Wireless communications that use a shared Radio Frequency (RF) medium are often vulnerable to Denial of Service (DoS) attacks. Wireless Local Area Networks (WLAN) based on the IEEE 802.11 standard are no exception. In addition to brute force Physical (PHY) layer jamming attacks, WLANs are susceptible to various Media Access Control (MAC) vulnerabilities that can lead to DoS. This paper provides an overview of various WLAN DoS scenarios and available countermeasures to detect and mitigate them.
