Designing and Implementing Resilient IoT Applications in the Fog: A Smart Home Use Case

Abstract

Fog computing extends the capacities of the cloud to the edge of the network, near the physical world, so that Internet of Things (IoT) applications can benefit from properties such as short delays, real-time and privacy. Devices in the Fog-IoT environment are usually unstable and prone to failures. In this context, the consequences of failures may impact the physical world and can, therefore, be critical. This paper reports a framework for end-to-end resilience of Fog-IoT applications. The framework was implemented and experimented on a smart home testbed.
