“…Services dynamically discover resource directories using DNS Service Discovery (DNS-SD) [24] and then register their endpoints in the directory to allow these to be discovered by other users. CoRE resource directories support attribute-based queries; however, Constrained Application Protocol (CoAP)-based [25] approaches do not provide unambiguous service specifications or include mechanisms to describe service context [26]. The W3C defines the WoT Discovery process [27], with an optional Thing Directory to support service registration which enables querying for services.…”

The Internet of Things (IoT) consists of millions of devices deployed over hundreds of thousands of different networks, providing an ever-expanding resource to improve our understanding of and interactions with the physical world. Global service discovery is key to realizing the opportunities of the IoT, spanning disparate networks and technologies to enable the sharing, discovery, and utilisation of services and data outside of the context in which they are deployed. In this paper, we present Decentralised Service Registries (DSRs), a novel trustworthy decentralised approach to global IoT service discovery and interaction, building on DSF-IoT to allow users to simply create and share public and private service registries, to register and query for relevant services, and to access both current and historical data published by the services they discover. In DSR, services are registered and discovered using signed objects that are cryptographically associated with the registry service, linked into a signature chain, and stored and queried for using a novel verifiable DHT overlay. In contrast to existing centralised and decentralised approaches, DSRs decouple registries from supporting infrastructure, provide privacy and multi-tenancy, and support the verification of registry entries and history, service information, and published data to mitigate risks of service impersonation or the alteration of data. This decentralised approach is demonstrated through the creation and use of a DSR to register and search for real-world IoT devices and their data as well as qualified using a scalable cluster-based testbench for the high-fidelity emulation of peer-to-peer applications. DSRs are evaluated against existing approaches, demonstrating the novelty and utility of DSR to address key IoT challenges and enable the sharing, discovery, and use of IoT services.

“…Context-aware discovery services can be used to minimize the overload of control operations in IoT applications. The work in (Barreto et al 2017) presents a Constrained Application Protoco (CoAP) extension to support the context-aware discovery of smart objects. This extension matches interest and context information with the smart objects state data to retrieve the most relevant artifacts.…”

Software Engineering principles and practices promote the reuse of existing elements to maximize the performance of development and maintenance processes. The core concepts of reusability are aligned with the FAIR (Findability, Accessibility, Interoperability, and Reusability) principles. From our perspective, FAIR principles are not only related to data in a software system, because there are other resources and parts of a system that are related to data indirectly or require data schemas and models for their description and management. Examples of these resources are services, business logic processes, contracts, security policies, architectures, components, deployment resources, execution rules, or interaction alternatives, among other possible examples. Actually, any resource in a system may need to be discovered either internally by a subprocess, or externally by any client that might be interested in finding, accessing, interoperating, or reusing it. This paper addresses a systematic literature review to analyze the current principles, paradigms, and technologies that can be applied to enable discovering and reusing mechanisms in modern software systems, and how traditional and outdated approaches have been adapted to support present issues. From this analysis, we outlined the challenges and open research lines that can be addressed to achieve a suitable reuse strategy.

“…It is noteworthy that this paper ties in three coordinated research efforts within the Engineering of Context-aware software systems. With CoAP-CTX [5], the authors aim to facilitate service discovery in IoT self-adaptive systems. Next, with SUCCEEd [6], researchers aim to support self-adaptation by providing a framework that supports the specification of strategies and rules.…”
