Summary
Cyber-physical systems (CPS), tightly integrated with the physical environment through sensors and actuators, are expected to take digitalization to the next level. CPS will combine various sensor data and send it reliably and timely to servers performing big-data analysis to enable well informed decisions and to take relevant actions. Applications range from management of buildings to management of a self-driving car fleet and automation in factories. Ultra-reliable low-latency communication (URLLC) and resilience play key enabling roles for the communication part of a CPS. The main goal of this research project is to understand the fundamental end-to-end reliability and resilience and propose novel methods and protocols to enable those in practical CPS. The main objectives of the project will be carried out sequentially and will be: (i) develop methods for asserting reliability and resilience, as well as for predictive fault detection, (ii) develop novel features and algorithms for wireless communication that improve the reliability and resilience of CPS, (iii) propose and evaluate transport protocol improvements that facilitate URLLC, and (iv) carry out proof-of-concept demonstration of selected key solutions. The project will additionally strengthen the collaboration between KTH and Ericsson Research in an area of crucial importance for the Swedish industry and enable new knowledge generation and transfer through publications and patents.
Popular science description
Cyber-physical systems (CPS) are engineered systems that are built from computational algorithms and physical components that seamlessly interact. Advances in CPS will enable capability, adaptability, scalability, resiliency, safety, security, and usability that will far exceed the simple embedded systems of today. CPS technology will transform the way people interact with engineered systems -- just as the Internet has transformed the way people interact with information. It is expected that CPS will drive innovation in many sectors such as agriculture, energy, transportation, building design and automation, healthcare, and manufacturing. Despite significant research efforts into CPS technology in recent years, there exist no mature science to support systems engineering of high-confidence CPS. Today, there is a still lack of tools and methods that could manage the full complexity of CPS or adequately predict system behavior. For example, as the Internet of Things (IoT) scales to billions of connected devices -- with the capacity to sense, control, and otherwise interact with the human and physical world -- the requirements for security, safety, and privacy grow immensely. More importantly, traditional real-time performance guarantees are insufficient for CPS when systems are large and spatially and temporally distributed in configurations that may rapidly change. As the CPS get more autonomous, greater assurances of safety, security, scalability, and reliability are demanded. This project will contribute to the development of CPS to take the next step to establish true low-latency and highly reliable interactions among millions of connected devices. First, the project will investigate and propose practical methods for validating that a system is as reliable and resilient as required, thereby providing the society a solid foundation for trust in the systems. In the next step the project will propose solutions on how to improve the reliability and low-latency aspects relates to long term 5G evolution and will bring benefits in the form of more reliable and efficient CPS. The initial step will investigate and propose practical methods for validating that a system is as reliable and resilient as required, thereby providing the society a solid foundation for trust in the systems. Finally, the project will showcase the developed solutions in a demonstrator.
