A location-based method for restricting the flooding DoS effect in WLANs
Rajeev Singh, Teek Parval Sharma · Journal of Location Based Services · 2015
WLANs are prone to flooding denial-of-service (DoS) attacks. Present research work proposes a novel method to enhance WLAN security by restricting flooding DoS effect on the access point (AP). Each node in the proposed method listens transmission of other neighbouring nodes and sends at regular interval a linked list to AP, containing the identifiers (IDs) of all nodes from which it hears. AP stores the linked list information and runs location-based coordinate calculation (LBCC) algorithm. LBCC finds the expected coordinates of each node and probable location area with the expected coordinates as centre. Flooding DoS attack by the attacker is restricted at the AP using node’s probable location area. The method is validated by simulation experimentations with varying topologies. Further, geometrical analysis of the method is also provided.
