Design of 5.9 ghz dsrc-based vehicular safety communication

Daniel Jiang; Vikas Taliwal; Andreas Meier; Wieland Holfelder; Ralf Guido Herrtwich

The automotive industry is moving aggressively in the direction of advanced active safety. Dedicated short-range communication (DSRC) is a key enabling technology for the next generation of communication-based safety applications. One aspect of vehicular safety communication is the routine broadcast of messages among all equipped vehicles. Therefore, channel congestion control and broadcast performance improvement are of particular concern and need to be addressed in the overall protocol design. Furthermore, the explicit multichannel nature of DSRC necessitates a concurrent multichannel operational scheme for safety and non-safety applications. This article provides an overview of DSRC based vehicular safety communications and proposes a coherent set of protocols to address these requirements

Das vernetzte Automobil

Ralf Guido Herrtwich; Wieland Holfelder

In vielen Bereichen des taglichen Lebens spielt das Internet und die damit verbundene Moglichkeit, auf Informationen standig und von uberall aus zugreifen zu konnen, eine immer bedeutendere Rolle. Bislang gehorte das Automobil nicht dazu — bislang. Scott McNealy, Chairman und CEO von Sun Microsystems, sieht das Automobil als „das nachste Schlachtfeld der Informationsrevolution“ [1]. In der Tat, Automobilfirmen sowie IT-Giganten wie Sun, IBM und Microsoft arbeiten mit groser Energie an Losungen, die Moglichkeiten einer vernetzten Welt, der e-Society, auch im Automobil gewinnbringend und zum Nutzen der Kunden umzusetzen.
