ABSTRACT

Recently, we have seen an increase of the use of Cloud computing to provide Modelling & Simulation services. In general, mobility support is lacking since clients normally contact the same centralised clouds regardless of their locations. In this research, we propose a method and algorithms to build Fogs as private services in which different middleware running in varied Virtual Machines (on various distributed Fogs and Cloud backbone) to expose different services. Clients access services via nearby Fogs, which then discover the required resources to run experiments (on Fogs or cloud backbone). Our focus is on mobility, to permit clients to conduct experiments (and visualise simulation results) using mobile devices. Mobility support is further improved by introducing the novel concept of a mobile simulation experiment: if a device moves away from a given Fog zone, the experiment moves with the device. We present a prototype implementation, evaluation results, and different case studies.

摘要

最近，我们看到越来越多地使用云计算来提供建模和仿真服务。一般来说，缺乏移动性支持，因为客户端通常会联系相同的集中式云，而不管其位置如何。在这项研究中，我们提出了一种将Fog构建为私有服务的方法和算法，其中不同的中间件在不同的虚拟机中运行（在各种分布式Fogs和云上）主干）以公开不同的服务。客户端通过附近的 Fogs 访问服务，然后发现运行实验所需的资源（在 Fogs 或云主干上）。我们的重点是移动性，允许客户使用移动设备进行实验（并可视化模拟结果）。通过引入移动模拟实验的新颖概念，进一步改进了移动支持：如果设备远离给定的雾区，则实验随设备一起移动。我们展示了原型实现、评估结果和不同的案例研究。
