Wireless Local Area Networks are susceptible to Denial of Service (DoS) attacks due to the broadcasting media of wireless networks. Management frames that carry the MAC address of the source are vulnerable to DoS attacks since they are sent without encryption. Among the different kinds of MAC layer DoS attacks, de-authentication/disassociation are found to be dreadful since they disconnect the user from the network. This paper focuses on the detection and prevention of different types of MAC layer DoS attacks. A framework with three proposed MAC layer security algorithms is designed to prevent the MAC layer DoS attacks. The various features of the proposed algorithms are compared with the existing mechanisms and the results are validated with a network simulator.
