Abstract(in English) | Standarization activities and development for practical application of inter-vehicle communication systems are actively undertaken in Europe, United States, Japan, and so on. Access schemes in those systems are mostly based on CSMA/CA, which is popularly used in Wireless LAN. However, it is also well known that performance of CSMA/CA significantly degrades when the number of terminals is large and their density is high. This paper presents a novel access scheme that is based on distributed CDMA combined with multi-hop packet forwarding. This scheme effectively uses the well-known near-far effect of CDMA to avoid hidden terminal problems and provides the packet success ratio as high as 100% with small transmission latency. An Overview of recent study on pedestrian-to-vehicle communication is also presented. |
