A Mobile Matchmaker for the Ubiquitous Semantic Web

The Semantic Web and Internet of Things visions are converging toward the so-called Semantic Web of Things (SWoT). It aims to enable smart semantic-enabled applications and services in ubiquitous contexts. Due to architectural and performance issues, it is currently impractical to use existing Semantic Web reasoners. They are resource consuming and are basically optimized for standard inference tasks on large ontologies. On the contrary, SWoT use cases generally require quick decision support through semantic matchmaking in resource-constrained environments. This paper presents Mini-ME, a novel mobile inference engine designed from the ground up for the SWoT. It supports Semantic Web technologies and implements both standard (subsumption, satisfiability, classification) and non-standard (abduction, contraction, covering) inference services for moderately expressive knowledge bases. In addition to an architectural and functional description, usage scenarios are presented and an experimental performance evaluation is provided both on a PC testbed (against other popular Semantic Web reasoners) and on a smartphone.

An Information Framework for Creating a Smart City Through Internet of Things

Increasing population density in urban centers demands adequate provision of services and infrastructure to meet the needs of city inhabitants, encompassing residents, workers, and visitors. The utilization of information and communications technologies to achieve this objective presents an opportunity for the development of smart cities, where city management and citizens are given access to a wealth of real-time information about the urban environment upon which to base decisions, actions, and future planning. This paper presents a framework for the realization of smart cities through the Internet of Things (IoT). The framework encompasses the complete urban information system, from the sensory level and networking support structure through to data management and Cloud-based integration of respective systems and services, and forms a transformational part of the existing cyber-physical system. This IoT vision for a smart city is applied to a noise mapping case study to illustrate a new method for existing operations that can be adapted for the enhancement and delivery of important city services.

An OSGi middleware to enable the Sensor as a Service paradigm

The Internet of Things vision has recently stimulated many research efforts in different communities. The collection of diverse information produced by the proliferation of inter-connected sensing entities is one of the biggest challenge that should be adequately addressed. The huge amounts of raw data produced by IoT devices need to be structured, stored, analysed, correlated and mined in a reliable and scalable way. The size of the produced data, and the high rate at which data are being produced, suggest that we need new solutions that combine tools for data management and services capable of promptly structuring, aggregating and mining data even just at the time they are produced. In this paper we propose a middleware, to be deployed on top of physical sensors and sensor networks, capable of abstracting sensor devices from their proprietary interfaces, and offering them to third party applications in an as-a-Service fashion for prompt and universal use. The middleware also offers tool to elaborate real-time measurements produced by sensors. A prototype of the middleware has been implemented. In the paper a real use case scenario is also discussed.

Security Issues and Challenges for the IoT-based Smart Grid

Internet of Things (IoT) is the next step evolution of our today Internet, where any physical object/thing having/equipped with computation and communication capabilities could be seamlessly integrated, at different levels, to the Internet. The Smart Grid (SG), which is considered as one of the most critical Infrastructures, is defined as the classical power grid augmented with a large-scale ICT and renewable energy integration, can be seen as one of the largest IoT network. The SG will involve billions of smart objects/things: smart meters, smart appliances, sensors, actuators-cars, etc. in addition to several communication infrastructures whether public (most often) or private. However, security is seen as one of the major factors hampering the rapid and large scale adoption and deployment of both the IoT vision and the Smart Grid.In this paper we investigate the security issues and challenges on the IoT-based SG, and define the major security services that we should consider when dealing with SG security

Extending the RPL Routing Protocol to Agricultural Low Power and Lossy Networks (A-LLNs)

The routing protocol for low power and lossy network (RPL) started to be designed by the ROLL working group of IETF since the year of 2008. Until the RFC6550 was released, this standard with its routing algorithms and four application scenarios, such as home and building automation, industrial control, and urban environment, have been grounded. As a main jigsaw of the paradigm of the Internet of Things (IoT), RPL plays the major role and has become an impressed technical tendency in the field of wireless communication. However, it is still very difficult to find effective approaches to simulate and evaluate RPL’s behaviors and other extensions of its applicability, especially in the domain of precision agriculture. Notice that wireless sensor network (WSN) has been deployed a wide variety of wireless sensing devices, and should be one valued supported part of the promising IoT ecosystem. In this paper, first the authors provide a brief presentation of the related protocols including their standardization, the existing implementations, and a group of simulation experiment results obtained from the RPL capable COOJA simulator with its developed modules. Second, the authors then focus on the utilization of this protocol in the agricultural low power and lossy network (A-LLN) area and propose their dedicated instances hybrid network architecture to meet its specific requirement. Moreover, the Web of things (WoT), a trend and new vision of IoT, is appended in the authors’ proposal to provide a novel dimension in design of A-LLN since it enables a full interoperability with current web application and higher efficiency of development. As a conclusion, the authors summarized their ongoing work and future solutions of the current technology issues.

