In Wireless Local Area Networks (WLANs), Quality of Service (QoS) can be provided by mapping applications with different requirements (e.g., delay and throughput) into one of the available Access Categories (ACs), as is done in the IEEE 802.11e standard. With the increasing programmability of network adapters, a malicious user can strategically declare a higher AC for its application to gain an unfair share of resources. This can drastically degrade the network performance and avoid adequate service distinction among different ACs. In this paper, the authors use the technique of mechanism design in game theory to tackle this problem in WLANs with random access.
