Abstract

This letter highlights a key problem that arises when frame aggregation, a popular method for boosting VoIP capacity, is used in Wireless Local Area Networks (WLANs) that employ asynchronous power save mode (PSM). Specifically, it shows how the PSM proposed by the Wi-Fi Alliance renders frame aggregation ineffective. It then proposes a novel opportunistic scheduler that restores the benefits of frame aggregation whilst ensuring stations have minimal energy expenditure.
