Local partial clique covers for index coding

A Agarwal, A Mazumdar - arxiv preprint arxiv:1603.02366, 2016 - arxiv.org
Index coding, or broadcasting with side information, is a network coding problem of most
fundamental importance. In this problem, given a directed graph, each vertex represents a …

Local partial clique and cycle covers for index coding

A Agarwal, A Mazumdar - 2016 IEEE Globecom Workshops …, 2016 - ieeexplore.ieee.org
We present a generalized novel upper-bound (and encoding scheme)-in the form of the
minimum value of a linear program-for optimal index coding. Our scheme combines the …

Linear programming approximations for index coding

A Agarwal, L Flodin, A Mazumdar - IEEE Transactions on …, 2019 - ieeexplore.ieee.org
Index coding, a source coding problem over broadcast channels, has been a subject of both
theoretical and practical interests since its introduction (by Birk and Kol, 1998). In short, the …

Independent user partition multicast scheme for the groupcast index coding problem

P Krishnan, V Lalitha - 2016 IEEE International Symposium on …, 2016 - ieeexplore.ieee.org
An index coding problem with n messages has symmetric rate R if all n messages can be
conveyed at rate R. In a recent work, a class of index coding problems for which symmetric …

[PDF][PDF] Design and Analysis of Efficient Index Coding Methods for Future Wireless Communications
