Project technical objectives

• Develop a middleware for networked embedded systems based on a Service-oriented Architecture including:

- Support for distributed as well as centralised ambient intelligent architectures

- Support for reflective properties of components of the middleware

- Support for security and trust enabling components

• Develop a generic semantic model-based architecture supporting model-driven development of ambient intelligence applications.

Project technical objectives

• Tools for solutions providers, SDK

- Easy to integrate and use devices in applications

- Hide complexity of underlying network and device access protocols

- Integrated into familiar programming environments

• Tools for device manufacturers, DDK

- Low cost for networking devices

- Support for their devices to be part of an intelligent environment

P2P and SOAP Tunnelling

• P2P architecture for Device Networks

- Accessing and controlling devices irrespective of where they are

• P2P combined with Web Services

Semantic web based Self-Management in Hydra

• How to handle errors and device failures and other self-management properties, self-configuration/adaptation, self-protection…

• Extending context-awareness and to support Semantic Web-based (mainly SWRL rules), together with Genetic algorithms for planning

• Support QoS-awareness and Energy-awareness

Demonstration applications• Building Automation applications

- RF devices control at home (RF switches)- Weather information & forecast (Weather station)- Multimedia content control (UPnP AV)- CeBIT prototype

• e-Health applications- Reminders- Chat application (P2P, 3rd party application)- Weight scale monitoring (BT weigh scale)- Blood pressure monitoring (BT BPM)- Glucose metering (BT glucose meter)

• Agriculture applications- RFID stable control (RFID Testbed)- Integration with existing monitoring systems

Award winnings

• At the ICT Mobile Summit in Stockholm (June 10 - 12, 2008), the Hydra middleware for networked embedded systems was awarded the runner-up Best Demonstrator Award.

• Top 10 demonstration at ICT 2008 event in Lyon, France

• Pervasive services integration of devices for hetergenenious network and devices are successfull based on SOA architecture

• Semantic web technologies are important to achieve techinical goals of Hydra

• Hydra is under way of application in all 3 domains
