An Efficient Routing Protocol for Connecting Vehicular Networks to the Internet
Résumé
Vehicular ad hoc networks (VANETs) enable vehicles to communicate with each other
(V2V) as well as with roadside infrastructure units (V2I). These units provide different
servicessuchasdriverinformationsystemsandInternetaccess.Thehighspeedandhigh
mobility of vehicles make it very challenging to establish and maintain a connection
to these units. We introduce a new protocol which uses the characteristics of vehicle
