Vehicular Ad hoc Networks (VANETs) should provide the vehicles with reliable safety message broadcasts and efficient non-safety message transmissions. The IEEE 1609.4 MAC is designed for VANETs to support multi-channel operations, but the safety message broadcast is not much reliable and the Service Channel (SCH) resources are not fully utilized. In this(More)
The IEEE 1609.4 [1] is a MAC extension of IEEE 802.11p [2] to support multi-channel operations. However, the IEEE 1609.4 does not allow nodes to exchange non-safety messages during the CCH interval. This paper proposes a Vehicular Enhanced Multi-channel MAC protocol (VEMMAC) for Vehicular Ad hoc Networks (VANETs). The VEMMAC adopts the IEEE 1609.4 with(More)
The IEEE 1609.4 is a MAC extension of IEEE 802.11p to support multi-channel operations. 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(More)
