What are Pervasive Systems? Pervasive systems are systems composed of a network of collaborative sensing, computational and reasoning components that are highly embedded in the environment and actively – yet unobtrusively – interact with it. Embedding millions of networked smart sensing objects into an environment creates a digital skin which senses its immediate space. These massively distributed networks of smart objects communicate with one another, analysing and interpreting the immense amount of low-level spatio-temporal information about the physical objects and the environment, in order to produce a representation of the contextual situation and the existing environmental conditions.
Situated at the core of the Internet of Things, our research has high societal and economic impacts in various applications in the area of Smart Urban, Smart Life, and Smart Industry. This includes domains such as environmental monitoring, ecology, ambient assisted living, agriculture, transport and mobility, smart industry, supply chain management, wellbeing, health, sports, asset management, and predictive maintenance. Our system-oriented research is inspired by real problems, which makes multi-disciplinary collaboration natural.
Research challenges. For pervasive systems to become reality and effective, we need to address several research challenges. Such distributed networks of smart objects cooperate to support various applications as unobtrusively as possible (transparently, accurately, natural interacting), making efficient use of scarce resources independent of growth (scalability and interoperability), in such a way that the system adapts to a dynamically changing environment (evolvability, adaptability), and that operates and gives results that can be relied upon (trust, privacy, security). Mainly due to resource constraints, devices and connections are inherently unreliable, yet the system should be able to provide reliable services (quality, fault-tolerance, autonomy).
