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…
On Network Simplification for Gaussian Half-Duplex Diamond Networks
Martina Cardone, Christina Fragouli, Daniela Tuninetti
This paper investigates the simplification problem in Gaussian Half-Duplex (HD) diamond networks. The goal is to answer the following question: what is the minimum (worst-case) fra…
On Secure Network Coding for Two Unicast Sessions
Gaurav Kumar Agarwal, Martina Cardone, Christina Fragouli
This paper characterizes the secret message capacity of three networks where two unicast sessions share some of the communication resources. Each network consists of erasure channe…
Simplifying Wireless Social Caching
Mohammed Karmoose, Martina Cardone, Christina Fragouli
Social groups give the opportunity for a new form of caching. In this paper, we investigate how a social group of users can jointly optimize bandwidth usage, by each caching parts…
