Ad-hoc IEEE 802.11 LANs employ CSMA/CA at the MAC layer. CSMA/CA selects a random backoff time from a contention window that grows from w/sub min/ to w/sub max/ upon consecutive frame collisions. A selfish backoff attack by configuring small w/sub min/ and/or w/sub max/ (i.e., systematic selection of short backoff times) brings the attacking station an unfairly large long-term bandwidth share. To evaluate the impact of backoff attacks we use Bianchi's model of a saturated CSMA/CA network. So… CONTINUE READING
