Interoperability Enhancement for Virtualization of Sensors for Smart Cities

Hiroyuki Maeomichi (NTT Network Innovation Laboratories, Japan); Akihiro Tsutsui (NTT Network Innovation Laboratories, Japan)

R0022292  We discuss interoperability enhancement for sensor virtualization for smart cities. We propose a model of metadata and data conversion components for interoperability enhancement and introduce our research approach.

Abstracting IoT Devices Using Virtual Machine for Wireless Sensor Nodes

In the field of IoT, abstracting of IoT devices is one of the important technologies. In order to abstract IoT devices, We have developed a virtual machine (VM) for wireless sensor nodes. Since the VM is based on Common Language Infrastructure of .NET Framework, users can develop a program on the IoT devices using Microsoft development environment (Visual Studio) and the languages such as Visual C# or C++. In addition, users can update the program on the IoT devices through the wireless sensor network. They don’t need to collect the sensor nodes in the environment for changing the behavior of the sensor network. In this paper, we introduce our sensor network system using the VM and the use cases.

ClouT: Cloud of Things for Empowering the Citizen Clout in Smart Cities

Kenji Tei (National Institute of Informatics, Japan); Levent Gurgen (CEA French Alternative Energies and Atomic Energy Commission, France)


ClouT is a collaborative project that leverages Cloud Computing as an enabler to bridge Internet of Things with Internet of People via Internet of Services. The project is based on a strong partnership of leading European and Japanese industry as well as universities and research centers. ClouT will have the following major outputs: i) a smart city infrastructure with a near to infinity processing and storage capacity of data from trillions of things and people that are integrated via virtual services in the Cloud while keeping their universal interoperability; ii) a set of platform level tools and services aiming at facilitating IoT application development, deployment and supervision iii) secure data access and processing mechanisms that can handle big data acquired from the heterogeneous sources in quasi real-time; iv) innovative city applications and field trials in four pilot cities: Santander and Genova in Europe, Mitaka and Fujisawa in Japan. Thus the ClouT project provides unified efforts on individual techniques, the whole vision integrating them, and attractive applications in cities.

Monitoring Dependability of City-scale IoT Using D-Case

Hideyuki Tokuda (Keio University, Japan); Takuro Yonezawa (Keio University, Japan); Jin Nakazawa (Keio University, Japan)


City-scale IoT, a fundamental infrastructure for smart cities, requires to sense a range of ubiquitous entities in a city including humans, objects, and spaces. Ubiquitous sensor networks (USN) is the key technology to this. However, failures of a USN may result in hazards in our daily lives in smart cities. Monitoring of USN, rapid detection of faults and failures, and recovery from them are thus important for better applications of USN. This paper proposes a means to do so comprehensively by using Dependability Cases (D-Case). Since USN is a system composed of variety of components such ash wireless sensor nodes, database servers, and network appliances, we need a tool that can target them in common. Our tool enables to execute monitoring programs on a D-Case diagram, which is represented with Goal Structuring Notation (GSN), so that it can target a variety of devices and services.

Internet of Things (IoT) is the set of technologies that can interconnect anything, from daily life objects to more sophisticated networked devices. The IoT paradigm is constantly increasing the number of devices owned by end-users. Following the social networks paradigm, IoT-centric social networks would allow sharing of devices between users that would provide useful information captured by sensor devices or giving ways to make remote actions on user devices. This paper proposes an IoT centric social device network based on a Cloud computing model which provides a virtual execution environment thanks to its decentralized nature, high reliability and accessibility from anywhere and at any time. The paper describes an approach that allows easily reusing highly distributed IoT resources by building services on top of them. Applications are built by composing those services and deploying into service platforms distributed and hosted in the Cloud that grants secure access to the data shared by these devices in compliance.

IoT and Cloud Convergence: Opportunities and Challenges

MD Abdur Rahim (Create-Net International Research Centre, Italy); Raffaele Giaffreda (Create-Net, Italy)

The success of the IoT world requires service provision attributed with ubiquity, reliability, high-performance, efficiency, scalability. In order to accomplish this attribution, future business and research vision is to merge the Cloud Computing and IoT concepts, i.e., enable an “Everything as a Service” model: specifically, a Cloud ecosystem, encompassing novel functionality and cognitive-IoT capabilities, will be provided. The introduction of cognition was the first step for the IoT success, as it brought essential self-management/awareness and knowledge-management functionality. Hence the paper will propose an innovative IoT centric Cloud smart infrastructure that will address the computational as well as IoT data management challenges in cloud through different services (e.g. devices as a services, infrastructure as a services and software as a services) at infrastructure and services levels.
