Impact of Reflectors and MIMO on ML-Aided mmWave/sub-THz Blockage Prediction
Roghieh Mahdavihaji, Alexandra Duel-Hallen, Hans Hallen
The performance of millimeter-wave (mmWave) and sub-terahertz (sub-THz) communication systems is significantly impaired by sensitivity to sudden blockages. In this work, we employ…
Robust and Scalable Game-theoretic Security Investment Methods for Voltage Stability of Power Systems
Lu An, Pratishtha Shukla, Aranya Chakrabortty +1
We develop investment approaches to secure electric power systems against load attacks where a malicious intruder (the attacker) covertly changes reactive power setpoints of loads…
A Distributed and Resilient Bargaining Game for Weather-Predictive Microgrid Energy Cooperation
Lu An, Jie Duan, Mo-Yuen Chow +1
A bargaining game is investigated for cooperative energy management in microgrids. This game incorporates a fully distributed and realistic cooperative power scheduling algorithm (…
A Robust Stackelberg Game for Cyber-Security Investment in Networked Control Systems
Pratishtha Shukla, Lu An, Aranya Chakrabortty +1
We present a resource-planning game for cyber-security of networked control systems (NCS). The NCS is assumed to be operating in closed-loop using a linear state-feedback $\mathcal…
A Stackelberg Security Investment Game for Voltage Stability of Power Systems
Lu An, Aranya Chakrabortty, Alexandra Duel-Hallen
We formulate a Stackelberg game between an attacker and a defender of a power system. The attacker attempts to alter the load setpoints of the power system covertly and intelligent…
Game-Theoretic Mixed Control with Sparsity Constraint for Multi-agent Networked Control Systems
Feier Lian, Aranya Chakrabortty, Alexandra Duel-Hallen
Multi-agent networked control systems (NCSs) are often subject to model uncertainty and are limited by large communication cost, associated with feedback of data between the system…
Early Warning of mmWave Signal Blockage and AoA Transition Using sub-6 GHz Observations
Ziad Ali, Alexandra Duel-Hallen, Hans Hallen
The susceptibility of millimeter-wave (mmWave) signals to physical blockage and abrupt signal strength variations presents a challenge to reliable 5G communication. This work propo…
A Cyber-Security Investment Game for Networked Control Systems
Pratishtha Shukla, Aranya Chakrabortty, Alexandra Duel-Hallen
We formulate a resource-planning game between an attacker and a defender of a network control system. We consider the network to be operating in closed-loop with a linear quadratic…
Sparse Wide-Area Control of Power Systems using Data-driven Reinforcement Learning
Amirhassan Fallah Dizche, Aranya Chakrabortty, Alexandra Duel-Hallen
In this paper we present an online wide-area oscillation damping control (WAC) design for uncertain models of power systems using ideas from reinforcement learning. We assume that…
Distributed Multi-Step Power Scheduling and Cost Allocation for Cooperative Microgrids
Lu An, Jie Duan, Yuan Zhang +2
Microgrids are self-sufficient small-scale power grid systems that can employ renewable generation sources and energy storage devices and can connect to the main grid or operate in…
A Sensing Contribution-based Two-layer Game for Channel Selection and Spectrum Access in Cognitive Radio Ad-hoc Networks
Yuan Lu, Alexandra Duel-Hallen
In cognitive radio (CR) networks, the secondary users (SUs) sense the spectrum licensed to the primary users (PUs) to identify and possibly transmit over temporarily unoccupied cha…
Algorithms for Learning Sparse Additive Models with Interactions in High Dimensions
Hemant Tyagi, Anastasios Kyrillidis, Bernd Gärtner +1
A function is a Sparse Additive Model (SPAM), if it is of the form where $\mathcal{S}…
Adaptation to the Primary User CSI in Cognitive Radio Sensing and Access
Yuan Lu, Alexandra Duel-Hallen
In Cognitive Radio (CR) networks, multiple secondary network users (SUs) attempt to communicate over wide potential spectrum without causing significant interference to the Primary…
Channel-Adaptive Sensing Strategy for Cognitive Radio Ad Hoc Networks
Yuan Lu, Alexandra Duel-Hallen
In Cognitive Radio (CR) ad hoc networks, secondary users (SU) attempt to utilize valuable spectral resources without causing significant interference to licensed primary users (PU)…
CSI-aided MAC with Multiuser Diversity for Cognitive Radio Networks
Yuan Lu, Alexandra Duel-Hallen
Cognitive Radio (CR) aims to increase the spectrum utilization by allowing secondary users (SU) to access unused licensed spectrum bands. To maximize the throughput given limited s…
Enabling Adaptive Rate and Relay Selection for 802.11 Mobile Ad Hoc Networks
Neil Mehta, Alexandra Duel-Hallen, Wenye Wang
Mobile ad hoc networks (MANETs) are self-configuring wireless networks that lack permanent infrastructure and are formed among mobile nodes on demand. Rapid node mobility results i…
