Towards an interoperability certification method for semantic federated experimental IoT testbeds

IoT deployments and then related experiments tend to be highly heterogeneous leading to fragmented and non-interoperable silo solutions. Yet there is a growing need to interconnect such experiments to create rich infrastructures that will underpin the next generation of cross sector IoT applications in particular as using massive number of data. While research have been carried out for IoT test beds and interoperability for some infrastructures less has been done on the data. In this paper, we present the first step of the FIESTA certification method for federated semantic IoT test bed, which provides stakeholders with the means of assessing the interoperability of a given IoT testbed and how it can be federated with other ones to create large facility for experimenter. Focus is given on data and semantic context of the test beds and how they can interoperate together for larger experiments with data

Utility Metrics Specifications. OpenIoT Deliverable D422

This deliverable specifies the utility metrics that are considered and used in the scope of the OpenIoT project. These utility metrics are recorded as part of the implementation of the Utility Manager component of the OpenIoT platform, while they have also been used to drive the utility based optimization mechanisms of the project. In particular we provided the following contributions: We provide an analysis and summary of utility metrics for different data providers and environments, including physical sensors, sensor networks, and virtual sensors. These metrics can be used to measure utility for interconnected objects. We proposed utility functions that use metrics in order to compute valuation and cost functions. These functions can be used by utility-based optimization techniques. The utility based schemes proposed provide means and algorithms that can help selecting virtual sensors for efficient data collection. We describe utility metrics, tailored specifically for the OpenIoT use cases, indicating the relevant parameters (e.g. location, bandwidth, availability, privacy), and cost and valuation functions (if applicable)

Configurable Distributed Data Management for the Internet of the Things

One of the main challenges in modern Internet of Things (IoT) systems is the efficient collection, routing and management of data streams from heterogeneous sources, including sources with high ingestion rates. Despite the existence of various IoT data streaming frameworks, there is still no easy way for collecting and routing IoT streams in efficient and configurable ways that are easy to be implemented and deployed in realistic environments. In this paper, we introduce a programmable engine for Distributed Data Analytics (DDA), which eases the task of collecting IoT streams from different sources and accordingly, routing them to appropriate consumers. The engine provides also the means for preprocessing and analysis of data streams, which are two of the most important tasks in Big Data analytics applications. At the heart of the engine lies a Domain Specific Language (DSL) that enables the zero-programming definition of data routing and preprocessing tasks. This DSL is outlined in the paper, along with the middleware that supports its runtime execution. As part of the paper, we present the architecture of the engine, as well as the digital models that it uses for modelling data streams in the digital world. We also discuss the validation of the DDA in several data intensive IoT use cases in industrial environments, including use cases in pilot productions lines and in several real-life manufacturing environments. The latter manifest the configurability, programmability and flexibility of the DDA engine, as well as its ability to support practical applications

Defining the stack for service delivery models and interoperability in the internet of things: a practical case with OpenIoT-VDK

This paper introduces the stack for service delivery models and interoperability in the Internet of Things. The main characteristics and functional layers of the IoT stack are described. The applicability of the IoT stack is described based on particular use cases and deployed pilots. The validation of the IoT stack in terms of functionality and adaptation at different IoT particular areas is based on the Virtual Development Kit (VDK) developed and implemented within the framework of the OpenIoT project—OpenIoT project is the awarded Internet of Things open-source rookie of the year by BlackDuck Software Co. (www.github.com/OpenIotOrg). The methods and standards that boosted OpenIoT-VDK implementation are described in this paper. An instance of the OpenIoT-VDK process is described as the practical use case demonstrating being an IoT platform with autonomic behavior. OpenIoT-VDK creates IoT instances, analyzes the IoT stack dependence, and resolves them following interoperability principles. The OpenIoT-VDK instance deploys IoT service delivery models facilitating the validation of use cases by using the OpenIoT platform. As proof of concept, a delivered IoT service using open data from OpenIoT local instantiation is described.This work was supported in part by the ICT OpenIoT Project, which is cofunded by the European Commission through FP7 Program, under Contract FP7-ICT-2011-7-287305-OpenIoT; by the Fed4FIRE Federation for FIRE under Grant FP7-ICT-2011-8-318389; and by the Science Foundation Ireland (SFI) under Grant SFI/12/RC/2289

Dissemination and activity report V1: FIESTA D7.1.1

This document describes the dissemination and communication activities for the FIESTA-IoT project for the period M1 (February 2015) to M12 (January 2015). The dissemination plan is also presented, first describing how promotional material, FIESTA-IoT results, and FIESTA-IoT activities will be used to promote and engage with target communities in order to increase awareness of FIESTA-IoT results, and the FIESTA experimental facility. This document cover the started in M1 dissemination activities but will intensify from M12 onwards in preparation for open calls and engagement with IoT Communities of experimenters and testbeds.The dissemination activities carried out in the first year are described and material generated during the first year is included; these already cover a broad range of activities and communities:• Scientific publications.• Participation (and presentation) at relevant (IoT) events, conferences, summerschools, workshops, meetings.• Demos and exhibitions.• Standards community events.An initial plan for the second year of the project (February 2016 to January 2017) is presented to conclude the report. This outlines potential joint publications for research results, and target events where the FIESTA-IoT facility can be demonstrated, and the upcoming Open Calls can be advertised.Finally, a mapping of the dissemination activities against the objective goals of the project is presented that also serves as self-evaluation for the progress in achievements of the FIESTA-IoT project
