Abstract

Unlike most of the existing studies on video streaming over WLANs, which usually focus on only one type of video streams, either stored videos or live videos, in this paper we propose a dynamic scheduling method for transmitting a mixture of live and stored videos over WLANs. In particular, we dynamically estimate the future IPTV traffic information based on the past. Our proposed dynamic scheduling algorithm allows VoD traffic to be transmitted not only at a later time but also in advance so as to provide more flexibility to serve the overall traffic to achieve a better QoS. The ns-2 simulations verify the effectiveness of the proposed approach.
