Context awareness is a key technology in pervasive computing. Quality of context (QoC) is a compound measurement to rate the potential correctness of a context value. The different physical sensors aggregated to infer a context, naturally have different update frequencies. However the only time related QoC parameter is “up-to-dateness”, which refers to the time passed since the value was collected. We propose to add “time locality” as new QoC parameter to express the time difference between… CONTINUE READING