Internet of Things (IoT): A vision, architectural elements, and future directions

Ubiquitous sensing enabled by Wireless Sensor Network (WSN) technologies cuts across many areas of modern day living. This offers the ability to measure, infer and understand environmental indicators, from delicate ecologies and natural resources to urban environments. The proliferation of these devices in a communicating–actuating network creates the Internet of Things (IoT), wherein sensors and actuators blend seamlessly with the environment around us, and the information is shared across platforms in order to develop a common operating picture (COP). Fueled by the recent adaptation of a variety of enabling wireless technologies such as RFID tags and embedded sensor and actuator nodes, the IoT has stepped out of its infancy and is the next revolutionary technology in transforming the Internet into a fully integrated Future Internet. As we move from www (static pages web) to web2 (social networking web) to web3 (ubiquitous computing web), the need for data-on-demand using sophisticated intuitive queries increases significantly. This paper presents a Cloud centric vision for worldwide implementation of Internet of Things. The key enabling technologies and application domains that are likely to drive IoT research in the near future are discussed. A Cloud implementation using Aneka, which is based on interaction of private and public Clouds is presented. We conclude our IoT vision by expanding on the need for convergence of WSN, the Internet and distributed computing directed at technological research community.

Special Issue on RFID - Towards Ubiquitous Computing and the Web of Things: Guest Editors´ Introduction

The Internet of Things (IoT) is emerging as the next technological revolution and with it opens up a new research field. In particular, this new field needs to be studied in conjunction with adequate theories, design principles, and user acceptance. As such, a number of technologies become relevant and intertwined with this new trend. In particular, IoT is an effort to reach out into the real world of physical objects. In this regard, technologies like Radio Frequency Identification (RFID), short-range wireless communications, Real Time Location Systems (RTLS), and sensor networks ubiquity contribute to make IoT vision, a reality [13]. Continuous improvements in technological performance, combined with maturing applications and decreasing prices have contributed to the pervasive adoption of Automated Identification Technology (AIT) such as bar codes and RFID technology. Following its incubation period, today RFID technology adoption can be seen in various domains making its diffusion global across industries and national borders. Over the last 10 years, RFID application is witnessing a significant growth in almost each sector. RFID Item-Level Tagging (ILT) initiatives are extensively deployed in sectors such as apparel and footwear - with companies such as Gerry Weber International, American Apparel, Macy, JC Penney, and Wal-Mart leading the movement.

Federated semantic nodes to scale search process in the IoT

The Internet of Things (IoT) refers to extending the Internet to heterogeneous components such as actuators, sensors or other smart devices. In this vision, the IoT foresees novel usage of such devices through applications enabling new device-device or device-people associations. Recent interest in providing digital extensions for these things has led to billions of connected devices offering their services or data through different platforms, some of them wrapped with semantic descriptions to realize aforementioned associations through accurate search processes. However, the ubiquitous aspect of the IoT and the potential mobility of the devices that compose it, prevent from adopting a centralized approach to search and manage these associations for scalability reasons. As devices composing the IoT are geolocalized, we believe that designing a framework composed of geographically distributed and cooperating nodes with local reasoning capabilities is a much more scalable approach to realize the IoT vision. We describe our approach of such vision by creating a federated network composed of such nodes that declare their location, process semantic descriptions of devices and share deduced associations with other peers that are selected based on their location nearness.

Technology classification, industry, and education for Future Internet of Things

SUMMARYThe Internet of Things (IoT) is developing rapidly and becoming a hot topic around the world. On the basis of the reorganized Unit IoT and Ubiquitous IoT, two models for Future IoT are proposed in this paper. A dimension model is established to classify the complicated IoT technologies and a layer model is built for Future IoT system architecture. Then, the IoT vision and its development phases prediction are presented. Furthermore, the thought of regarding IoT as an emerging industry is explained to be inappropriate because IoT is a new stage of intelligentization and informatization development. Meanwhile, the necessity of training qualified personnel in colleges is introduced. Then, the relation between IoT and the science and technology system and IoT relevant subjects is analyzed. At the end, this paper raises the problem of setting IoT as a major in college and proposes some suggestions. Copyright © 2012 John Wiley & Sons, Ltd.
