Billions of devices are interacting in a growing global network, currently designated as the Internet of Things (IoT). In this scenario, embedded computers with sensors and actuators are widespread in all sorts of smart things, transforming the way we live. The complexity produced by the enormous amount of devices expected in the future IoT leads t...

We present a low-overhead mechanism for self-sovereign identification and communication of IoT agents in constrained networks. Our main contribution is to enable native use of Decentralized Identifiers (DIDs) and DID-based secure communication on constrained networks, whereas previous works either did not consider the issue or relied on proxy-based...

The Internet of Things (IoT) leverages added valued services by the wide spread of connected smart devices. The Swarm Computing paradigm considers a single abstraction layer that connects all kinds of devices globally, from sensors to super computers. In this context, the Low-Power Wide-Area Network (LPWAN) emerges, spreading out connection to the...

While Attribute-Based Access Control (ABAC) is a promising technique to govern interactions in the Internet of Things (IoT), most existing ABAC models are designed to run on remote servers or gateway devices. This scenario is misaligned with recent trends towards IoT decentralization, such as the Swarm, which expects devices to autonomously share r...

A Internet das Coisas é uma rede de objetos físicos que incorporam computação embarcada, sensores, atuadores e conexão com a Internet; tornando-os capazes de coletar, processar e transmitir dados. Desta forma, objetos passivos, passam a se comportar como objetos inteligentes e conectados, tornando possível incorporar inteligência artificial, cripto...

This paper analyses the concept of Self-Sovereign Identity (SSI), an emerging approach for establishing digital identity, in the context of the Internet of Things (IoT). We contrast existing approaches for identity on the Internet, such as cloud-based accounts and digital certificates, with SSI standards such as Decentralized Identifiers (DIDs) and...

Given the large amount of devices in the Internet of Things (IoT), a major challenge is to efficiently find services that meet specific requirements. The proliferation of standards and protocols precludes the existence of a common nomenclature to describe IoT devices, and hence difficults device interoperability. In previous work we had proposed th...

The Internet of Things is steadily growing and migrating to decentralized architectures. In this context the Swarm approach, based on organic, edge-centric IoT networks, proposes one step further towards cooperation among devices, through the creation of a communication mediator called Swarm Broker. An important aspect in creating a cooperation net...

The Internet of Things is revolutionizing society by enabling everyday life objects with processing and communication. The Swarm is an edge-centric IoT approach in which independent, cross-niche, and heterogeneous devices can cooperate with each other to execute tasks synergistically. Access Control is indispensable for the Swarm, as it ensures con...

Swarm vision, consists in an organic ecosystem of heterogeneous devices that communicate and collaborate to achieve complex results. In previous work, we have proposed an architecture to implement this vision based on web technologies. In this paper, we propose a framework that makes the creation of Swarm-ready servients (devices that acts both...

According to industry predictions, by 2020 there will be a plethora of heterogeneous devices connected in the so-called Internet of Things (IoT). There are still many open problems in the field and this article represents the beginning of a research on the suitability of a functional language, Elixir, for building IoT software. Elixir runs on the E...
