Optimal transmission range for V2I communications on congested highways
2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)(2017)
摘要
In this paper, we analyze the performance of vehicle-to-infrastructure (V2I) communications on a highway, in which the transmission distance between a road side unit (RSU) and a vehicle rapidly changes due to movement of vehicles. By theoretically analyzing the interference received at an RSU, we derive a closedform expression of a desired performance metric of V2I communications. Furthermore, by considering the trade-off between the interference at an RSU and the transmission range of a running vehicle, we obtain a closed-form optimal transmission-range for V2I communications. We evaluate our analysis results by conducting numerical simulations and show the effectiveness of the optimal transmissionrange.
