Abstract
To differentiate services for various traffic categories (TCs) in 802.11eD.2.0 [1], TCs possess different minimum contention window (CWmin) values, which are static over duration. Performances of low priority traffics (FTP) with higher CWmin values are suppressed even during absence of high priority traffics (video and voice). In this paper, we propose a modified backoff scheme called Dynamic Offset Contention Window (DOCW) algorithm, which dynamically adjusts CW values of traffics to network conditions. It is shown by simulations that the proposed algorithm enhances throughputs of low priority traffics where QoS is provided as well.
