WLC24-6: An Analytical Model of Block Acknowledgement and Selective Retransmission in an 802.11e WLAN Network
Ye Chen, Steve Emeott, Romit Roy Choudhury · Globecom · 2006
The 802.11e amendment to IEEE 802.11 standard defines a block acknowledgement (ACK) mechanism to reduce the overhead required by a station to acknowledge the receipt of multiple frames. This paper presents an analytic model for estimating the overhead required to selectively retransmit data frames when using the block ACK mechanism in a noisy channel. This model is applicable both to the present block ACK mechanism and further refinements that could be proposed in a future standards amendment, such as the 802.11n high throughput task group.
