Caching is an effective way to reduce peak-hour network traffic congestion by storing some
contents at user's local cache. Maddah-Ali and Niesen (MAN) initiated a fundamental study …

Caching is an efficient way to reduce peak hour network traffic congestion by storing some
content at the user's cache without knowledge of later demands. Recently, Maddah-Ali and …

Index coding is a canonical problem in network information theory that studies the
fundamental limit and optimal coding schemes for broadcasting multiple messages to …

A series of extensions of the index coding schemes based on time sharing by Birk and Kol,
by Blasiak, Kleinberg, and Lubetzky, and by Shanmugam, Dimakis, and Langberg are …

In this paper, we propose a new coding scheme and establish new bounds on the capacity
region for the multi-sender unicast index-coding problem. We revisit existing partitioned …

We consider a Multi-Sender Unicast Index-Coding (MSUIC) problem, where in a broadcast
network, multiple senders collaboratively send distinct messages to multiple receivers, each …

We establish new capacity bounds for the multi-sender unicast index-coding problem. We
first revisit existing bounds proposed by Sadeghi et al. and identify the suboptimality of their …

For a class of index coding problems with side information graph having the Ramsey
number R (i, j) upper bounded by ci ajb, it is shown that the clique covering scheme …

We extend the composite coding (CC) scheme for the index coding problem from two layers
to more layers of random binning. We explicitly introduce the three-layer composite coding …

Originally introduced to minimize the number of transmissions in satellite communication,
index coding is a canonical problem in network information theory that studies the …
