A SIMULATION PLATFORM FOR QOS PERFORMANCE EVALUATION OF IEEE 802.11E

摘要

This paper describes a simulation platform suitable for the performance evaluation of IEEE 802.11e Quality of Service (QoS) mechanisms. 802.11e is an amendment to the IEEE 802.11 standard, describing the enhancements required for QoS provision. The aim of the platform is to provide a flexible and efficient tool for evaluating important components of 802.11e, such as traffic scheduling algorithms, admission control mechanisms and traffic classification schemes. To demonstrate the use of the platform and reveal its advantages, a case study is included, where two different traffic scheduling algorithms proposed for 802.11e are evaluated.
