A Comparative Analysis of Context-Management Approaches for the Internet of Things

The Internet of Things (IoT) has gained much attention during the last decade. A novel aspect like context management is a fundamental requirement for development of such systems. In literature, there are different approaches enabling the context management for internet of IoT. This paper has both objectives: 1) firstly, it establishes a set of classification criteria: heterogeneity, mobility, the influence of the physical world, scalability, security, privacy, quality of context, autonomous deployment of entities, characterization multi scales, interoperability, context acquisition, context modeling, context reasoning, context distribution, design method, and tools of implementation; 2) secondly, it refers to the previous criteria to make a comparative study between the well known existing approaches.
