Dynamic replication algorithms aim at allocating, migrating and deleting copies of an object over various Internet hosts, according to the access patterns exhibited online, so as ...
In this paper, we present an efficient algorithm for managing replicated data. We impose a logical tree structure on the set of copies of an object. In a failurefree environment t...
This work presents a proposal to diagnose distributed systems utilizing model-based diagnosis using distributed databases. In order to improve aspects as versatility, persistence,...
Secret sharing algorithms have been used for intrusion tolerance, which ensure the confidentiality, integrity and availability of critical information. However, dynamically changi...
All previous multicopy algorithms require additional space for redundant information equal to the size of the object being replicated. This paper proposes a new multicopy algorith...
