“…In these cases, middleware should support applications' adaptation to the great variations of resources and services availability, by monitoring and pro-actively discovering resources, controlling the session, and changing the network connections or corresponding nodes. Also, context information may migrate with context-aware components (Henricksen et al, 2005).…”

Situated computing is an actual research area that gathers the knowledge and investigation in mobile, wearable, ubiquitous and augmented computing. The aim is to sustain systems that collect information about contexts and user actions over a period of time and supply it to applications that dynamically adapt to context changes. Situated computing systems have various architectures, but most of them include a middleware layer that supports equipment with limited computing resources and offers functionalities that simplify applications development, deployment, execution, and maintenance. Middleware and architectures are the focus of this paper, which presents the main concepts, research results, and future trends in middleware for situated computing. Service oriented, event driven, agent-based, and peer-to-peer architectures are discussed. Middleware issues for situated computing, embedded devices, autonomic space management, proactive services, context awareness, and smart spaces are tackled as well.

Abstract. More and more home devices are equipped with advanced computational capabilities to improve the user satisfaction (e.g., programmable heating system, Internet TV). Although these devices exhibit communication capabilities, their integration into a larger home monitoring system remains a challenging task, partly due to the strong heterogeneity of technologies and protocols. In this paper, we therefore propose to reconsider the architecture of home monitoring systems by focusing on data and events that are produced and triggered by home devices. In particular, our middleware platform, named DIGIHOME, applies i) the REST (REpresentational State Transfer) architectural style to leverage on the integration of multi-scale systems-of-systems (from Wireless Sensor Networks to the Internet) and ii) a CEP (Complex Event Processing) engine to collect information from heterogeneous sources and detect application-specific situations. The benefits of the DIGIHOME platform are demonstrated on smart home scenarios covering home automation, emergency detection, and energy saving situations.

“…This proxy is a representative of the context producing component and performs processing needed for maintaining the binding. Several context-aware middleware infrastructures [8,[21][22][23] offer context management functionality. Generally, this functionality enables context consumers to discover and bind to context producers using programming statements.…”

Abstract. Research in context-aware systems shows that using context information enables the development of personalized mobile applications. The context acquisition process in a context-aware (CA) system consists of two main roles: context producing entities (e.g. wrapped sensors) and context consuming entities (e.g. CA application). A CA system can be seen as a hierarchy of associated context producers and consumers which exchange contextual information. Managing contextual information used in context aware systems, introduces additional complexity for mobile application developers. We focus on the dynamic processes of discovery, selection, (re)binding and monitoring of entities that produce context information. Dynamic context binding is complex because of the dynamic nature, in terms of availability and quality, of context producers. We propose to delegate the responsibility for context binding to the middleware infrastructure and provide application designers with a declarative language to specify context information requirements on a high-level of abstraction. In this way, our Context-Aware Component Infrastructure (CACI) provides support for dynamic context bindings between application components and context producers.
