Consistency in the face of change: an adaptive approach to physical layer cooperation
Ayan Sengupta, Yahya H. Ezzeldin, Siddhartha Brahma +2
Most existing works on physical-layer (PHY) cooperation (beyond routing) focus on how to best use a given, static relay network--while wireless networks are anything but static. In…
A Polynomial-Time Algorithm for Pliable Index Coding
Linqi Song, Christina Fragouli
In pliable index coding, we consider a server with messages and clients where each client has as side information a subset of the messages. We seek to minimize the number o…
Making recommendations bandwidth aware
Linqi Song, Christina Fragouli
This paper asks how much we can gain in terms of bandwidth and user satisfaction, if recommender systems became bandwidth aware and took into account not only the user preferences,…
Network Simplification in Half-Duplex: Building on Submodularity
Martina Cardone, Yahya H. Ezzeldin, Christina Fragouli +1
This paper explores the {\it network simplification} problem in the context of Gaussian Half-Duplex (HD) diamond networks. Specifically, given an -relay diamond network, this pr…
On (Secure) Information flow for Multiple-Unicast Sessions: Analysis with Butterfly Network
Gaurav Kumar Agarwal, Martina Cardone, Christina Fragouli
This paper considers a class of wireline networks, derived from the well-known butterfly network, over which two independent unicast sessions take place simultaneously. The main ob…
Group secret key agreement over state-dependent wireless broadcast channels
Mahdi Jafari Siavoshani, Shaunak Mishra, Christina Fragouli +1
We consider a group of trusted and authenticated nodes that aim to create a shared secret key over a wireless channel in the presence of an eavesdropper Eve. We assume that…
