| 摘 要： | 针对移动云计算中的虚拟机(virtual machine,VM)调度问题,考虑无线带宽限制对VM调度的影响,以云提供商的系统效益为目标函数,根据拍卖机制提出了一种带宽受限的VM动态调度(bandwidth constrainted VM dynamic scheduling,BVMDS)算法。该算法首先根据用户的出价来判定拍卖成功方,然后根据拍卖成功方对计算资源的需求来配置VM,最后采用临界支付的方式来计算拍卖成功方的实际支付价格。仿真结果表明,算法能够有效地改善云提供商的系统效益和资源利用率。

| Abstract: | Aiming at the problem of virtual machine (VM) scheduling in the mobile cloud computing, a novel Bandwidth constrainted VM dynamic scheduling (BVMDS) algorithm considering wireless bandwidth constraints is proposed to improve the benefit of cloud providers. The proposed algorithm is implemented by 3 phases. Firstly, the proposed algorithm determines the winning users based on the bids of users by the auction mechanism. Secondly, it configures VMs according to the information reported by the winning bidder. Thirdly, the payment for the winning users is determined in terms of the critical payment. The experimental results show that this new scheduling algorithm effectively improves the benefit and the resource utilization of cloud providers. |
