Definitions
Denial-of-service (DoS) attacks on Wi-Fi networks aim at crippling or completely blocking Wi-Fi links. Such attacks can be very efficient with the energy expenditure of the adversary being orders of magnitude lower than the communicating nodes. The most efficient attacks are cross-layer and combine vulnerabilities from the physical, medium access control, and link layers.
Background
Wi-Fi communications are defined by a family of protocols standardized as IEEE 802.11 (IEEE 802.11 Working Group, 2016). The standards recognize the importance of security and as such include various mechanisms for authentication, confidentiality, and integrity protection. These mechanisms underwent several improvements to address the vulnerabilities exposed by the research community. Wi-Fi protocols encompass several mechanisms to mitigate non-malicious interference and adapt to changes in the propagation environment such as carrier sensing, collision...
