Performance Scalability Study of the Smart-M3 CuteSIB Implementation

According to the M3 architecture (multidevice, multivendor, multidomain), a smart space is created by deploying a Semantic Information Broker (SIB) in a given Internet of Things (IoT) environment. The deployed SIB enables information sharing for all digital devices participating in the IoT environment. In this study, we consider CuteSIB—a new SIB implementation for the Smart-M3 platform, where the class of SIB host devices covers such Qt-based equipment as common computers (e.g., laptops and personal computers), embedded computers (e.g., single-board computers and wireless routers), and personal mobile computers (e.g., smartphones and tablets). Our study focuses on performance evaluation of the CuteSIB operation with a multitude of devices that simultaneously participate in data sharing, information processing, and service delivery. Our simulation experiments applies a scalability model for a smart space application with the three functional groups of participating devices: sensors, reasoners, and mobile clients. In the experiments, the number of devices is varied in each group as well as the parameters of interaction behavior with SIB. The evaluation shows the scalability level that CuteSIB can achieve being deployed on a host device of moderate capacity in an IoT environment.
