Mobility-induced Service Migration in Fog Computing Environments
The emergence of fog computing has brought computation capabilities towards the edge of the network to support the needs of latency-intolerant services. Fog computing is designed to complement and not to replace cloud computing. Connecting users continuously with their desired services is the most important prerequisite of the fog computing paradigm. As these services are consumed mostly by mobile end users, therefore, the services must be kept close to the users characterized by mobility, to ensure the quality of services. The inherent nature of mobility demands that services be migrated with the users to ensure consistent optimal quality. Studies have emerged to address the issue of service migration in fog computing. This paper aims to bring together studies on service migration approaches in fog computing. Finally, based on the study of the current state of literature, a list of gaps and future opportunities have been identified and presented in this paper.
