As devices in the IoT are increasing in number and capabilities, there is an opportunity of creating networks of smart devices that go beyond the current cloud-centric model of data-gathering and actuation. The Swarm project provides a middleware to create a bio-inspired distributed and organic network of heterogeneous devices. Under the context of the Swarm project, in this thesis, we aim to create a framework for the interaction of devices, consisting of registration in the network, discovery, composition, and mediation of services. Using semantics as a driving technique, we aim to create a communication framework that facilitates the development of IoT applications in the Swarm, as a first step towards constructing a smart self-organizing network for the future IoT. The proposed framework aims to overcome the problems of interoperability and composition by adapting lightweight open standards with a service-oriented architecture and novel composition and mediation mechanisms. To illustrate the use of our framework, we implemented a use case based on the recruiting of services for a surveillance system. The significant contributions of this thesis can be summarized as: an architecture and implementation for device interaction in the IoT, a lightweight model for semantic service description and semantic querying, a ranking algorithm for service selection in an economy-based IoT network, an ontology for IoT services, and a declarative composition and mediation. To evaluate our work, we used two methods. First, we performed a quantitative comparison between an implementation with and without the use of our framework, then, we conduct a qualitative comparison of features offered by our framework with other similar works.
