposed solutions.
