Time Slot Utilization for Efficient Multi-Channel MAC Protocol in VANETs

Sensors, 2018
In vehicular ad hoc networks (VANETs), many schemes for a multi-channel media access control (MAC) protocol have been proposed to adapt to dynamically changing vehicle traffic conditions and deliver both safety and non-safety packets.

Stability and throughput improvement for multichannel CSMA and CSMA/CD protocols with optimal bandwidth allocation [PDF]

Proceedings Third IEEE Symposium on Computers and Communications. ISCC'98. (Cat. No.98EX166), 2002
Summary: This paper examines appropriate protocols for high-speed multiple access communication systems where the bandwidth is divided into two separate asymmetric channels. Both channels operate using slotted non-persistent CSMA or CSMA/CD techniques. The free stations access the first channel while all retransmissions occur in the second channel.
