The document outlines a functional model for Internet of Things (IoT) applications using a three-layer approach: application layer, IoT capabilities layer, and network layer. It mentions platforms such as Fiware and Universaal, which provide APIs for access to various IoT capabilities like federated identities and data brokers. It also raises a potential gap regarding the interaction between nomadic devices and cloud networks.

3. Architecture and Platforms
• Application A calls a FIWARE API for a
capability that is provided by a universAAL
platform: examples include federated
identities and authentication, data brokers,
etc.
• Potential gap?
