In a distributed storage system, code symbols are dispersed across space in nodes or
storage units as opposed to time. In settings such as that of a large data center, an important …

Erasure codes, such as Reed-Solomon (RS) codes, are increasingly being deployed as an
alternative to data-replication for fault tolerance in distributed storage systems. While RS …

The traditional means of ensuring reliability in data storage is to store multiple copies of the
same file in different storage units. Such a replication strategy is clearly inefficient in terms of …

Motivated by emerging applications to the edge computing paradigm, we introduce a two-
layer erasure-coded fault-tolerant distributed storage system offering atomic access for read …

Large Scale distributed storage systems play a vital role in maintaining data across storage
locations globally. These systems use replication as the default mechanism for providing …

Modern distributed storage systems often store redundant data in multiple replications or
erasure coding according to their access frequencies. Multiple replications scheme is well …

Cloud service providers (CSPs) promise to reliably store repositories outsourced by clients.
Unfortunately, once files have left the client's control, he has no means to verify their …

Erasure code-based distributed storage systems are increasingly being used by storage
providers for big data storage since they offer the same reliability as replication with a …

In this paper, we introduce two classes of optimal codes,[$2^ k-1$, k, $2^{k-1} $] simplex
codes and [$2^ k-1+ k $, k, $2^{k-1}+ 1$] codes, attaining Griesmer bound with equality. We …

Big-data systems enable storage and analysis of massive amounts of data, and are fueling
the data revolution that is impacting almost all walks of human endeavor today. The …
