Improving Relay Selection Scheme for Connecting VANET to Internet over IEEE 802.11p
Vehicular Ad hoc NETworks (VANETs) enable vehicles to communicate with each other Vehicle-To-Vehicle (V2V) as well as with roadside infrastructure Vehicle To Infrastructure (V2I) units. These units provide different services such as driver information systems and Internet access. When one node will connect to the Internet, first it must discovery the route to these units. Based only on mobility parameters, the authors can select longest life time routes to routing packet, but these routes may be with low quality of signal. So, a dropping packet and enforcing retransmission will be certainly happened.
