Development of prototype product of Vehicle Ad-hoc Network communication terminal

Vehicle Ad-hoc Network (VANET) communication terminals, e.g., On Board Unit (OBU) and Road Side Unit (RSU), are crucial devices to facilitate the implementation of VANET systems. Based on the Wireless Access in the Vehicular Environment (WAVE) protocol stack and embedded development technology, we in this paper propose a complete designing approach to realize the VANET communication terminals in both hardware and software layer. The key feature of our proposed approach is that we adopt 802.11p module as the Radio Frequency (RF) front end, U-Blox8 as the Global Navigation Satellite System (GNSS) module and i.MX6 Dual Lite as the processing core. The designed VANET terminals can provide effective communications for both vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) connections, and thus enable the timely delivery of varied transport information.
