Replication and Migration Heuristics for Enhancing Service Accessibility in Fog Environment

Abstract

Fog computing has arisen to address the needs of IOT (Internet of Things) applications that are currently unmet by existing solutions. However, many issues associated with efficient and successful accessibility at service occur lead to interruptions and decrease the accessibility of services. In this paper, we introduce two fog service migration methods, which allow users to retrieve service in an efficient way, to improve service accessibility by replicating service on fog nodes. In these two methods,we take into account the service history from fog to each service, we also show the results of simulation experiments regarding the performance evaluation of our proposed heuristics.
