The authors propose a malicious detection algorithm that permits identification of misbehaving wireless stations, and then meting out punishment by not supplying an ACK packet permitting transmission by the malicious stations. The proposed algorithm is designed for IEEE 802.11e network and based upon detecting a change in QoS moving a station up in terms of a measure of permission to a level, which is not justified. The impact of non-detection will be for honest stations to set their retransmit attempts to times longer than the deadline set in order to sustain continuous receipt of their data.
