Ruiz-Mas, J. Almodovar, C.J.L. Publication year 2017 Abstract Frame aggregation is widely used in 802.11 WLANs in order to provide a significant throughput improvement. However, the latency increase that comes as a counterpart can reduce the quality experienced by the users of applications with real-time constraints. This letter explores the throughput versus latency tradeoff in the context of central controlled solutions (e.g. SDWN-based). First, a scenario with a single Access Point (AP) is used to illustrate the problem and to propose two possible solutions. Then, a centralized algorithm that dynamically (de)activates aggregation is tested in a scenario with a number of APs. The results show that aggregation arameters can be tuned in order to keep latency in low levels, with a low throughput penalty Subject 802.11frame aggregationreal-time serviceswireless LANEconomic and social effectsWireless local area networks (WLAN)802.11Access pointsCentralized algorithmsFrame aggregationLatency increaseReal time constraintsReal time serviceThroughput improvementAgglomeration To reference this document use: http://resolver.tudelft.nl/uuid:98297ef9-9494-421a-9023-9c7581d1b890 TNO identifier 954821 Publisher Institute of Electrical and Electronics Engineers Inc.
