Architecture-aware Coding for Distributed Storage: Repairable Block Failure Resilient Codes
Gokhan Calis, O. Ozan Koyluoglu
In large scale distributed storage systems (DSS) deployed in cloud computing, correlated failures resulting in simultaneous failure (or, unavailability) of blocks of nodes are comm…
Exploiting Full-duplex Receivers for Achieving Secret Communications in Multiuser MISO Networks
Berk Akgun, O. Ozan Koyluoglu, Marwan Krunz
We consider a broadcast channel, in which a multi-antenna transmitter (Alice) sends confidential information signals to legitimate users (Bobs) in the presence of eaves…
Centralized Repair of Multiple Node Failures with Applications to Communication Efficient Secret Sharing
Ankit Singh Rawat, O. Ozan Koyluoglu, Sriram Vishwanath
This paper considers a distributed storage system, where multiple storage nodes can be reconstructed simultaneously at a centralized location. This centralized multi-node repair (C…
Progress on High-rate MSR Codes: Enabling Arbitrary Number of Helper Nodes
Ankit Singh Rawat, O. Ozan Koyluoglu, Sriram Vishwanath
This paper presents a construction for high-rate MDS codes that enable bandwidth-efficient repair of a single node. Such MDS codes are also referred to as the minimum storage regen…
