Survey on Evaluation of Context Provisioning Middleware
نویسندگان
چکیده
In ubiquitous computing the provisioning of context-aware services is typically aided by a context provisioning middleware. The essential functionalities undertaken by the middleware include distributed data acquisition from sensors, context modelling, context synthesis, reasoning and context dissemination. This paper focuses on the evaluation methodologies of context-aware systems that aim to provide these functionalities and presents a holistic survey of existing work. Approaches of prototyping, field trials, emulation and simulation are presented. Further, we propose quantitative and qualitative evaluation metrics in order to allow for comparison of middleware based context-awareness approaches.

Performance simulation of a context provisioning middleware based on empirical measurements
The evaluation of context middleware systems is a challenging endeavour. On the one hand, testbed investigations suffer from an unrealistic environment in terms of number of users, high implementation effort for changes and questionable portability of results. On the other hand simulation of middleware systems is complex due to the high abstraction of implementation. This article contributes to...

متن کاملA Middleware with Comprehensive Quality of Context Support for the Internet of Things Applications
Context aware systems are able to adapt their behavior according to the environment in which the user is. They can be integrated into an Internet of Things (IoT) infrastructure, allowing a better perception of the user's physical environment by collecting context data from sensors embedded in devices known as smart objects. An IoT extension called the Internet of Mobile Things (IoMT) suggests n...
