Machine Learning for Intrusion Detection into Unmanned Aerial System 6G Networks
… to block intercommunication among nodes by jamming attacks and violating integrity through executing spoofing attacks. This work offers a practical IDS onboard UAV intrusion detection system to detect unintentional interference, intentional interference jamming, and spoofing attacks. …

Providing availability in the lower layers of a wireless network: philosophies and case studies
… by defending against denial-of-service (DoS) attacks at the lower layers. Specifically, a network can 1. detect misbehaviors to eliminate DoS attacks; 2. enforce fairness to mitigate DoS attacks; or 3. adopt randomization to escape DoS attacks. For each philosophy, this dissertation presents a …

Secure protocols for wireless availability
… the MAC layer to perform a more power e fficient jamming attack. IFR-MAC nulli ffies the proactive attack of denial-of-service injection of false reservation control messages. Both SimpleMAC and IFR-MAC quickly outperform the Nash equilibrium of disabling MAC and converge to the capacity-optimal …

Visual Terrain Relative Navigation: Pose Estimation, Neural Fields, and Verification
… the possibility of signal loss or outside signal jamming attack. This thesis presents a threefold constribution to visual TRN. Firstly, due to the high altitude and high speeds of planetary TRN missions, acquiring non-simulation test data oftentimes proves difficult, and thus many datasets used to …

Antifragile Communications
Jamming is an ongoing threat that plagues wireless communications in contested areas. Unfortunately, jamming complexity and sophistication will continue to increase over time. The traditional approach to addressing the jamming threat is to harden radios, such that they sacrifice communications …

A Distributed Reinforcement Learning based Intelligent Routing and Beamforming Design for Robot-assisted Mobile Ad-hoc Network under Uncertain and Complex Environment
… in the more extreme case, under disturbance from attacker. 2) Under the background of harsh millimeter-wave (mmwave) communication, how to maximize the practical communication quality of multi-user mmWave MIMO systems with uncertain or interference environment through effectively using the …

Localizing Jammers in Wireless Networks
… cryptographic methods.</p> <p>One of the attacks that can easily imperil the availability of networks is jamming attacks. An adversary can launch a jamming attack either by bypassing MAC-layer protocols and keeping sending packets, or by emitting radio signals to a particular channel. To …

Security Enhanced Communications in Cognitive Networks
… radios allow more sophisticated reactive jamming attack, which imposes a serious threat to CR communications. By exploiting MIMO interference cancellation techniques, we propose jamming resilient CR communication mechanisms to survive in the presence of reactive jammers. Finally, we focus …

Alibi framework for identifying insider jamming attacks in half-duplex wireless local area networks
… networks, unfortunately, are vulnerable to radio jamming attacks (in short, ``jamming attacks'') due to the open and shared nature of wireless medium. In a jamming attack, an attacker injects a high level of noise into the wireless system which significantly reduces the signal-to-noise ratio …

Intelligent low-complexity widely deployable diagnostic tools for wireless edge device security using machine learning
… wireless networks remain susceptible to radio jamming. Modern stealthy attacks transmit short jamming signals that use little energy (to be more challenging to detect), yet cause entire packet transmission procedures to fail. This thesis concentrates primarily on wireless sensor networks (WSNs) …
