The authors study the downlink scheduling performance of an IEEE 802.11-based roadside Access Point (AP) serving a number of moving vehicles. For determining the scheduling order, Throughput and Fairness are two important considerations. If System Throughput Maximization is the sole consideration, some vehicles can always get resource from the AP whereas some are starved. On the other hand, if Fairness is the sole consideration, resource should be allocated among all the contending vehicles regardless of individual vehicle's channel conditions and the system utilization should not be affected greatly.
