Smart Spaces-Based Application Development

Smart spaces form now an emerging paradigm for application development in the various domains of ubiquitous, pervasive, mobile, embedded, and edge-centric computing. The smart space-based development still lacks matured methodologies appropriate for a wide range of application domains. The authors consider a particular class of smart spaces where interaction of many participants is information-driven and ontology-oriented using the indirect interaction models from multi-agent systems and knowledge manipulation technologies from the Semantic Web. The paper summarizes more than ten years of the authors' experience for this class of smart space-based application development. The M3 architecture (multidevice, multivendor, multidomain) for smart spaces enables concept development of service-oriented applications based on information sharing by software agents running on various devices and acting as knowledge processors. The Smart-M3 platform is an open source solution that implements the M3 architecture.

Smart-M3-based smart space creation using a DD-WRT-based device

Smart space is a service orientated infrastructure for knowledge sharing between devices. This paper describes a smart space creation process based on integration of Smart-M3 platform with DD-WRT-based device. Smart-M3 is an open source platform which implements the concept of smart space. Wi-Fi router was chosen as a DD-WRT-based device, which allows using it for smart space organization and provides wireless connection between devices at the same time. This method simplifies deployment of scenarios with several participants. The paper describes a process of compilation and installation of Smart-M3 platform to DD-WRT operating system. Testing of the main Smart-M3 operations showed that a smart space, organized in this way, can be used for considered scenarios. The authors have developed “Smart-M3 Control Panel” web-service which allows users to control the Smart-M3 platform by a graphical web interface. User of “Smart-M3 Control Panel” can view a current status of the platform; launch, stop or reload the platform; view information storage; download log files and change startup options. SocketIO protocol was used for user interaction with a web service.

A Substitution Algorithm for Dataflow Network Agents on Smart-M3 Platform

The paper presents an agent substitution algorithm for a dataflow network implemented on the Smart-M3 platform. Such a substitution allows to transfer control and computational context from an unexpectedly disconnected agent to a programmable substitute agent for the period of absence of the first agent in the network. It also guarantees integrity of the information flow, i.e. the functioning of all dependent services is not disrupted after the agent disconnection. When the agent returns to the network the reverse substitution occurs also with keeping integrity of the information flow. The paper gives a description of the dataflow network implementation and substitution mechanism structure on the Smart-M3 platform. The detailed description of the substitution algorithm including initialization, registration, and bidirectional substitution phases is given. The proposed substitution algorithm was implemented by the authors in the substitution mechanism as a part of the RedSIB semantic information broker on the Smart-M3 platform.

Concurrency Control in the Problem of Automatic Substitution of the Dataflow Network Agent on Smart-M3 Platform and in the Internet of Things

The paper describes implementation of dataflow networks based on Smart-M3 platform for use cases related to the Internet of Things. The mechanism for automatic substitution of computational agents created on top of Smart-M3 platform is described. The paper reviews concurrency issues of the developed solution regarding Smart-M3 platform, as well as in the broader context of the Internet of Things.

Smart Spaces Enabled Mobile Healthcare Services in Internet of Things Environments

The article studies the smart spaces approach applied for development of mobile healthcare (m-Health) services deploying in Internet of Things (IoT) environments. The authors consider a reference architecture model of the service ecosystem with focus on intelligent utilization of multi-source data originated from the IoT environment. Based on the architecture the authors introduce two reference scenarios: assistance in providing the first aid and communication with the hospital information system. For the architectural model and the scenarios pilot implementations are developed on the open source Smart-M3 platform.

Fault Tolerance Support for a Smart-M3 Application on the Software Infrastructure Level

The Smart-M3 platform allows constructing software applications consisting of agents that interact by sharing information in a smart space. An important problem is dependability of the application in case of failures, which is a common place for existing networked environments. In this paper, we consider a generic software infrastructure for Smart-M3 applications and propose two solutions to support the application fault tolerance. Our first solution is introduction of a content service, which provides safety of volumetric data and their integrity due to delegation of storage functions to a separate element of the application infrastructure. The second solution is mechanisms for network connections recovery. For experimental case study, we use an existing Smart-M3 application — the SmartRoom system. Based on this case we show effectiveness of the proposed solutions.

Subscription operation for applications in smart spaces of Smart-M3 platform

The paper considers the subscription operation for multi-agent application development on Smart-M3 platform. We systematize the algorithms of the basic subscription operation that Smart-M3 agents implement. The basic subscription operation uses the RDF representation model. Based on the systematization and taking into account the model-driven approach, we propose new subscription types that apply the OWL representation model. The proposed subscription types are implemented in SmartSlog SDK, resulting in compact application code that operates with high-level ontological terms (class, property, individual).

Intelligent system for conference management automation

Intelligent system for conference management automation is an interactive system for conferencing in a room equipped with two screens and facilities to project slides and other information on them. The first screen is used to display the speaker’s presentation, and the second screen is used for conference program visualization. The system is based on the Smart-M3 platform developed by the Nokia Research Center. Personal mobile devices (communicators, mobile phones, and personal computers) are used for interaction between users and the system. The appropriate software is installed on these devices. This article introduces the architecture and ontologies of the system's main components.

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.
