Abstract
Appropriate containers are deployed to cope with new request arrivals at Fog Computing (FC) hosts. In the case, we can consider two scenarios: (1) the requests may be queued until sufficient resources are prepared for the container deployments; (2) FC hosts may transfer arrived service requests to nearby FC hosts when they cannot accommodate new container deployments due to their limited or insufficient resources. Herein, for more employed neighboring FC hosts, arrived service requests may experience shorter waiting time in container deployment queue of each FC host. In contrast, they may take longer transfer time to pass through increased number of FC hosts. For this reason, there exists a trade-off relationship in the container deployment time depending on the number of employed FC hosts accommodating service request arrivals. Consequently, we numerically analyze the trade-off relationship to employ optimal number of neighboring FC hosts.
