Tools and Concepts for Communication and Networked Systems–Or: How to build resilient IoT Systems?

摘要: The Internet of Things (IoT) and related future networking concepts promise the ubiquitous availability of data. Applications can aggregate and evaluate relevant sets of data, and they can provide highly flexible, context-aware services, which can interact with each other and form a new type of emergent behavior.The first part of the story has already become reality. Sensors aggregating current values as well as data storages providing historical information emerge wildly around us in terms of computational capacity and data quantity. But did we already achieve the goals from an application and coordination point of view? Embedded, low performance IoT devices transmit their data periodically or event-driven to a database that serves the applications’ requests. By separating data producers from recipients, the traditional approach limits the flexibility and efficiency of the system. In contrast, accessibility and controllability of the IoT nodes immediately by (multiple) applications ensure a finely tuned configuration of individual embedded systems as well as the whole network. It will no longer be valuable to restrict IoT systems to static behavior, thus new methods, models, and algorithms are required to ensure functionality, resiliency, and security.
