Secretive Coded Caching with Shared Caches
Shreya Shrestha Meel, B. Sundar Rajan
We consider the problem of \emph{secretive coded caching} in a shared cache setup where the number of users accessing a particular \emph{helper cache} is more than one, and every u…
Maddah-Ali-Niesen Scheme for Multi-access Coded Caching
Pooja Nayak Muralidhar, Digvijay Katyal, B. Sundar Rajan
The well known Maddah-Ali-Niesen (MAN) coded caching scheme for users with dedicated cache is extended for use in multi-access coded cache scheme where the number of users need not…
On the Optimal Broadcast Rate of the Two-Sender Unicast Index Coding Problem with Fully-Participated Interactions
Chinmayananda Arunachala, Vaneet Aggarwal, B. Sundar Rajan
The problem of two-sender unicast index coding consists of two senders and a set of receivers. Each receiver demands a unique message and possesses some of the messages demanded by…
Index Codes for Interlinked Cycle Structures with Outer Cycles
K. Vikas Bharadwaj, B. Sundar Rajan
Index code construction for a class of side-information graphs called interlinked cycle (IC) structures without outer cycles is given by Thapa, Ong and Johnson (C. Thapa, L. Ong, a…
Optimal Error Correcting Delivery Scheme for Coded Caching with Symmetric Batch Prefetching
Nujoom Sageer Karat, Anoop Thomas, B. Sundar Rajan
Coded caching is used to reduce network congestion during peak hours. A single server is connected to a set of users through a bottleneck link, which generally is assumed to be err…
