Abstract

The traditional wireless technology confronted with some short-comings in practical use, such as insufficiency for bandwidth, and lack of guaranteed on Quality of Services (QoS). Both of the packet scheduling and connection admission control are the main consideration issues toward QoS networks. These two issues are mutually correlated. In this paper, we propose a measurement based with fake priority scheme for the control of connection admission in WLAN. As the concept of the virtual source and virtual MAC (VS/VMAC) is applied, the proposed scheme will not affect the transmission of existing traffic during traffic probing. The proposed scheme also provides a difference factor (D factor) for the compensation of the performance measured by VMAC. This factor is also applied to control the tightness of the policy of connection acceptance. The simulations results show that the proposed scheme can effectively manage the connection requests while maintaining QoS in WLAN.
