When LPWAN Meets ITS: Evaluation of Low Power Wide Area Networks for V2X Communications

摘要

Recently low power wide area network (LPWAN) is widely researched and deployed due to its excellent performance of supporting large coverage, low power consumption and massive capacity. LPWAN might offer brandnew solutions to Vehicle to anything (V2X) communications, which is faced with the challenge of supporting massive connections due to the dramatically increasing number of vehicles. In this paper, after surveying the existing V2X communication technologies, we compare the traditional technologies with the representative LPWAN technologies according to their performance metrics. After the careful comparison and selection, Long-Range (LoRa) and enhanced machine type communication (eMTC) are introduced to V2X communication due to their support for mobility. Moreover, their performance are evaluated in both V2I (vehicle-to-infrastructure) and V2V (vehicle-to-vehicle) communication environments via Monte Carlo simulations.
