In this study, we consider cooperative regenerating codes for distributed storage systems.
Cooperative regenerating codes are a class of codes that enable a data collector to reconstruct
the original data by connecting to a subset of storage nodes, and also can repair multiple failed nodes
by downloading data from the surviving nodes and exchanging data among the new nodes.
In cooperative regenerating codes, there exists a tradeoff between the storage size of each node and repair-bandwidth.
In this study, we propose new classes of cooperative regenerating codes based on correlation of information stored on
nodes. We also consider relationships between each class of cooperative regenerating codes and storage size and repair-bandwidth. |
