Abstract:
In Intelligent Transportation System (ITS), communication with RoadSide Unit (RSU) is expected that weak connectivity of vehicle-to-vehicle communication can be improved since the power average of RSU is large. However, to deploy and maintain RSUs is costly. Therefore, it is necessary to effectively place RSUs within limited cost. Many opportunities to communicate with vehicles are at intersections with a lot of traffic volume. However, it is necessary to consider not only the traffic volume but also a connection relation of the road network because buildings prevent radio waves. In this paper, we propose an RSU placement method considering road elements that affect radio wave spreading. This method consists of two actions: calculation of RSU placement priority with considering road elements affecting radio wave spreading and operation of updating RSU placement priority. As a result of simulation, our proposal is particularly effective in a scenario considering information relay because the communication performance of this method was higher than or equivalent to that of other RSU placements. Further, it is found that our proposal was possible to suppress redundant RSU placement by updating operation of RSU placement priority in a scenario which is not considering information relay.
