Executive Summary

Current literature defines the effective capacity of a wireless link as the maximum throughput that can be supported while meeting specific Quality of Service targets on packet delay. This metric can be harnessed for a wide variety of QoS control routines within wireless networks such as traffic optimization and delay sensitive admission control and routing. However to date, no empirical evaluation of the effective capacity of 802.11 wireless links has been carried out. The authors present an empirical study of the effective capacity throughput of 802.11 wireless links under a number of network scenarios. They evaluate an analytical effective capacity model and compare the result with an empirical evaluation.
