Challenges in Context-Aware Requirements Modeling: A Systematic Literature Review

Context-aware applications are becoming increasingly popular as they can adapt their behaviors to situations. However, the modeling of context-aware requirements is challenging owing to the inherent complexity and dynamicity of the context. Therefore, learning from existing studies can help academia and industry overcome the challenges. The primary objectives of this study are as follows: (1) survey the state-of-the-art of context-aware requirements modeling; (2) determine the challenges in context-aware requirements modeling and the extent to which the challenges have been addressed; (3) explore the future research directions of context-aware requirements modeling. We adopt the method of systematic literature review to retrieve relevant studies and extract available data aimed at the objectives. Seventy-two studies are finally selected. After data synthesis, we identify 4 categories of 13 challenges in context-aware requirements modeling. Based on the findings, we analyze the extent to which the challenges have been addressed and suggest future research directions.
