As new applications are created, quality of service (QoS) demand from users is getting important. The traditional IEEE 802.11 standard can not support QoS for real-time data and a new standard, IEEE 802.11e, is designed to solve the QoS issue. However, the call admission control (CAC) algorithm and the calculation of TXOP in IEEE 802.11e are only suitable for transmission CBR traffic. For VBR traffic, the loss rate will be high. The thesis first proposes CAC algorithm based on Gaussian approximation of total arrival traffic. Then a dynamic TXOP allocation algorithm is proposed to efficiently utilize the bandwidth. We will adjust the polling order according to current loss rate for every flow such that each flow has the same loss rate. Yaw-Wen Kuo 郭耀文 2008 學位論文 ; thesis 54 zh-TW
