Bounding multiple unicasts through index coding and locally repairable codes

K Shanmugam, AG Dimakis - 2014 IEEE International …, 2014 - ieeexplore.ieee.org
We establish a duality result between linear index coding and Locally Repairable Codes
(LRCs). Specifically, we show that a natural extension of LRCs we call Generalized Locally …

Sending perishable information: Coding improves delay-constrained throughput even for single unicast

CC Wang, M Chen - IEEE Transactions on Information Theory, 2016 - ieeexplore.ieee.org
This paper considers network communications under a hard timeliness constraint, where a
source node streams perishable information to a destination node over a directed acyclic …

acyclic graph, where the sender and receiver of each unicast session are both connected to …

The two-unicast problem

S Kamath, V Anantharam, D Tse… - IEEE Transactions on …, 2016 - ieeexplore.ieee.org
We consider the communication capacity of wireline networks for a two-unicast traffic
pattern. The network has two sources and two destinations with each source communicating …

An edge reduction lemma for linear network coding and an application to two-unicast networks

An achievable region for the double unicast problem based on a minimum cut analysis

S Huang, A Ramamoorthy - IEEE transactions on …, 2013 - ieeexplore.ieee.org
We consider the multiple unicast problem under network coding over directed acyclic
networks when there are two source-terminal pairs, s 1-t 1 and s 2-t 2. The capacity region …

On the multiple-unicast capacity of 3-source, 3-terminal directed acyclic networks

We consider the multiple-unicast problem with three source-terminal pairs over directed
acyclic networks with unit-capacity edges. The three s it i pairs wish to communicate at unit …

Delay-constrained unicast and the triangle-cast problem

C Chekuri, S Kamath, S Kannan… - 2015 IEEE International …, 2015 - ieeexplore.ieee.org
We consider the single-unicast communication problem in a network with a delay constraint.
