Hi3: An efficient and secure networking architecture for mobile hosts

The Host Identity Indirection Infrastructure (Hi3) is a networking architecture for mobile hosts, derived from the Internet Indirection Infrastructure (i3) and the Host Identity Protocol (HIP). Hi3 has efficient support for secure mobility and multihoming, which both are crucial for future Internet applications. In this paper, we describe and analyze Hi3 in detail. Compared to existing solutions, Hi3 achieves better resilience, scalability, and security. Both our analysis and early measurements support the notion that Hi3 preserves the best of both approaches while improving performance compared to i3 and enhancing flexibility and security compared to HIP.

The Smart-M3 Platform: Experience of Smart Space Application Development for Internet of Things

Efficient resource utilization in the Internet and in appearing Internet of Things (IoT) environments needs “smart applications”. They operate over shared resources of the computing environment to construct services sensitive to the users and their needs. Smart spaces support services that actively involve surrounding digital devices and Internet services. In this paper, we consider the Smart-M3 platform—an open source solution for creating smart spaces with ontology-driven information sharing. This study makes a next step for evolving smart space application development. We systemize the key properties for application development using Smart-M3 in IoT settings. The properties are analyzed on selected use cases, covering such emerging IoT application domains as collaborative work and e-Tourism. Our experimental evaluation confirms the applicability of analyzed solutions for today’s computing environments.

Virtual shared workspace for smart spaces and M3-based case study

Lack of practical development platforms and specific methods of application programming delays extensive real-life deployment of smart spaces. Virtual shared workspace is a reasonable scenario for evaluation of the smart spaces paradigm maturity. In this paper we consider SmartRoom system, which is Smart-M3 based open source implementation of virtual shared workspaces. Such collaboration activity as conference or meeting is performed in a room equipped with computing and presentational devices as well as accessing Internet services. Personal mobile devices are primary tools for users. Although the Smart-M3 platform is still a research prototype we show that its existing capability is sufficient for developing certain services for practical use. Functionality of SmartRoom services is not finely tuned and not strictly limited by activity domain. Advanced service construction with context awareness, personalization, and augmentation is possible. We illustrate these properties by introducing e-Tourism services for use in SmartRoom collaborative activity.

Service Intelligence Support for Medical Sensor Networks in Personalized Mobile Health Systems

Mobile health (m-Health) scenarios form an important direction for enhancing “traditional” healthcare systems. The latter implement backend services for use primarily by medical personnel and typically at hospitals. Current development meets with the challenge of personal data inclusion to the whole healthcare system with subsequent “smart” service construction and delivery. This paper makes a step towards the concept development of intelligence support in personalized m-Health systems. We study a reference architectural model that aims at intelligent utilization of personal mobile data in generic health services. Each personalized m-Health system contains the patient’s medical sensor network (MSN). To support the service intelligence we employ the smart spaces paradigm with its prominent technologies adopted from the Internet of Things (IoT) and Semantic Web.

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.

Digital assistance services for emergency situations in personalized mobile healthcare: Smart space based approach

Recent progress in technologies of the Internet of Things (IoT) enables advanced scenarios for mobile healthcare (m-Health). In this paper, we consider the service intelligence in m-Health (so called smart services). On the one hand, such a service utilizes the telemedicine approach when existing healthcare services (located in hospital) are delivered to remote patients (out of hospital). On the other hand, construction and delivery of a smart service benefit from additional intelligence attributes, beyond a fixed set of healthcare services of a given medical information system. For this promising class of m-Health services, we introduce reference scenarios of personalized assistance for a mobile patient with focus on emergency cases. Our development employs the smart spaces paradigm: patients, medical personnel, healthcare services, and other participants operate within a common networked computing environment and interact by sharing information and its semantics. We contribute design solutions to construct services as smart m-Health spaces.

Hierarchical architectures in structured peer-to-peer overlay networks

Distributed Hash Tables (DHT) are presently used in several large-scale systems in the Internet and envisaged as a key mechanism to provide identifier-locator separation for mobile hosts in Future Internet. Such P2P-based systems become increasingly complex serving popular social networking, resource sharing applications, and Internet-scale infrastructures. Hierarchy is a standard mechanism for coping with heterogeneity and scalability in distributed systems. To address the shortcomings of flat DHT designs, many hierarchical P2P designs have been proposed over recent years. The last generation is hierarchical DHTs (HDHTs) where nodes are organized onto layers and groups. This article discusses hierarchical architectures applied in structured P2P overlay networks, focusing on HDHT designs. We introduce a framework consisting of conceptual models of network hierarchy, multi-layer hierarchical DHT architectures, principles affecting the design choices, and cost models for system tradeoff analysis, performance evaluation, and scalability estimation. Based on the framework we provide a taxonomy and survey more than 20 hierarchical HDHT proposals.

On the Smart Spaces Approach to Semantic-Driven Design of Service-Oriented Information Systems

Smart spaces define a development approach to creation of service-oriented information systems for computing environments of the Internet of Things (IoT). Semantic-driven resource sharing is applied to make fusion of the physical and information worlds. Knowledge from both worlds is selectively encompassed in the smart space to serve for users’ needs. In this paper, we consider several principles of the smart spaces approach to semantic-driven design of service-oriented information systems. The developers can apply these principles to achieve such properties as (a) involvement for service construction many surrounding devices and personal mobile devices of the user, (b) use of external Internet services and data sources for enhancing the constructed services, (c) information-driven programming of service construction based on resource sharing. The principles are derived from our experience on the software development for such application domains as collaborative work, e-tourism, and mobile health.

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.

Development of smart room services on top of Smart-M3

SmartRoom is a system supporting collaboration activities localized in a room: a set of digital services is available for organizers and participants. The Smart-M3 platform is used to set up a networked knowledge sharing environment on top of which the SmartRoom service set is deployed. In this paper we introduce the methodology and design of the SmartRoom system. We consider realization of digital environment in a room, service set structure and corresponding Smart-M3 based computing infrastructure, ontological models and their use for service construction and delivery.
