IoT6 is a research project on the future Internet of Things. It aims at exploiting the potential of IPv6 and related standards to overcome current shortcomings and fragmentation of the Internet of Things. The main challenges and objectives of IoT6 are to research, design and develop a highly scalable IPv6-based Service-Oriented Architecture to achieve(More)
IoT Lab is a European funded project researching the potential of crowdsourcing as an extension to the traditional IoT testbed infrastructures. The project proposes an innovative co-design, implementation and testing of solutions with the close involvement of the crowd in the process. Through the use of a smart phone application the crowd can participate in(More)
The detection of daily human activities is a key component in modern applications of Internet of Things. In this study, we introduce a hierarchical algorithm for online human activity detection with two levels of feature extraction methods. In the lower level, the algorithm gets sensor data from accelerometer and microphone of user smartphone and extracts(More)
Over the last few years the rise of cloud, mobile and social technologies has driven the influence of the Web into traditional value chains, digitizing many transactional and social interactions and opening up opportunities for new business models. At the same time new initiatives such as 6LoWPAN and CoAP are pushing the edges of the Web even further out,(More)
This article addresses a triple transition related to the emergence of the Internet of Things, IPv6 and cloud applications. It presents the potential use of IPv6 and CoAP to enable a global and scalable interconnection of the Internet of Things (IoT) together with the cloud, focusing on Software as a Service (SaaS). It presents a potential use of IPv6(More)
This article presents some key achievements and recommendations from the IoT6 European research project on IPv6 exploitation for the Internet of Things (IoT). It highlights the potential of IPv6 to support the integration of a global IoT deployment including legacy systems by overcoming horizontal fragmentation as well as more direct vertical integration(More)
This article presents some views on IoT, crowdsourcing and systemic risk management with a focus on smart cities. It starts by clarifying the notion of risk and risk management from ISO 31000 perspective It continues by presenting the IoT Lab European research project on crowdsourcing and Internet of Things (IoT), with an overview of its architecture and(More)
This article presents an initial set of results from the IoT Lab European research project on crowd sourcing and Internet of Things (IoT). It gives an overview of the IoT Lab architecture for IoT and crowd sourcing integration, including the use of IPv6 as a global integration enabler. It continues by presenting the IoT Lab specific research model enabling(More)
This paper presents the architecture of the crowdsourced experimental platform called IoT Lab. The platform will provide a new approach for experimentation by extending existing IoT FIRE testbeds, traditionally built from static sensor mote platforms, with crowd sourced resources and thus will enable richer and more distributed multidisciplinary experiments(More)
