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…
Secure Group Testing
Alejandro Cohen, Asaf Cohen, Omer Gurewitz
The principal goal of Group Testing (GT) is to identify a small subset of "defective" items from a large population, by grouping items into as few test pools as possible. The test…
On Secrecy Rates and Outage in Multi-User Multi-Eavesdroppers MISO Systems
Joseph Kampeas, Asaf Cohen, Omer Gurewitz
In this paper, we study the secrecy rate and outage probability in Multiple-Input-Single-Output (MISO) Gaussian wiretap channels at the limit of a large number of legitimate users…
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…
