INTEGRATION OF CELLULAR AND IEEE 802.11 NETWORKS IN VANETS

摘要

A method for transmitting messages by nodes in a vehicular ad-hoc network (VANET), wherein the nodes are equipped with first communication means for operating via a cellular network - cellular transmissions - and with second communication means for operating via wireless local area network (WLAN) channels - 802.11 transmissions - and wherein said vehicular ad-hoc network includes a central entity that serves as a message reflector to enable cellular-based communication among the nodes of said vehicular ad-hoc network, is characterized in that a node dynamically selects the network to use for transmitting messages, wherein said network selection is performed in such a way that a predefined performance metric is optimized.
