ENABLING A FOG SERVICE LAYER WITH APPLICATION TO SMART TRANSPORT SYSTEMS

A fog service layer architecture is disclosed using hierarchical fog node deployment including the co-existence and interactions of the fog node with a cloud node. The architecture also includes a list of functions, capabilities or services that are hosted in each fog node. One or more fog management procedures may be run between fog nodes (or between fogs and the cloud) and may comprise a fog capability discovery procedure, a fog connection verification procedure, and a fog capability status report procedure. In addition, fog nodes may be configured to interact with each other to get particular services using one or more fog service procedures described herein.
