A New V2X Communication System to Realize Long Distance and Large Data Transmittion by N-Wavelength Wireless Cognitive Network

In V2X communication on the actual road, both the length of communication distance and the total size of data transmission must be maximized at the same time when vehicle are running on the road. The conventional single wireless communication such as Wi-Fi, IEEE802.11p, LPWA, cannot satisfy those conditions at the same time. In order to resolve such problems, N-wavelength wireless communication method is newly introduced in our research. Multiple standard wireless networks with different wavelengths are integrated to organize a cognitive wireless communication. The best link of the cognitive wireless is determined by considering their RSSI values. In order to verify the effects of our proposed method, a prototype system is constructed at the actual road and tested the performance, such as communication distance and total transmission data. Through the performance evaluation, the effects of our suggest method could be verified over the single network.
