As IEEE 802.11 Access Points (APs) open up services to mobile clients, opportunistic access to the roadside communication infrastructures from traveling vehicles has become more prominent and has drawn considerable attention. In particular, data uploading from traveling vehicles has a great potential for many vehicular ad hoc network applications, where both the intermittent connectivity and the time-varying vehicle arrivals have presented significant challenges to the current analytical models. The authors' focus is on the carrier sense multiple access with collision avoidance-based Medium Access Control (MAC) layer performance in a last-hop drive-thru Internet, considering both the contention nature of the uplink and the realistic vehicle traffic model.
