[Abstract]:In view of the problem that the current defense DoS attack method has insufficient defense performance due to too many conditional attributes of the legitimacy of the attack frame, based on the rough decision theory and the rough decision rule method, the model of defending the wireless DoS attack is established, which is based on the rough decision theory and the rough decision rule method. An intelligent frame filtering algorithm for defense DoS (802.11w-SFF) based on rough decision rules is presented and analyzed experimentally. When the attack rate of 802.11w-WiFi device is 250fps, the 802.11wSFF method is not used. The loss rate of TCP is increased to 80 when there is no attack. After using the 802.11w-SFF method, the TCP/UDP data communication performance of the 802.11wWiFi device is not affected by the DoS attack. The experimental results show that the 802.11w-SFF method can effectively defend against DoS attacks in mobile networks.
