Finding the Sweet Spot for Frame Aggregation in 802.11 WLANs

This letter proposes an algorithm for the dynamic tuning of the maximum size of aggregated frames in 802.11 WLANs. Traffic flows with opposed requirements may coexist in these networks: traditional services as web browsing or file download that need high throughput, and services with real-time requirements that need low latency. The proposed algorithm allows the network manager to find an optimal balance (i.e. the sweet spot between throughput and latency: a delay budget can be assigned to real-time flows, with the objective of keeping the latency as close as possible to that budget, while penalizing the throughput of traditional services as little as possible.

Automated summary

The proposed algorithm aims to find the optimal balance between throughput and latency in 802.11 WLANs, accommodating both traditional services and real-time requirements.
