Abstract
In this paper, cognitive wireless network for V2R and V2V communication is introduced to exchange and share road sensing and state information between the vehicle and vehicle and roadside server system. In special, two-wavelengh wireless cognitive network method is developed and implemented to improve the network performance over the conventional single wireless network. In the system, 920MHz band is used as basic connection control link to transmit user ID, SSID, key, authentication, network IP address, etc., while 2.4GHz or 5.6GHz band is used as data link to transmit road state information. By combining those wireless links, both long distance and highspeed data transmission can be attained at the same time. The prototype system of road state information system is constructed to evaluate the network performance with various network and environmental conditions.
