Recently, both academic and industrial organisations have worked on advanced computing systems. Even though the following collection of ubiquitous and pervasive initiatives is not exhaustive, it presents the most interesting and promising state-of-the-art devices, applications, and services. Many academic organisations all over the world have taken over various relevant projects during the last decade, like the Aura project 1 (Garlan et al 2002) of Carnegie Mellon University, which claims to introduce the concept of a 'personal information aura'-an invisible halo of computing and information services that persist regardless of location-that spans wearable, handheld, desktop and infrastructure computers. The MIT project Oxygen 2 (MIT 2003), enables pervasive, human

“…These concepts are focal and adequate to semantically represent any context information in pervasive environments. In Figure 2, the defined SCE subclasses are depicted along with their interrelations based on an extension of a preliminary approach presented in [4]. This class corresponds to all human entities and offers various datatype properties for incorporating the user related context.…”

A context ontology for pervasive service provision

Pervasive computing systems that strive to be minimally intrusive and exhibit inherent proactiveness and dynamic adaptability to the user preferences and environment need to be context-aware. Contextawareness provides computing environments with the ability to adapt the services or content they provide, by implicitly sensing and automatically deriving the users' needs from the context that surrounds them, making services more attentive, responsive and predictive. This paper is concerned with the development of an ambient context management system that aims to maximize the automation of the complete context knowledge lifecycle via the establishment of a flexible prototype context ontology 1 .

“…In general, a well-designed context model is a key factor in developing context-aware systems. Our experience [45], [46] indicates that context-aware application development requires significant and careful modelling efforts to ensure that context information is appropriately represented in the target context management system and that applications are able to perform valid manipulations on it. This section focuses on providing the basis for constructing a distributed, scalable, extensible and well performing context model in support of fully integrated context-aware services in large-scale pervasive environments.…”

COMPACT: Middleware for context representation and management in pervasive computing

Context awareness is one of the key aspects of pervasive computing systems. In such systems, a plethora of dynamic context information needs to be constantly retrieved, soundly interpreted, rapidly processed, maintained in various repositories, and securely disseminated. Thus, a flexible, scalable and interoperable context representation scheme needs to be established and solid context management mechanisms need to be adopted, which will perform well in large-scale distributed pervasive systems. This paper elaborates on the COMPACT context middleware that has been designed to cope with the issues above and saturate pervasive computing environments with context awareness functionality.
