Abstract :
The increasing demand for mobile video delivery has boosted the development of mechanisms which improve the Quality of Service (QoS) of video transmission through bitstream adaptation. In this paper, we study adapting H.264/SVC streams in the MAC layer. We introduce a generic QoS architecture for implementing both inter- and intra-traffic class QoS for scalable video streams, and verify the solution with OPNET simulations in the context of IEEE 802.11e EDCA. The results show that our two-tier hierarchical scheduling approach provides for optimized SVC delivery in. 11e networks without hampering the channel access of the other traffic types.
