N2 - In wireless local area network (WLAN)-based vehicular networks, the performance anomaly problem is serious due to random channel access among different vehicles with diverse channel conditions and association times. To address the performance anomaly problem, we propose a signal to noise ratio (SNR)-based admission control scheme where only vehicles with better channel conditions (or higher transmission rates) are serviced by access points (APs) and thus the impact of vehicles with low transmission rates can be mitigated. The starvation issue of rejected vehicles can be resolved by considering mobility in vehicular environments with multiple intersections. Simulation results demonstrate that the SNR-based admission control scheme can improve the network throughput and the starvation problem diminishes as the number of intersections increases users.
