Fog Infrastructure and Service Management

Fog computing is emerging as complementary to cloud computing to realize deployment of large widely dispersed IoT devices, users, and corresponding applications. Management of resources and services is critical in widely dispersed fog environment with heterogeneous fog nodes to ensure its optimal utilization. Towards efficient management of fog, we proposed the Hierarchical and Autonomous Fog Architecture (HAFA) to organize heterogeneous fog nodes into a multi-layered connected hierarchy based on several parameters such as physical location, distance from IoT devices and/or users, node resource configuration, privacy and security. Simulations demonstrated the ease of search for an optimal fog node with required resource configuration towards deployment of application services. We have proposed a novel network-aware service pricing approach for Fog Infrastructure as a Service (FIaaS) environments. We are working on service management approaches to cater to the specific needs of fog environments.
