Abstract:
Context processing refers to the operation of processing different types of context data and/or information using different kinds of operators. These operators are applied according to some conditions or constraints given in context queries. Existing context aware systems process context data in a centralized fashion to answer context queries and generate context information. However, this method can cause scalability issues and give poor system throughput. In this paper, we aim to address this issue by proposing a distributed context data processing mechanism in which the context data processing computations of different context queries will be distributed to different computing devices. Relying on the developed prototype, a performance evaluation was conducted with centralized context data processing method as benchmark.
