Abstract :
In this paper, efficient rate adaptation schemes for scalable multi-layered video transmission over wireless links with quality of service (QoS) assurance are proposed. An analytical model for QoS performance evaluation on video transmission over time-varying erroneous channels is derived. The accuracy of the analytical model is validated by simulations. Analytical and simulation results show that the proposed rate adaptation schemes can effectively improve the channel utilization and the system throughput.
