The recent trend in Internet traffic indicates the proliferation of multimedia streaming services over wireless networks. The multimedia streaming over wireless access in unison with great mobility brings challenges to sustain the mobile user video quality high. Up to the present, several studies have been performed in order to provide prioritization of stations or services over WLAN IEEE 802.11 for improving the quality of multimedia service. The IEEE 802.11e draft specification aims to extend the original IEEE 802.11 MAC protocol to support QoS. In this paper, the authors propose a dynamic video frame mapping scheme to improve the streaming quality of SVC (Scalable Video Coding) bitstream over IEEE 802.11e.
