Covert Multi-Hop Communications for Heterogeneous Networks With Multiple Wardens
Justin H. Kong, Terrence J. Moore, Fikadu T. Dagefu
This paper investigates covert multi-hop communications in heterogeneous wireless networks monitored by multiple passive wardens. To maximize network-wide covertness while satisfyi…
Optimal Routing and Link Configuration for Covert Heterogeneous Wireless Networks in the Presence of a Friendly Jammer
Amna Gillani, Beatriz Lorenzo, Majid Ghaderi +3
In modern radio networks, nodes frequently access multiple communication interfaces such as WiFi, cellular, LoRa, and Zigbee. Optimal utilization of such heterogeneous networks (He…
Covert Routing with DSSS Signaling Against Cycle Detectors
Swapnil Saha, Rahul Aggarwal, Fikadu Dagefu +4
This paper investigates covert multi-hop communication in wireless networks where an adversary employs a cyclostationary (cycle) detector to reveal hidden transmissions. The covert…
Simultaneous Multi-Modal Covert Communications: Analysis and Optimization
Justin H. Kong, Terrence J. Moore, Fikadu T. Dagefu
This paper investigates the problem of covert communications in a heterogeneous wireless network where multiple communication modalities are used simultaneously. In this setup, a l…
FLARE: A Wireless Side-Channel Fingerprinting Attack on Federated Learning
Md Nahid Hasan Shuvo, Moinul Hossain, Anik Mallik +2
Federated Learning (FL) enables collaborative model training across distributed devices while safeguarding data and user privacy. However, FL remains susceptible to privacy threats…
Link-Sharing Backpressure Routing In Wireless Multi-Hop Networks
Zhongyuan Zhao, Yujun Ming, Ananthram Swami +3
Backpressure (BP) routing and scheduling is an established resource allocation method for wireless multi-hop networks, noted for its fully distributed operation and maximum queue s…
