A World of Opportunities: CPS, IOT, and Beyond

摘要

The continuous evolution of computing and networking technologies (e.g., Moore's Law) is creating a new world populated by many sensors on physical and social environments. This emerging new world goes much further than the original visions of ubiquitous computing and World Wide Web. Aspects of this new world have received various names such as Cyber Physical Systems (CPS) and Internet of Things (IOT). CPS links many physical sensor data to detailed simulation models running on large data centers. IOT brings together many appliances, making much more environmental data available and supporting control of these appliances. CPS/IOT applications are many, including personalized healthcare, intelligent transportation, smart grid, sustainable environment, and disaster recovery as representative examples. These CPS/IOT applications are motivated and strongly pushed by significant new social, economic, and human benefits. At the same time, these applications are also mission-critical with serious quality of service requirements such as real-time performance, continuous availability, high security and privacy. We will argue that the traditional process-oriented programming languages and software architectures should be augmented by distributed event-based facilities and abstractions for the construction of large scale distributed CPS/IOT applications. In addition to the focus on performance, we anticipate that other quality of service dimensions such as availability, reliability, security, and privacy will become important concerns in the research on distributed event-based systems. We will discuss research opportunities and challenges that bring the distributed event-based systems technology to CPS/IOT applications.
