Erasure Codes for Cold Data in Distributed Storage Systems

open access: yesApplied Sciences, 2023
Replication and erasure codes are always used for storing large amounts of data in distributed storage systems. Erasure code technology can maximize the storage space of distributed storage systems as well as guaranteeing their availability and ...

An Ant Colony Optimization Based Data Update Scheme for Distributed Erasure-Coded Storage Systems

open access: yesIEEE Access, 2020
Owing to the high availability and space-efficiency of erasure codes, they have become the de facto standard to provide data durability in large scale distributed storage systems.

Hierarchical erasure correction of linear codes [PDF]

open access: yesFinite Fields and Their Applications, 2020
Linear codes over finite extension fields have widespread applications in theory and practice. In some scenarios, the decoder has a sequential access to the codeword symbols, giving rise to a hierarchical erasure structure. In this paper we develop a mathematical framework for hierarchical erasures over extension fields, provide several bounds and ...

An Optimal Recovery Approach for Liberation Codes in Distributed Storage Systems

open access: yesIEEE Access, 2020
To reduce the storage cost, distributed storage systems are gradually using erasure codes to ensure data reliability. Liberation codes, which satisfy the maximum distance separable (MDS) property and provide optimal modification overhead, are a class of ...

Efficient erasure correcting codes [PDF]

open access: yesIEEE Transactions on Information Theory, 2001
Summary: We introduce a simple erasure recovery algorithm for codes derived from cascades of sparse bipartite graphs and analyze the algorithm by analyzing a corresponding discrete-time random process. As a result, we obtain a simple criterion involving the fractions of nodes of different degrees on both sides of the graph which is necessary and ...

Codes with locality for two erasures [PDF]

open access: yes2014 IEEE International Symposium on Information Theory, 2014
In this paper, we study codes with locality that can recover from two erasures via a sequence of two local, parity-check computations. By a local parity-check computation, we mean recovery via a single parity-check equation associated to small Hamming weight.

Performance Analysis and Design of LT Codes Under the Gaussian Elimination Algorithm in Wireless Sensor Networks

open access: yesIEEE Access, 2019
With the growing demand, wireless sensor networks (WSNs) play an increasingly important role in many fields. The focus has been on deploying Luby transform (LT) codes in WSNs because of their inherent advantages in erasure channels.

On erasure combinatorial batch codes

open access: yesAdvances in Mathematics of Communications, 2018
Combinatorial batch codes were defined by Paterson, Stinson, and Wei as purely combinatorial versions of the batch codes introduced by Ishai, Kushilevitz, Ostrovsky, and Sahai. There are $n$ items and $m$ servers, each of which stores a subset of the items. A batch code is an arrangement for storing items on servers so that, for prescribed integers $k$
