DOI: 10.1109/lcomm.2017.2695610

Abstract: This letter studies the performance of ensemble of Regenerating codes and Replication (RR). It theoretically analyzes the storage-bandwidth tradeoff curve of RR, and attains two extremal cases, corresponding to minimum storage cost RR (MSRR) and… read more here.

DOI: 10.1109/lcomm.2022.3230263

Abstract: In distributed storage systems (DSS), an optimal code design must meet the requirements of efficient local data regeneration in addition to reliable data retention. Recently, low-density parity-check (LDPC) codes have been proposed as a promising… read more here.

DOI: 10.1109/tcomm.2024.3490494

Abstract: Maximum distance separable (MDS) codes in distributed storage systems provide the optimal tradeoff between fault tolerance and storage overhead. As a kind of MDS codes, minimum storage regenerating (MSR) codes have attracted a lot of… read more here.

DOI: 10.1109/tit.2020.3008342

Abstract: We consider the problem of multiple-node repair in distributed storage systems under the cooperative model, where the repair bandwidth includes the amount of data exchanged between any two different storage nodes. Recently, explicit constructions of… read more here.

recommendations! Published in 2021 at "IEEE Transactions on Information Theory"

DOI: 10.1109/tit.2020.3036386

Abstract: In the literature, all the known high-rate MDS codes with the optimal repair bandwidth possess a significantly large sub-packetization level, which may prevent the codes to be implemented in practical systems. To build MDS codes… read more here.
