Context-aware systems offer entirely new opportunities for application developers and for end users by gathering context data and adapting systems' behavior accordingly. In this paper, we propose a Context Aware ESB (CA-ESB) that will publish and discover services based on location context. The main modules of the framework consist of Context Provider (senses location context), Context Aware Logic...
Context is important situational details, yet poorly utilized in interactive computing. The fact is that it can have impact on the trust decision to make. Motivated by that, we discuss and formalize functions of dynamic trust computation model based on context-aware in P2P environments. We firstly present the definition of context-aware and trust, and then give the trust computation including directed...
By utilizing various sorts of contextual data acquired from the users' devices, advance context-aware services and applications can be developed. But the current context management systems are based on server-client approach which hinders their widespread adoption in an ad-hoc network. In addition, performance issues introduced because of context dependency in a ubiquitous environment still need to...
With rapid progress on ubiquitous technologies, various services become available at anytime and anywhere. One of hot topics in ubiquitous computing is context-aware services, which provide the services at proper time and proper place, in a proper way personalized to a user. However, there may be conflicts of services among users whose contexts are overlapped. Moreover, a context-aware service convenient...
The increasing popularity of personal wireless devices has raised new demands for the efficient discovery of heterogeneous devices and services in pervasive environments. The existing syntactic level service matching mechanisms such as Jini, UPnP, etc., are limited to syntactic comparisons based on attributes or interfaces. In order to overcome the limitations in these approaches, there has been an...
Conflict Resolution in context-aware computing is getting more significant attention from researchers as ubiquitous computing environments take into account multiple users. For multi-user ubiquitous computing environments, conflicts among users' contexts need to be detected and resolved. For this, application developers or end-users specify conflicts situations, and the underlying ubiquitous computing...
