DELIVERABLE D4.4 - Data aggregation toolkit and control middleware that integrates social collaboration and sensing environments

The present document is a deliverable of the SatisFactory project, funded by the European Commission’s Directorate-General for Research and Innovation (DG RTD), under its Horizon 2020 Research and innovation programme (H2020), describing the new architecture, improved design, current development status, and prototype implementation of LinkSmart middleware and its core services. It outlines a new architectural approach for different usage and deployment scenarios. It follows a detailed description of the proposed design and core middleware services and their interfaces. An event aggregation component for storing devices and services notifications into CIDEM repository service is also presented. Furthermore, an introduction to available Smart Sensor Networks (sensors, wearable devices, etc.) is given; corresponding Device Managers and their integration with middleware for event notification and collaboration are briefly explained.
