Covert Single-hop Communication in a Wireless Network with Distributed Artificial Noise Generation
Ramin Soltani, Boulat Bash, Dennis Goeckel +2
Covert communication, also known as low probability of detection (LPD) communication, prevents the adversary from knowing that a communication is taking place. Recent work has demo…
Covert Communications on Poisson Packet Channels
Ramin Soltani, Dennis Goeckel, Don Towsley +1
Consider a channel where authorized transmitter Jack sends packets to authorized receiver Steve according to a Poisson process with rate packets per second for a time period $T…
Covert Communications on Renewal Packet Channels
Ramin Soltani, Dennis Goeckel, Don Towsley +1
Security and privacy are major concerns in modern communication networks. In recent years, the information theory of covert communications, where the very presence of the communica…
A Utility Optimization Approach to Network Cache Design
Mostafa Dehghan, Laurent Massoulie, Don Towsley +2
In any caching system, the admission and eviction policies determine which contents are added and removed from a cache when a miss occurs. Usually, these policies are devised so as…
Physical Layer Security in Heterogeneous Cellular Networks
Hui-Ming Wang, Tong-Xing Zheng, Jinhong Yuan +2
The heterogeneous cellular network (HCN) is a promising approach to the deployment of 5G cellular networks. This paper comprehensively studies physical layer security in a multi-ti…
