The design of secure buffer managers for database systems supporting real-time applications with firm deadlines is studied here. We first identify the design challenges and then p...
In this paper a novel electronic payment protocol suitable for “peer-to-peer” (P2P) networks is presented. It implements electronic cash-based transactions, between buyers and...
Replication is a key mechanism to achieve scalability and fault-tolerance in databases. Its importance has recently been further increased because of the role it plays in achievin...
We introduce the first binary search tree algorithm designed for speculative executions. Prior to this work, tree structures were mainly designed for their pessimistic (non-specu...
This work extends the Particle Swarm Optimization (PSO) algorithm for working on dynamic environments. We propose an evaporation mechanism to solve the outdated memory problem. We...
