Enforcing delay-aware fog-cloud based IoT firewall (Work In Progress)

Firewalls for IoT devices can be enforced at the gateway or at the cloud. Utilizing a fog based architecture, firewalls can also be enforced at fog layer. Depending on where the firewall is running, varying delays and overhead will be experienced by IoT devices. Some IoT devices are sensitive to the incurred delays. So choosing the most suitable platform to enforce firewall for each individual device under the different load conditions is important. In this work, we present a delay-aware IoT firewall enforcing mechanism using fog-cloud based architecture.
