Design of semantic information broker for localized computing environments in the internet of things

Emerging communication technologies of the Internet of Things (IoT) make all the devices of a spatial-limited physical computing environment locally interconnected as well as connected to the Internet. Software agents running on devices make the latter “smart objects” that are visible in our daily lives as real participating entities. Based on the M3 architecture for smart spaces, we consider the problem of creating a smart space deploying a Semantic Information Broker (SIB) in a localized IoT-environment. SIB supports agent interaction in the smart space via sharing and self-generating information and its semantics. This paper proposes a renewed SIB design with increased extensibility, dependability, and portability. The research done is a step towards an efficient open interoperability platform for the smart space application development

Proactive Personalized Mobile Multi-Blogging Service on Smart-M3

This paper discusses the project targeted in development of proactive, personalized and composite services for the blogosphere. By applying the smart spaces paradigm we have developed an approach for composition of blog spaces. We contribute formal technique for construction of proactive and personalized service for bloggers as well as for its integration with external applications. The proposed technique is implemented in SmartScribo application on top of the Smart-M3 platform. The developed prototype solution has confirmed that the approach results in services with the next quality level

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
