Cost performance of QoS Driven task scheduling in cloud computing

Till now many parameters considered in QoS driven like makespan, latency and load balancing. But allocation cost parameter is not considered in QoS-driven scheduling algorithm. Minimizing the total allocation cost is an important issue in cloud computing. In this paper, the cost is calculated of QoS-driven task scheduling algorithm and compare with traditional task scheduling algorithm in cloud computing environment. The experimental results based on cloudsim3.0 toolkit with NetBeans IDE8.0 shows that QoS-driven achieves good performance in cost parameter. (C) 2015 The Authors. Published by Elsevier B.V.
