The complexity of developing and deploying context-aware pervasive-computing applications calls for distributed software infrastructures that unobtrusively support to contextual data collecting, information sharing and security privacy controlling. In this paper, we motivate a human-centric design for such an infrastructure to support context-aware applications. A novel peer to peer based semantic...
The increasing availability of sensing devices has made the possibility of context-aware pervasive computing applications real. However, constructing this software requires extensive knowledge about the devices and specialized programming languages for interacting with them. While the nature of pervasive computing lends users to demand individualized applications, complexities render programming embedded...
We identify here various kinds of failure conditions and robustness issues that arise in context-aware pervasive computing applications. Such conditions are related to failures in an application's interactions with ambient services, failures in resource discovery and binding, and invalidation of context conditions during the execution of an application task. In this paper we present an exception handling...
An infrastructure approach to support context-aware pervasive computing is advantageous for rapid prototyping of context-aware distributed applications and beneficial for unifying modelling of context and reasoning in uncertain conditions. This paper presents the ECORA framework for context-aware computing, which is designed with a focus on reasoning about context under uncertainty and addressing...
Context-aware pervasive computing application system should be flexibly adaptable to dynamic changes of context and application requirements and proactively provide the information satisfied with current context for users. The concept model and developing approach based on preference model presented by (K. Henricksen and J. Indulska, 2004) can satisfy the adaptation of context-aware pervasive computing...
Context-aware pervasive systems are emerging as an important class of applications. Such work attempts to recognize the situations of entities. This position paper notes three points when modelling situations: (1) there can be multiple ways to represent a situation; (2) a situation can be viewed as comprising relations between objects and so recognizing a situation boils down to determining if a prescribed...
