一种移动边缘计算中基于拍卖模型的服务迁移策略

A Service Migration Strategy Based on Auction Model in Mobile Edge Computing

在移动边缘计算中,目前对服务迁移策略的研究主要是集中在用户的服务质量方面,而对于服务提供商的收益情况没有足够重视。在论文中,引入了一级密封价格拍卖模型,在满足用户服务质量基础上,选择竞价最高的网络边缘节点进行迁移,从而使得服务提供商的收益最大化。文章的其余部分总结如下。首先,建立了关于时延、成本和收益的系统模型。然后,将系统模型转化为博弈论中的拍卖问题,通过求得贝叶斯纳什均衡解来获得最佳网络边缘节点。最后,就提出的迁移策略进行了模拟仿真,分析了提出的算法与已有算法的对比情况以及不同权重取值下的最优竞价。

In mobile edge computing,research work on service migration strategies is mainly focused on the user's service quality,while not paying enough attention to the benefits of service providers.In this article,it introduces the first price sealed auc-tion model,which selects the network edge node with the highest bidding price for migration on the basis of satisfying the user's ser-vice quality,so as to maximize the service provider's revenue.The rest of the article is summarized below.First,we established a system model about time delay and cost is established.Then,the system model is transformed into an auction problem in game theo-ry,and the best network edge node is obtained by obtaining the Bayesian Nash equilibrium solution.Finally,it conductes experi-ments on our proposed migration strategy,and analyzes the comparison between our proposed algorithm and the existing algorithm and the optimal bidding situation under different weights.
