In this paper two simple but efficient Call Admission Control (CAC) strategies for IEEE802.11 WLANs are investigated, which are both based on a simple centralized evaluation of the current network congestion level. A realistic scenario has been considered for the evaluation of the proper choice of the CAC parameters as well as for the assessment of the performance level they provide for different traffic mixes. Simulation results show that the investigated CAC strategies could significantly improve users satisfaction and network fairness.

Abstract
In this paper two simple but efficient Call Admission Control (CAC) strategies for IEEE802.11 WLANs are investigated, which are both based on a simple centralized evaluation of the current network congestion level. A realistic scenario has been considered for the evaluation of the proper choice of the CAC parameters as well as for the assessment of the performance level they provide for different traffic mixes. Simulation results show that the investigated CAC strategies could significantly improve users satisfaction and network fairness.File in questo prodotto:
