“…While we agree with the motivation and requirements presented in [7] (transparent monitoring of context, decoupled communication, scalability etc), our architecture goes a step further that context sensing abstraction, and not only provides a context model but also a set of abstractions to configure the contextdependent behaviour. From an architectural point of view, our work has been inspired in [1]: the sum of our micro-architectural decisions (such as using decorators or dependencies) also generates a flexible architecture.…”

In this paper we present the rationale and the main components for a modular and extensible architecture for building and deploying physical hypermedia software. We show that this kind of software systems poses strong requirements on supporting software (such as Web browsers) because they involve complex context-aware navigation semantics. By using some simple archetypical examples we also show how to provide context-aware assistance to the mobile user, as he explores the physical world.

“…Generalized software built to support context-aware computing in mobile environments has also become a focus of much research [18], [21], [43]. Among the best known systems is the Context Toolkit [43], which provides abstractions for representing context information through widgets that collect low-level sensor information and aggregate it into higher-level information more easily handled by application developers.…”

Abstract-Today's mobile applications require constant adaptation to their changing environments, or contexts. Technological advancements have increased the pervasiveness of mobile computing devices such as laptops, handhelds, and embedded sensors. The sheer amount of context information available for adaptation places a heightened burden on application developers as they must manage and utilize vast amounts of data from diverse sources. Facilitating programming in this datarich environment requires a middleware that provides context information to applications in an abstract form. In this paper, we demonstrate the feasibility of such a middleware that allows programmers to focus on high-level interactions among programs and to employ declarative abstract specifications of context in settings that exhibit transient interactions with opportunistically encountered components. We also discuss the novel context-aware abstractions the middleware provides and the programming knowledge necessary to write applications using our middleware. Finally, we provide examples demonstrating the flexibility of the infrastructure and its ability to support differing tasks from a wide variety of application domains.

Abstract. The increasing ubiquity of mobile computing devices has made mobile ad hoc networks an everyday occurrence. Applications in these networks are commonly structured as a logical network of mobile agents that coordinate with each other to achieve their goals. In these highly dynamic multi-agent systems, the multitude of devices provides a varied and rapidly changing context in which agents must learn to operate. Successful end-user applications will not only learn to handle dynamic conditions, but will take advantage of the wide variety of available information and resources. Any environment that supports agents and their interactions must facilitate flexible communication mechanisms. Such protocols for enabling an application agents task of gathering contextual information must function in a timely and adaptive fashion. This paper presents a protocol for mediating these context-based interactions among mobile agents. We present an implementation and show how it facilitates information exchange among mobile application agents. We also provide an analysis of the tradeoffs between consistency and range of context definitions in highly dynamic ad hoc networks.
