Networked distributed data storage systems are essential to deal with the needs of storing massive volumes of data. Dependability of such a system relies on its fault tolerance (data should be available in case of node failures) as well as its maintainability (its ability to repair lost data to ensure redundancy replenishment over time). Erasure codes provide a storage efficient alternative to ...

Although there appears to be a broad recognition of the key role that Public Sector Information (PSI) can play in the development of societies, there are still significant gaps in our understanding of how PSI is actually being utilized and of its wider societal value, especially in developing countries.

Distributed data storage systems are essential to deal with the need to store massive volumes of data. In order to make such a system fault-tolerant, some form of redundancy becomes crucial. There are various overheads that are incurred due to such redundancy most prominent ones being overheads in terms of storage space and maintenance bandwidth requirements. Erasure codes provide a storage eff...
