User-centric product recommendation on heterogeneous IoT device platform

Interoperability and functional redundancy between devices are important issues on IoT device group management because an IoT device group consists of diverse devices on heterogeneous platform. However, previous approaches for IoT device management are conducted from the perspective of the manufacture such as usage-based design and pre-sales analytics. In addition, product-based device management has a limitation in dealing with multifunctional smart devices and feature-reconfigurable devices on heterogeneous IoT environment. In this paper, we propose a user-centric approach for proactive product recommendation on heterogeneous IoT device platform. For the user-centric device management on heterogeneous platform, user and user group device profiles are integrated with feature-level device profiles which are owned by user and user group, respectively. The user’s application usage of feature level is visualized to the comparison through a circular-coordinate diagram. For the recommendation of new supplement and substitute devices, the device scores are calculated with the interoperability score, redundancy score, and superior score.
