Their properties are suitable for the ADAS (Advanced Driving Assistance System) applications on smartphones. In this paradigm, a smartphone need to connect with the sensitive information of a vehicle. The quality of this data exchange is an important issue. To do this, we design and implement a VLC system that uses two components: a modified reading light and an USB optical transceiver. In our paradigm, these two components are fixed inside a vehicle. This constrained mobility is suitable for our VLC system. Comparing RF communication, our VLC system provides a stable short range communication with limited transmission power and LOS property. This is an ideal candidate to achieve a stable, secure and private data transmission for ADAS applications. In this work, a VLC for prototype based on commercial LED is presented and tested. This experimental study has proved that our VLC prototype is realistic for providing a good enough quality of the data link and can run on resource-constrained platforms.","PeriodicalId":150652,"journal":{"name":"2018 Global LIFI Congress (GLC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116725434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
