| Abstract(in English) | The demand for Internet access in vehicles has been growing. One of necessary communication systems in the Internet access is a road-vehicle communication system, where user terminals in the vehicles directly connect to the wireless access points (AP). However, mobility speed of vehicles is so high that the channel condition between the terminals and the APs dynamically changes due to path loss changing and fading by the Doppler shift. One solution for this problem is packet relaying. If a terminal sends data via other vehicles driving with lower speed, the relative mobility speed will decrease, which reduces dynamic range of path loss and deterioration by fading. We evaluate this method through a numerical analysis to verify the availability of the method. In addition to packet relaying, the difference of hardware limitation between user terminals and vehicles is also discussed. |
