- Description
- High capacity IEEE802.11 networks are increasingly supporting data intensive applications. Most of streaming applications are using high quality variable rate traffic which includes HD (High Definition) and UHD (Ultra High Definition) video streaming sources. Such services demand fair QoE for all end users which requires high network QoS as well as inter and intra service fairness. It is a challenging task to offer service fairness in a random access network due to nondeterministic resource allocation techniques. In this paper, we propose two video packet scheduling algorithms for the 802.11 MAC protocol which can offer high QoS as well as fairness among video streams transmitted on the downlink using the IEEE802.11ac MAC protocol. The first algorithm is the FRATXOP that allocates transmission resources for each flow based on experienced network congestion levels to improve throughput of HD and SD video connections. The second algorithm the EAS (Enhanced Access Scheduler) operates in conjunction with the FRA-TXOP to fairly allocate transmission resources to maintain fairness among all video streams. A ns-3 simulation model was developed to evaluate the performance of the above algorithms and compare with the standard IEEE802.11ac MAC protocol. Simulation results show that proposed algorithms can enhance the high network QoS as well as maintain high QoE fairness among all end video users.
