Duong Tung Nguyen, Long Bao Le, Vijay Bhargava

摘要:

雾计算通过将存储、计算、控制和网络功能更接近最终用户、物联网和传感器,将网络边缘转变为智能平台。如何分配多种资源类型(例如,如何将容量有限的异构雾节点(如CPU、内存、带宽)公平有效地分配给具有不同需求和偏好的竞争服务是一项具有挑战性的任务。为此,我们提出了一种新的基于市场的资源分配框架,其中服务作为买方和雾资源作为可分割的商品在市场上。该框架的目的是计算市场均衡(ME)的解决方案,在每个服务获得其最喜爱的资源束下的预算约束,同时系统实现高资源利用率。这项工作扩展了一般均衡文献考虑满足效用函数的实际情况。此外,我们引进的概念,非浪费和节俭的均衡选择,并严格证明了所有的非浪费和节俭ME是凸规划的最优解。此外,建议的均衡具有显着的公平属性,包括嫉妒自由,分享激励,和比例。这项工作的另一个主要贡献是开发一个隐私保护的分布式算法,这是独立的利益,计算ME,同时允许市场参与者混淆他们的私人信息。最后,通过对系统进行广泛的性能评估,验证了理论分析的正确性.

英文摘要:

Fog computing is transforming the network edge into an intelligent platform by bringing storage, computing, control, and networking functions closer to end-users, things, and sensors. How to allocate multiple resource types (e.g., CPU, memory, bandwidth) of capacity-limited heterogeneous fog nodes to competing services with diverse requirements and preferences in a fair and efficient manner is a challenging task. To this end, we propose a novel market-based resource allocation framework in which the services act as buyers and fog resources act as divisible goods in the market. The proposed framework aims to compute a market equilibrium (ME) solution at which every service obtains its favorite resource bundle under the budget constraint while the system achieves high resource utilization. This work extends the General Equilibrium literature by considering a practical case of satiated utility functions. Also, we introduce the notions of non-wastefulness and frugality for equilibrium selection, and rigorously demonstrate that all the non-wasteful and frugal ME are the optimal solutions to a convex program. Furthermore, the proposed equilibrium is shown to possess salient fairness properties including envy-freeness, sharing-incentive, and proportionality. Another major contribution of this work is to develop a privacy-preserving distributed algorithm, which is of independent interest, for computing an ME while allowing market participants to obfuscate their private information. Finally, extensive performance evaluation is conducted to verify our theoretical analyses.
