Performance Evaluation of Transmission Time Based Admission Control in IEEE 802.11
IEEE 802.11中基于传输时间的接纳控制算法研究

In this paper, a transmission time based admission control algorithm in IEEE 802.11 wireless LANs is proposed. When a new real-time flow requests to be admitted to the system, the Access Point (AP) evaluates whether the new flow will overrun the system transmission time budget. For the admitted flow, the AP adopts a token bucket to allocate the transmission time and polls the flow regularly, so the quality of service of the flow will be guaranteed. Furthermore, by means of excluding extra real-time flows, some wireless resources will be left for non-real-time services. The fairness of wireless resources sharing will be satisfied.
