The Sensor Internet, formed by the global interconnection of networked embedded sensing systems, will allow global online access to the state of the real world. While anticipated to enable a diversity of novel applications in areas of primary societal importance such as sustainable use of natural resources and energy, the Sensor Internet also poses a unique set of research challenges at the intersection of distributed and embedded systems: Despite severely constrained resources and unreliability of individual nodes and wireless communication, applications demand the Sensor Internet to be robust, scalable, and long-lived. Being deeply embedded into the real world, the Sensor Internet also needs to adapt to dynamically changing environmental and system parameters in a self-organizing manner. We argue that this inherent complexity necessitates novel abstractions that are tailored to the specific characteristics of the Sensor Internet. By enabling a declarative specification of the desired behavior of node ensembles, such abstractions can significantly simplify design and implementation of the Sensor Internet, while introducing only a modest runtime overhead. We illustrate the feasibility of this approach by means of an abstraction for design and implementation of self-organizing sensor networks

Kay Roemer is a senior researcher at the Institute for Pervasive Computing of ETH Zurich, where he leads research and teaching activities related to wireless sensor networks. Kay received his PhD from ETH Zurich with a thesis on sensor networks and helped shape the research community in this area by organizing several pertinent scientific events. Before moving to Zurich, Kay studied computer science at the University of Frankfurt in Germany, where he co-founded and led the MICO open source project, a middleware for distributed systems that is widely used in large-scale and mission-critical commercial applications. He has co-authored two books on this topic.
