Abstract

IEEE 802.16 (WiMAX) uplink behavior is a relatively neglected area of investigation, but emerging interactive multimedia services have highlighted the need for closer investigation of uplink issues. In this simulation study of uplink queue management, video streaming by TFRC was found to offer advantages. However, temporal behavior of the queuing disciplines exhibits oscillations in buffer occupancy with build-up of delay during video streaming. The study offers a strategy to cope in these circumstances based on video frame type inspection.
