Vehicular WiFi access is distinct in two respects, continuous mobility of clients and possibility of predictable link quality. As part of this paper, the authors aim to comprehensively evaluate existing rate adaptation algorithms in real environments. Further, if required, they aim to develop a simple, low-overhead rate adaptation algorithm suited for vehicular WiFi access. Use of 802.11 (WiFi)-based access for communication in outdoor environments is on the rise - vehicle-to-vehicle communication, sensor network applications, delay-tolerant networks, road-side wireless access, etc. In this paper, they concern with the Vehicular WiFi Access scenario - use of roadside 802.11 installations (access points) to provide communication facilities from/to vehicles to enable networking applications.
