Study of thwarting DoS attacks by detecting MAC spoof in WLAN infrastructure networks

Abstract

Denial of Service (DoS) attacks is a major problem prevalent in Wireless Local Area Network. An attack occurs mainly because of Medium Access Control (MAC) address spoofing. MAC spoofing is a technique where an adversary pretends to be a legitimate client/Access Point (AP) and sends forgery frames to the victim client or AP. Most of existing solutions are prevent DoS attacks after an intruder sending forged frame by spoofing Client or AP's identity. Few solutions are exists to detect an attacker at the time of MAC address spoofing. None of these techniques provides a complete solution. This paper describes the existing solutions and drawbacks of the available solutions and also compares the existing technique with future work based on throughput, packet loss and end to end delay.
