A Comparitive Study of the Available Solutions to Minimize Denial of Service Attacks in Wireless LAN

Denial of Service (DoS) attack is a major attack in Wireless Local Area Network. This paper studies the available solutions for Denial of Service (DoS) attacks and compares them with each other in a wireless infrastructure network. All these methods are used to minimize the DoS attacks. It discusses the Central Manager (CM), Medium Access Control Address Filtering (MAF) and Traffic Pattern Filtering (TPF) methods to avoid DoS attacks in Wireless Local Area Network (WLAN). Central Manager (CM) provides the better solution to avoid DoS attacks and it improves the performance of WLAN with the help of tables and timer. In the case of Transmission Control Protocol (TCP), MAF and TPF methods are used to detect and resolve Authentication Request Flooding (AuthRF) and Association Request Flooding (AssRF). This paper compares the performance of these two solutions based on throughput and the results are analyzed with the graphs.
