Powering the Internet of Things with RIOT: Why? How? What is RIOT?
The crucial importance of software platforms was highlighted by recent events
both at the political level (e.g. renewed calls for digital data and operating
system "sovereignty", following E. Snowden's revelations) and at the business
level (e.g. Android generated a new industry worth tens of billions of euros
yearly). In the Internet of Things, which is expected to generate business at
very large scale, but also to threaten even more individual privacy, such
aspects will be exacerbated. The need for an operating system like RIOT stems
from this context, and this short article outlines RIOT's main non-technical
aspects, as well as its key technical characteristics.Comment: 4 page
Design Fiction Diegetic Prototyping: A Research Framework for Visualizing Service Innovations
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.Purpose: This paper presents a design fiction diegetic prototyping methodology and research framework for investigating service innovations that reflect future uses of new and emerging technologies.
Design/methodology/approach: Drawing on speculative fiction, we propose a methodology that positions service innovations within a six-stage research development framework. We begin by reviewing and critiquing designerly approaches that have traditionally been associated with service innovations and futures literature. In presenting our framework, we provide an example of its application to the Internet of Things (IoT), illustrating the central tenets proposed and key issues identified.
Findings: The research framework advances a methodology for visualizing future experiential service innovations, considering how realism may be integrated into a designerly approach.
Research limitations/implications: Design fiction diegetic prototyping enables researchers to express a range of ‘what if’ or ‘what can it be’ research questions within service innovation contexts. However, the process encompasses degrees of subjectivity and relies on knowledge, judgment and projection.
Practical implications: The paper presents an approach to devising future service scenarios incorporating new and emergent technologies in service contexts. The proposed framework may be used as part of a range of research designs, including qualitative, quantitative and mixed method investigations.
Originality: Operationalizing an approach that generates and visualizes service futures from an experiential perspective contributes to the advancement of techniques that enables the exploration of new possibilities for service innovation research
Enabling High-Level Application Development for the Internet of Things
Application development in the Internet of Things (IoT) is challenging
because it involves dealing with a wide range of related issues such as lack of
separation of concerns, and lack of high-level of abstractions to address both
the large scale and heterogeneity. Moreover, stakeholders involved in the
application development have to address issues that can be attributed to
different life-cycles phases. when developing applications. First, the
application logic has to be analyzed and then separated into a set of
distributed tasks for an underlying network. Then, the tasks have to be
implemented for the specific hardware. Apart from handling these issues, they
have to deal with other aspects of life-cycle such as changes in application
requirements and deployed devices. Several approaches have been proposed in the
closely related fields of wireless sensor network, ubiquitous and pervasive
computing, and software engineering in general to address the above challenges.
However, existing approaches only cover limited subsets of the above mentioned
challenges when applied to the IoT. This paper proposes an integrated approach
for addressing the above mentioned challenges. The main contributions of this
paper are: (1) a development methodology that separates IoT application
development into different concerns and provides a conceptual framework to
develop an application, (2) a development framework that implements the
development methodology to support actions of stakeholders. The development
framework provides a set of modeling languages to specify each development
concern and abstracts the scale and heterogeneity related complexity. It
integrates code generation, task-mapping, and linking techniques to provide
automation. Code generation supports the application development phase by
producing a programming framework that allows stakeholders to focus on the
application logic, while our mapping and linking techniques together support
the deployment phase by producing device-specific code to result in a
distributed system collaboratively hosted by individual devices. Our evaluation
based on two realistic scenarios shows that the use of our approach improves
the productivity of stakeholders involved in the application development
What influences the speed of prototyping? An empirical investigation of twenty software startups
It is essential for startups to quickly experiment business ideas by building
tangible prototypes and collecting user feedback on them. As prototyping is an
inevitable part of learning for early stage software startups, how fast
startups can learn depends on how fast they can prototype. Despite of the
importance, there is a lack of research about prototyping in software startups.
In this study, we aimed at understanding what are factors influencing different
types of prototyping activities. We conducted a multiple case study on twenty
European software startups. The results are two folds, firstly we propose a
prototype-centric learning model in early stage software startups. Secondly, we
identify factors occur as barriers but also facilitators for prototyping in
early stage software startups. The factors are grouped into (1) artifacts, (2)
team competence, (3) collaboration, (4) customer and (5) process dimensions. To
speed up a startups progress at the early stage, it is important to incorporate
the learning objective into a well-defined collaborative approach of
prototypingComment: This is the author's version of the work. Copyright owner's version

A BUSINESS MODEL TYPE FOR THE INTERNET OF THINGS
The increasing pervasiveness of digital technologies, often referred to as the Internet of Things (IoT), offers a wealth of new services and business model opportunities across an ecosystem of partners - and so it forces companies to rethink their current business models. To date, literature does yet not provide actionable, field-tested model theories for capturing, visualizing and analyzing firms\u27 business models in digitally intensive business environments. \ \ The present paper (research in progress) therefore addresses the need for a business model type for the Internet of Things, which recognizes the affordances and impacts of digitization in order to allow companies to truly tap into new business model opportunities. We describe the design and evaluation of a type model, which enables researchers and practitioners alike to capture, visualize and analyze firms\u27 current and future business models in IoT in a structured and actionable way. For our study we elected an iterative design science research approach, which prioritizes the utility of prototype artifacts. We feel confident of reaching at an empirically tested business model type, drawn from both Strategic Management and Information Systems research.

Science Hackathons for Cyberphysical System Security Research: Putting CPS testbed platforms to good use
A challenge is to develop cyber-physical system scenarios that reflect the
diversity and complexity of real-life cyber-physical systems in the research
questions that they address. Time-bounded collaborative events, such as
hackathons, jams and sprints, are increasingly used as a means of bringing
groups of individuals together, in order to explore challenges and develop
solutions. This paper describes our experiences, using a science hackathon to
bring individual researchers together, in order to develop a common use-case
implemented on a shared CPS testbed platform that embodies the diversity in
their own security research questions. A qualitative study of the event was
conducted, in order to evaluate the success of the process, with a view to
improving future similar events
Contextual impacts on industrial processes brought by the digital transformation of manufacturing: a systematic review
The digital transformation of manufacturing (a phenomenon also known as "Industry 4.0" or "Smart Manufacturing") is finding a growing interest both at practitioner and academic levels, but is still in its infancy and needs deeper investigation. Even though current and potential advantages of digital manufacturing are remarkable, in terms of improved efficiency, sustainability, customization, and flexibility, only a limited number of companies has already developed ad hoc strategies necessary to achieve a superior performance. Through a systematic review, this study aims at assessing the current state of the art of the academic literature regarding the paradigm shift occurring in the manufacturing settings, in order to provide definitions as well as point out recurring patterns and gaps to be addressed by future research. For the literature search, the most representative keywords, strict criteria, and classification schemes based on authoritative reference studies were used. The final sample of 156 primary publications was analyzed through a systematic coding process to identify theoretical and methodological approaches, together with other significant elements. This analysis allowed a mapping of the literature based on clusters of critical themes to synthesize the developments of different research streams and provide the most representative picture of its current state. Research areas, insights, and gaps resulting from this analysis contributed to create a schematic research agenda, which clearly indicates the space for future evolutions of the state of knowledge in this field
