Abstract

Several enhancements to the Medium Access Control (MAC) layer of the IEEE 802.11 standard have been recommended in the new 802.1 le standard. One main enhancement is the possibility to send bursts of frames during a limited duration called Transmission Opportunity (TXOP). Similar MAC efficiency enhancements such as Frame Aggregation have also been proposed for the upcoming 802.11n standard. We analyze the application of this feature to the existing 802.11 MAC and evaluate its performance under different network conditions. The frame bursting feature can increase the total capacity of an 802.11 network by reducing the contention and collision for bursty traffic sources. We extend the established 802.11 analytical models to include the frame bursting feature. Through simulation experiments we analyze the delay performance of the network under different frame bursting options and show that while in general frame bursting is useful and can increase the system capacity, it might cause excessive unfairness in certain cases. Using the findings of this article we present guidelines for implementing fair adaptive algorithms that use TXOP.
