Abstract

The popularization of Fog Computing has provided the foundation for a computational environment better suited to applications demanding low communication latency. However, Fog environments has limited resources and restricted coverage areas, besides the user mobility that needs continuous migrations to maintain accessible and nearby content. To enable applications to harness the low latency offered by Fog, it is crucial to develop migration strategies capable of addressing the complexities of the Fog environment while ensuring content availability regardless of user location. This work proposes CMFogV, a proactive content migration strategy that leverages mobility prediction in a multi-level fog. Our results show that CMFogV is able to provide enhanced flexibility in the migration decision process across a wide diversity of scenario.

CMFogV:多级雾计算的主动内容迁移
雾计算的普及为建立更适合要求低通信延迟的应用的计算环境奠定了基础。然而,雾环境的资源有限,覆盖范围受限,而且用户流动性大,需要不断迁移以保持内容的可访问性和邻近性。为使应用程序能够利用雾环境提供的低延迟,关键是要制定迁移策略,既能解决雾环境的复杂性,又能确保内容的可用性,而不受用户位置的影响。本研究提出了 CMFogV,这是一种利用多级雾中移动性预测的主动内容迁移策略。我们的研究结果表明,CMFogV 能够在多种场景下为迁移决策过程提供更高的灵活性。

期刊介绍: As envisioned by Mark Weiser as early as 1991, pervasive computing systems and services have truly become integral parts of our daily lives. Tremendous developments in a multitude of technologies ranging from personalized and embedded smart devices (e.g., smartphones, sensors, wearables, IoTs, etc.) to ubiquitous connectivity, via a variety of wireless mobile communications and cognitive networking infrastructures, to advanced computing techniques (including edge, fog and cloud) and user-friendly middleware services and platforms have significantly contributed to the unprecedented advances in pervasive and mobile computing. Cutting-edge applications and paradigms have evolved, such as cyber-physical systems and smart environments (e.g., smart city, smart energy, smart transportation, smart healthcare, etc.) that also involve human in the loop through social interactions and participatory and/or mobile crowd sensing, for example. The goal of pervasive computing systems is to improve human experience and quality of life, without explicit awareness of the underlying communications and computing technologies. The Pervasive and Mobile Computing Journal (PMC) is a high-impact, peer-reviewed technical journal that publishes high-quality scientific articles spanning theory and practice, and covering all aspects of pervasive and mobile computing and systems.
