A Multi-Layer Framework for Quality of Context in Ubiquitous Context-Aware Systems
This paper proposes a novel framework for Quality of Context (QoC) in context-aware systems. The main innovative features include: (1) a new definition that generalizes the notion of QoC; (2) a novel multilayer context model; (3) a novel model of QoC that introduces new quality parameters; (4) a novel mechanism to define QoC policy by assigning weights to QoC parameters using a multi-criteria decision-making technique; (5) and a novel quality control algorithm that handles context conflicts, context missing values, and context erroneous values. Our frameworkis implemented in MatLab and evaluated using a case study of a flood forecast system.
