Network Coding Based Multiple Fault Tolerance Scheme in P2P Cloud Storage System

Cloud storage systems are designed to provide reliable storage services and reduce the cost by utilizing the storage space efficiently. However, cloud storage systems suffer from loss of data whenever an unexpected failure occurs. This work focuses on providing network coding benefits in robust cloud storage system. We design a system model for multiple-cloud storage and multiple node failures. Further, the storage system provides authentication for users and minimizes the update operation. We have carried out our work considering trade-off between repair bandwidth and cloud storage capacity and comparing with RAID-6. The proposed approach provides protection (fault tolerance) against unexpected failure using erasure and regenerating codes.
