Survey of efficient cloud storage method based on interference alignment
|
Abstract:
Cloud storage/distributed storage mainly depends on the storage redundancy and efficient nodes repair mechanisms to protect the reliability. In order to reduce the repair cost of bandwidth and storage space, the technology of interference alignment is used to fix the problem of repairing nodes in a cloud storage system. Interference alignment can compression interference data which used to repair nodes to smaller spatial dimensions, make the desired data dimensions that pending repair nodes required for be bigger, ensure high reliability while reducing repair cost, saving the cost of cloud storage. First this paper introduced the problems of repairing nodes in a distributed storage system. Then it elaborated the importance of interference alignment in distributed storage and domestic and international progress. Finally it analysed of the main problems and future research priorities.
