Middleware Technologies for Cloud of Things - a survey
The next wave of communication and applications rely on the new services
provided by Internet of Things which is becoming an important aspect in human
and machines future. The IoT services are a key solution for providing smart
environments in homes, buildings and cities. In the era of a massive number of
connected things and objects with a high grow rate, several challenges have
been raised such as management, aggregation and storage for big produced data.
In order to tackle some of these issues, cloud computing emerged to IoT as
Cloud of Things (CoT) which provides virtually unlimited cloud services to
enhance the large scale IoT platforms. There are several factors to be
considered in design and implementation of a CoT platform. One of the most
important and challenging problems is the heterogeneity of different objects.
This problem can be addressed by deploying suitable "Middleware". Middleware
sits between things and applications that make a reliable platform for
communication among things with different interfaces, operating systems, and
architectures. The main aim of this paper is to study the middleware
technologies for CoT. Toward this end, we first present the main features and
characteristics of middlewares. Next we study different architecture styles and
service domains. Then we presents several middlewares that are suitable for CoT
based platforms and lastly a list of current challenges and issues in design of
CoT based middlewares is discussed.Comment: http://www.sciencedirect.com/science/article/pii/S2352864817301268,

Blockchain: A Business Model Innovation Analysis
The adoption of blockchain-based technologies by organisations can bring benefits in terms of firms' profitability, productivity and efficiency, making companies rethink their existing business models. However, as the technology is still developing and the research on the implications of the different types of blockchain networks (i.e. public, private, consortium) is scarce, their role in business model innovation requires closer attention. To address this gap, the paper provides a conceptual insight into the role of blockchain technology in companies with different value configurations by examining the technological conditions that can impact business models and probing the role of technology benefits in driving company value. The analysis contributes to the literature by discussing the business implications of innovative technologies and uncovering their positive and negative consequences for the value creation, delivery and capture activities. Such analysis sheds light on the functions of blockchains that have a differentiating impact on business processes. Also, the paper puts forward managerial implications by discussing the paths of business model innovation using blockchain technologies

Liquid FM: Recommending Music through Viscous Democracy
Most modern recommendation systems use the approach of collaborative
filtering: users that are believed to behave alike are used to produce
recommendations. In this work we describe an application (Liquid FM) taking a
completely different approach. Liquid FM is a music recommendation system that
makes the user responsible for the recommended items. Suggestions are the
result of a voting scheme, employing the idea of viscous democracy. Liquid FM
can also be thought of as the first testbed for this voting system. In this
paper we outline the design and architecture of the application, both from the
theoretical and from the implementation viewpoints
Safety and Security oriented design for reliable Industrial IoT applications based on WSNs
[EN] Internet of Things based technologies are enabling the digital transformation in many sectors. However, in order to use this type of solutions, such as wireless sensor networks, in scenarios like transport, industry or smart cities, the deployed networks must meet sensible safety and security requirements. This article describes a Wireless Sensor Network design that applies multi-layered mechanisms and tools to ensure security, safety and reliability while maintaining usability in Rail and Industrial IoT scenarios. The proposed solution provides guidelines for choosing the best implementations given usual restrictions, offering a modular stack so it can be combined with other solutions.This work has been supported by the SCOTT project (Secure
COnnected Trustable Things) (www.scottproject.eu), which has
