All nodes have to tune to the Control Channel (CCH) during the CCH Interval (CCHI) for
exchanging safety messages (SMsgs) and other control messages. Nodes can optionally
switch to the Service Channels (SCHs) to exchange non-safety messages during the SCH
Interval (SCHI). The IEEE 1609.4 cannot utilize all SCHs resource during the CCHI. This
paper proposes an Efficient and Reliable MAC protocol for Vehicular Ad hoc Networks …
