QoS Constrained Grid Workflow Scheduling Optimization Based on a Novel PSO Algorithm

Abstract: Currently, computational grid, service grid and data grid are becoming richer and more complex. Grid infrastructure composed of heterogeneous resource is widely distributed, workflow scheduling problem in grid environment described by directed acrylic graph (DAG) becomes an important and difficult problem. Meanwhile, the research on workflow scheduling problem in grid environment mainly focuses on the time and cost constrained optimization, but the key problems about stability, flexibility, security and load b… Show more

“…Notice that by ensuring the security of potential resources certainly decreases the possibility of being attacked and damaged to a great extent [89]. Similarly, security is considered as an important quality aspect of the cloud service that ensures their confidentiality by authenticating the parties involved, encrypting messages, and providing access control [49,79,90].…”

“…The drawback of this proposal is that the hillclimbing heuristic scans each particle which renders local search computation complex (Engelbrecht, 2005). Tao et al (2009) proposed RHDPSO and RCPSO (Tao et al, 2011b) to solve multi-QoS constrained grid workflow scheduling problem. PSO particles represent DAG task graphs; dimensions of a particle represent the tasks in the corresponding graph.…”
