Abstract
Regenerating codes are mainly justified due to their ability to reduce the repair bandwidth incurred by a newcomer node. This happens when a node fails or leaves the network, thus a new node is initiated, attempting to connect to existing nodes to reconstruct the data. This paper aims to investigate the case in which the newcomer can wisely select some of existing nodes to connect to, so as to reduce the repair bandwidth. Accordingly, selective regenerating codes are proposed, showing the corresponding repair bandwidth is dramatically reduced as compared to that of existing codes.
