Real-Time and IoT – Why and How?

摘要

If visions and forecasts of industry come true then billions of interconnected embedded devices will soon surround us. We have the legitimate expectation that the individual devices as well as the overall system behaves in a reliable and predictable manner. We expect correct and timely results from sensing, computation, communication and actuation due to economic importance or even catastrophic consequences if the overall system is not working correctly. It will be argued that one of the major reasons for unpredictable and unwanted behavior of IoT systems is due to interference from external or internal processes. We need novel architectural concepts, an associated design process and validation strategies to satisfy the strongly conflicting requirements and associated design challenges of platforms for IoT: handle at the same time limited available resources, adaptive run-time behavior, and predictability. The presentation will introduce recent advances in this direction.
