Vehicle-to-Vehicle Communication System through Wi-Fi Network Using Android Smartphone

Abstract

Although IEEE has already announced 802.11p standard for wireless access in vehicular environment (WAVE) to support Intelligent Transportation System (ITS) communication, it requires additional 802.11p hardware equipment to allow vehicles communicating with others using 802.11p. Therefore, in this paper, we propose an inter-vehicle communication system, operating on android smart phone by using Wi-Fi. To substitute 802.11p onboard unit (OBU) before its widespread use on modern vehicles. Experiment results shows that our system can not only be easily installed in any android devices (android 2.3 and above) but is also more suitable for vehicular ad-hoc network (VANET) scenario than other systems.
