Multi-Channel Medium Access Control for Dedicated Short Range Communications [PDF]

open access: yes, 2006
This paper describes a medium access control (MAC) protocol to enable multi-channel operation for dedicated short range communication (DSRC). In particular, we focus on the challenge of supporting potentially high-bandwidth commercial or info-tainment communications between vehicle and roadside in hotspots over several service channels, while ...
