EHEFT-R: multi-objective task scheduling scheme in cloud computing

Abstract In cloud computing, task scheduling and resource allocation are the two core issues of IaaS layer. Efficient algorithm can improve matching efficiency between tasks resources. this paper, an enhanced heterogeneous earliest finish time based on rule (EHEFT-R) is proposed to optimize execution efficiency, quality service (QoS) energy consumption. EHEFT-R, ordering rules priority constraints used initial solution, (HEFT) ensure global performance solution space. Simulation experiments verify effectiveness superiority EHEFT-R.
