26. Future Agenda

27. Reliable Networked Sensing Systems? • The ability of a system or component to perform its required or designated functions under stated conditions for a specified period of time. • Key issues: complexity – resources – power – interaction • Non-iterative design process for networked systems • Predictable results • Reduction/capping of efforts required • Increasing the quality of the design • Full end-to-end validation • Today a cumbersome and error prone process – if at all possible • Many processes cannot be accelerated/synthesized

28. A Vision of Future WSN Design Methodology... • (Live) back annotation into the design space • „Closed loop“ system design • Including live data from simulation, testbeds, deployments • Allowing to refine and check architectural decisions, models, algorithms and implementations... Design Flow

29. A Facetted Yet Focused Systems Research Agenda • System architecture, software and models • TinyOS, BTnodes, BTnut • Low-power protocols • Test and validation methods • DSN testbed, deployment tools • Multi-context tracing • Sensor network deployments • Design methodology, platform kit • Smart Buildings, PermaSense Architecture Testing Applications

30. Accomplishments – The Bottom Line • Maybe not the most impressive publication list but predominantly at the premiere conferences. • An impressive network of people, contacts and consultancies. • A systems research agenda based on collaboration across disciplines and institutional borders. • Successful set of end to end systems implementations allowing sound reality checking.
