An SMDP Approach to Optimal PHY Configuration in Wireless Networks
Mark Shifrin, Daniel S. Menasché, Asaf Cohen +2
In this work, we study the optimal configuration of the physical layer in wireless networks by means of Semi-Markov Decision Process (SMDP) modeling. In particular, assume the phys…
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…
Covert Communication in the Presence of an Uninformed Jammer
Tamara V. Sobers, Boulat A. Bash, Saikat Guha +2
Recent work has established that when transmitter Alice wishes to communicate reliably to recipient Bob without detection by warden Willie, with additive white Gaussian noise (AWGN…
Optimal Dynamic Routing for the Wireless Relay Channel
Asaf Cohen, Dennis Goeckel, Omer Gurewitz +2
Consider a communication network with a source, a relay and a destination. Each time interval, the source may dynamically choose between a few possible coding schemes, based on the…
