Abstract

The major cause of threat circling around the wireless local area infrastructure network is Denial of Service (DoS) attack. The anticipated users will be denied from availing the resources by spoofing the Medium Access Control (MAC) address of the legitimate client/AP. Less protection in MAC address led to get easy spoofing. Since, the management frame has been unencrypted; adversary sends the management frame to the victim using the spoofed MAC address. This prerequisite goaded to offer an effective prevention mechanism for a DoS attack. Many security mechanisms are obtainable which have their own drawback in providing complete prevention of DoS attack. This paper proposes ThreV mechanism which detects and prevents the intruder in an efficient manner. The solutions are simulated using NS2, to analyze how far it prevents the DoS attacks. The simulation result of the proposed algorithm measures the packet delivery ratio, control overhead, normalized routing overhead, throughput, delay and packet loss. The experimental result proved the effectiveness of proposed ThreV algorithm in detecting and preventing MAC spoof DoS attacks.
