Connecting vehicles among themselves and with the roadside infrastructure has the potential to significantly enhance safety, reduce traffic
congestion, and help preserve the environment. As roadway environments impose a series of interesting challenges of an unprecedented nature, traditional wireless systems cannot be directly adopted for vehicles communications.
This tutorial presents the main fundamental principles that form a basis for effective vehicle communications protocols design. It focuses on Dedicated Short Range Communications (DSRC), the 75 MHz spectrum band around 5.9 GHz allocated in the U.S. specifically for this purpose and describes the most recent ideas under discussion as DSRC protocols are reaching their maturity. How should protocols be designed? What support is needed for vehicular applications? How can we achieve the high reliability and low latency that are necessary for vehicle safety? This tutorial illustrates at a high level the most challenging aspects of DSRC including scalability, channel switching, and security. As the communications system is analyzed and discussed, constant attention is dedicated to the automotive side so that the examples and cases that are presented reflect realistic application scenarios. Furthermore, ideas are provided on how DSRC applications can be built and fully integrated in vehicles.
Bio: Luca Delgrossi holds a PhD in Computer Science received from the Technical University of Berlin, Germany. Among his past activities, he worked on real-time multimedia communications in their early stage at the International Computer Science Institute (ICSI) at UC Berkeley, CA, and the IBM European Networking Center (ENC) in Heidelberg, Germany. He served as Co-Chair for the Internet Engineering Task Force ST Working Group producing Internet RFC 1819 (IP version 5), and as Associate Director for the Centre for Research on the Applications of Telematics to Organizations and Society (CRATOS) of the Catholic University of Milan (Italy). He is among the founders of the Italian Chapter of the Internet Society.
Today, Dr. Delgrossi leads the Vehicle-Centric Communications (VCC) team at Mercedes-Benz Research & Development North America, Inc. in Palo Alto, CA. The VCC team implemented the first on-board equipment (OBE) with a 5.9 GHz Dedicated Short Range Communications (DSRC) radio performing channel switching (2006) and publicly demonstrated a Mercedes-Benz S-550 coming to stop automatically upon detection of an imminent red light violation at an instrumented intersection (ITS World Congress New York, 2008). He serves as Chairman of the Board of Directors at the Vehicle Infrastructure Integration Consortium and as co-editor of the IEEE Communication Magazine Automotive Series.
