Security scheduling of grid tasks based on a discrete particle swarm algorithm. (Chinese. English summary) Zbl 1240.68035
Summary: For the lack of safety studies in task scheduling in heterogeneous grid environments, a security benefit function is constructed taking into consideration performance requirements such as confidentiality, integrity, authenticity, etc. A dynamic method to evaluate the credibility of nodes and a new discrete particle swarm optimization algorithm are proposed. Experiments and comparisons with the particle swarm optimization algorithm in continuous space and a genetic algorithm show that the proposed algorithm has a faster convergence speed, a shorter scheduling length, and a higher safety performance.
