摘要：
In this paper, an analytical model is developed for the performance study of an IEEE 802.11n wireless local area network (WLAN) supporting voice and video services, considering the new features of the medium access control (MAC) protocol proposed in IEEE 802.11n, i.e., frame aggregation and bidirectional transmission. We show that these enhanced MAC mechanisms can effectively improve the network capacity by not only reducing the protocol overheads, but also smoothing the AP-bottleneck effect in an infrastructure-based WLAN. Voice and video capacity under various MAC mechanisms are compared as well.
