Locally Repairable Regenerating Code Constructions
Imad Ahmad, Chih-Chun Wang
In this work, we give locally repairable regenerating code (LRRC) [1]-[3], [5], [6] constructions that can protect the file size promised by the graph analysis of the modified fami…
When Can Helper Node Selection Improve Regenerating Codes? Part I: Graph-Based Analysis
Imad Ahmad, Chih-Chun Wang
Regenerating codes (RCs) can significantly reduce the repair-bandwidth of distributed storage networks. Initially, the analysis of RCs was based on the assumption that during the r…
Flexible Fractional Repetition Codes for Distributed Storage Networks
Imad Ahmad, Chih-Chun Wang
Consider the following fundamental question of distributed storage networks: Given any arbitrary values, whether there exists an intelligent helper selection scheme (assu…
Locally Repairable Regenerating Codes: Node Unavailability and the Insufficiency of Stationary Local Repair
Imad Ahmad, Chih-Chun Wang
Locally repairable codes (LRCs) are ingeniously designed distributed storage codes with a (usually small) fixed set of helper nodes participating in repair. Since most existing LRC…
When and By How Much Can Helper Node Selection Improve Regenerating Codes?
Imad Ahmad, Chih-Chun Wang
Regenerating codes (RCs) can significantly reduce the repair-bandwidth of distributed storage networks. Initially, the analysis of RCs was based on the assumption that during the r…
