ITSにおける車車間通信と路車間通信それぞれに独立に対処するには車両に二つの通信機器を搭載する必要がある.本稿では路車間通信方式であるDSRCを基に,車車間および路車間通信方式を統合するMACプロトコルDRVC(Direct and Relay protocol for Vehicle Communicatins)を提案し評価を行った.DRVCでは主に車両間の直接通信を行う.そして信頼性を向上するために車車間通信が失敗した場合,基地局を経由して間接的に通信を行う.評価の結果,DRVCではDSRCより高いスループット,低遅延が示された.ITS information communication systems are mainly classified into two types, inter-vehicle communication and road-to-vehicle communication, but to mount them, two types of communication equipment needs to be in vehicles. This paper proposes a media access control protocol for an integrated inter-vehicle and road-to-vehicle communication system based on DSRC. In the protocol called Direct and Relay protocol for Vehicle Communications (DRVC), vehicles mainly can communicate directly. To achieve the high reliability, DRVC also enables vehicles to communicate indirectly, when vehicle-to-vehicle communication is not available. As the result, DRVC shows lower delay and higher throughput than DSRC.
