Suspicious Transactions in Smart Spaces

IoT systems have enabled ubiquitous communication in physical spaces, making them smart Nowadays, there is an emerging concern about evaluating suspicious transactions in smart spaces. Suspicious transactions might have a logical structure, but they are not correct under the present contextual information of smart spaces. This research reviews suspicious transactions in smart spaces and evaluates the characteristics of blockchain technology to manage them. Additionally, this research presents a blockchain-based system model with the novel idea of iContracts (interactive contracts) to enable contextual evaluation through proof-of-provenance to detect suspicious transactions in smart spaces

UNIVERSAL INFRASTRUCTURE OF M2M ENABLED INTER-CLOUD SERVICES FOR INTELLIGENT TRANSPORTATION SYSTEM

 The objective of this study is to develop the design of a generic infrastructure for on-demand applications for intelligent transport systems (ITS) in an urban area. The main idea of the study is to allow seamless service composition and consumption, but also to allow rapid deployment of new services through the pooling of different devices and access networks that may be owned and operated by different actors such as telecom operators, transportation service operators, governmental organizations, etc. This research serves the solution for the problem of interoperability between different devices, on the fly device reconfiguration and service discovery.

A Conceptual Framework for Addressing IoT Threats: Challenges in Meeting Challenges

The Internet of Things (IoT) is rapidly growing, and offers many economical and societal potentials and benefits. Nevertheless, the IoT also introduces new threats to our Security, Privacy and Safety (SPS). The existing work on mitigating these SPS threats often fails to address the fundamental challenges behind the mitigation measures proposed, and fails to make the relations between different mitigation measures explicit. This paper, therefore, offers a conceptual framework for understanding and approaching the challenges and obstacles that arise in addressing the SPS threats of the IoT. This contribution aims to help policymakers in adopting policies and strategies that stimulate others to develop, deploy and use IoT devices, applications and services in secure, privacy-friendly and safe ways

Internet of Things Applications as Energy Internet in Smart Grids and Smart Environments

Energy Internet (EI) has been recently introduced as a new concept, which aims to evolve smart grids by integrating several energy forms into an extremely flexible and effective grid. In this paper, we have comprehensively analyzed Internet of Things (IoT) applications enabled for smart grids and smart environments, such as smart cities, smart homes, smart metering, and energy management infrastructures to investigate the development of the EI based IoT applications. These applications are promising key areas of the EI concept, since the IoT is considered one of the most important driving factors of the EI. Moreover, we discussed the challenges, open issues, and future research opportunities for the EI concept based on IoT applications and addressed some important research areas

Using Battery-Less RFID Tags with Augmented Capabilities in the Internet of Things

Driven by user demand for new smart systems in the framework of the Internet of Things (IoT) and fueled by technological advances in Radiofrequency Identification (RFID), an increasing number of new IoT-oriented RFID-based devices has appeared in recent years in scientific literature. Some of them conjugate canonical RFID identification with extra functionalities such as sensing, reasoning, memorization, and actuation. In this way, IoT challenging applications can be developed, which distribute processing load till to the extreme nodes of the network, while lying upon the well-established RFID infrastructure. In this work, a reasoned panoramic on the potentialities in the IoT framework of augmented RFID tags is presented and classified. Two applicative scenarios are envisioned, presented and discussed, to illustrate how augmented RFID devices may support advanced IoT systems

Virtual Resources & Internet of Things

Internet of Things (IoT) systems mostly follow a Cloud-centric approach. These systems get the benefits of the extensive computational capabilities and flexibility of the Cloud. Although Cloud-centric systems support virtualization of components to interact with IoT networks, many of these systems introduce high latency and restrict direct access to IoT devices. Fog computing has been presented as an alternative to reduce latency when engaging IoT networks, however, new forms of virtualization are required to access physical devices in a direct manner. This research introduces a definition of Virtual Resources to enable direct access to IoT networks and to allow richer interactions between applications and IoT components. Additionally, this work proposes Virtual Resources as a mechanism to handle the multi-tenancy challenge that emerges when more than one tenant tries to access and manipulate an IoT component simultaneously. Virtual Resources are developed using Go language and CoAP protocol. This work proposes permission-based blockchain to provision Virtual Resources directly on IoT devices. Seven experiments have been done using Raspberry Pi computers and Edison Arduino boards to test the definition of Virtual Resources presented by this work. The results of the experiments demonstrate that Virtual Resources can be deployed across different IoT platforms. Also, the results show that Virtual Resources and blockchain can support multi-tenancy in the IoT space. IBM Bluemix Blockchain as a Service and Multichain blockchain have been evaluated handling the provisioning of Virtual Resources in the IoT network. The results of these experiments show that permission-based blockchain can store the configurations of Virtual Resources and provision these configurations in the IoT network

Blending Human Ware with Software and Hardware in the Design of Smart Cities

Sustainable innovation entails realizing society-oriented value creation in an environment-friendly manner. A smart city can be viewed as a holistic paradigm that avails of state-of-the-art information and communication technologies (ICTs, in other words) to advance the so-called “Internet of Things.” This aids the management of urban processes and improves the quality of life for the citizens. Smart cities are bound to keep getting “smarter” as the ICTs keep developing. While the technological factor represented by the IoT, augmented and virtual reality, artificial intelligence, urban digital twinning, cloud computing, and mobile Internet is a driving factor unarguably, innovation in urban ecology is a vital socio-economic factor that will spur the transformation of urban areas in the world to smart cities. In this chapter, the authors answer the “what,” how, and “who,” so to say, of the paradigm—smart cities—with real-life examples and a case study. They emphasize the importance of human ware and remind readers that technology—the all-encompassing Internet of Things with its infantry of cameras, sensors, and electronic devices—though powerful, is a humble servant in the service of the inhabitants of a smart city

Adding sense to the internet of things: an architecture framework for smart object systems

The Internet of Things (IoT) concept is being widely presented as the next revolution toward massively distributed information, where any real-world object can automatically participate in the Internet and thus be globally discovered and queried. Despite the consensus on the great potential of the concept and the significant progress in a number of enabling technologies, there is a general lack of an integrated vision on how to realize it. This paper examines the technologies that will be fundamental for realizing the IoT and proposes an architecture that integrates them into a single platform. The architecture introduces the use of the Smart Object framework to encapsulate radio-frequency identification (RFID), sensor technologies, embedded object logic, object ad-hoc networking, and Internet-based information infrastructure. We evaluate the architecture against a number of energy-based performance measures, and also show that it outperforms existing industry standards in metrics such as network throughput, delivery ratio, or routing distance. Finally, we demonstrate the feasibility and flexibility of the architecture by detailing an implementation using Wireless Sensor Networks and Web Services, and describe a prototype for the real-time monitoring of goods flowing through a supply chain.Tomás Sánchez López, Damith C.
