Abstract

Due to the harsh Quality of Service (QoS) requirements of video streaming, it is a great challenge to provide multimedia service over wireless networks. In this paper, we consider video transmission in IEEE 802.11e networks, and propose a Load Adaptive Dynamic Mapping (LADM) scheme to improve the video transmission quality. In LADM, the enqueue rate of different kinds of packets and the dequeue rate of the queues are used as detailed indication of traffic load. Then the video packets are dynamically mapped into appropriate access categories according to both the significance of the video data and the network traffic load. To further improve the video transmission performance, the active packet discarding method is adopted to protect more important packets in case of heavy traffic load. The simulation results show that the LADM scheme improves the Peak Signal to Noise Ratio (PSNR) of the received video.
