Cooperative Local Repair in Distributed Storage
Ankit Singh Rawat, Arya Mazumdar, Sriram Vishwanath
Erasure-correcting codes, that support local repair of codeword symbols, have attracted substantial attention recently for their application in distributed storage systems. This pa…
Storage Capacity of Repairable Networks
Arya Mazumdar
In this paper, we introduce a model of a distributed storage system that is locally recoverable from any single server failure. Unlike the usual local recovery model of codes for d…
Compression in the Space of Permutations
Da Wang, Arya Mazumdar, Gregory Wornell
We investigate lossy compression (source coding) of data in the form of permutations. This problem has direct applications in the storage of ordinal data or rankings, and in the an…
On the Capacity of Memoryless Adversary
Arya Mazumdar
In this paper, we study a model of communication under adversarial noise. In this model, the adversary makes online decisions on whether to corrupt a transmitted bit based on only…
On a Duality Between Recoverable Distributed Storage and Index Coding
Arya Mazumdar
In this paper, we introduce a model of a single-failure locally recoverable distributed storage system. This model appears to give rise to a problem seemingly dual of the well-stud…
