“…Rist [15] proposes a technical solution to accessing a virtual meeting place through highly heterogeneous devices based on the development of device-specific user interface proxies not unlike the approach we have chosen here. Roman et al [16] also explores the challenges of integrating a PDA in a distributed environment. They argue the importance of using PDAs as enabling bridges to services rather than treating the PDAs as isolated entities.…”

Abstract. This paper presents results from a research project aiming at developing an architecture supporting local mobility within hospitals. The architecture developed is based on fieldwork and design workshops within a large Danish hospital and it has been implemented, put into a pilot phase, and evaluated. Our fieldwork has emphasised the differences between remote mobility, where users travel over long distances, and local mobility, where users walk around within a fixed set of buildings and/or places. Based on our field studies and our design work, we conclude that local mobility puts up three requirements for computer support; (i) it should integrate into the existing infrastructure, (ii) it should support the use of various heterogeneous devices, and (iii) it should enable seamless application roaming between these devices. The paper describes how these requirements were realized in a architecture for local mobility, and how this architecture was implemented in the healthcare domain.

“…CORBA provides primitives for discovering, managing, and communicating among distributed objects. For lightweight devices, we use the Universal Interoperable Core (UIC), which provides a lightweight, efficient implementation of basic CORBA services [16], which enable commodity devices to participate in pervasive computing. The secure publishsubscribe channels are implemented above CORBA event channels [14].…”

“…One way to address this is to restrict existing systems and provide only a functional subset (e.g. [18], [27], [28]) leading to different programming models or a subset of available interoperability protocols. Another option is to structure the middleware in multiple components, such that unnecessary functionality can be excluded from the middleware dynamically.…”

Pervasive computing environments add a multitude of additional devices to our current computing landscapes. Specialized embedded systems provide sensor information about the real world or offer a distinct functionality, e.g. presentation on a "smart wall". Spontaneous networking leads to constantly changing availability of services. This requires middleware support to ease application development. Additionally, we argue that an extensible middleware platform covering small embedded systems to full-fledged desktop computers is needed. Such a middleware should provide easy-to-use abstractions to access remote services and device-specific capabilities. We present a micro-broker-based approach which meets these requirements by allowing uniform access to device capabilities and services through proxies and the integration of different interoperability protocols. A minimum configuration of the middleware can be executed on embedded systems. Resource-rich execution environments are supported by the extensibility of the middleware.
