“…Heterogeneous sensor data (e.g., soil moisture and temperature and humidity of some server control rooms) gathered by heterogeneous wireless sensor networks (e.g., DASH7 [70,71], LoRa (https://www.semtech.com/technology/lora/what-is-lora) and 6LowPan (https://tools.ietf.org/ html/rfc6282)) are sent over MQTT along with the temperatures of CPUs and hard disks of a set of servers. The application is an example of how raw data (i.e., the topic-value pairs provided by an MQTT broker) can be mapped into RDF triples.…”

This paper presents a decentralized Web-based architecture designed to support the development of distributed, dynamic, context-aware and interoperable services and applications. The architecture enables the detection and notification of changes over the Web of Data by means of a content-based publish-subscribe mechanism where the W3C SPARQL 1.1 Update and Query languages are fully supported and used respectively by publishers and subscribers. The architecture is built on top of the W3C SPARQL 1.1 Protocol and introduces the SPARQL 1.1 Secure Event protocol and the SPARQL 1.1 Subscribe Language as a means for conveying and expressing subscription requests and notifications. The reference implementation of the architecture offers to developers a design pattern for a modular, scalable and effective application development.

“…One of the main challenges in this field consists of the adaptation of Semantic Web technologies in order to make them comply with the requirements of highly constrained IoT scenarios, such as those of the Internet of Musical Things. Among the examples of technologies exploiting semantics in the IoT, it is worth mentioning the works reported in [24] and [25], where authors rely on a semantic middleware providing publish-subscribe functionalities on top of an RDF knowledge base [26] in two different IoT scenarios: electro-mobility and home automation. In the music domain, several applications of the Semantic Web were reported in [17].…”

The Internet of Musical Things is an emerging research area that relates to the network of Musical Things, which are computing devices embedded in physical objects dedicated to the production and/or reception of musical content. In this paper we propose a semantically-enriched Internet of Musical Things architecture which relies on a semantic audio server and edge computing techniques. Specifically, a SPARQL Event Processing Architecture is employed as an interoperability enabler allowing multiple heterogeneous Musical Things to cooperate, relying on a music-related ontology. We technically validate our architecture by implementing an ecosystem around it, where five Musical Thing prototypes communicate between each other.

T his wor k discusses the impact of W ake-Up Radio (W uR) technology to extend the battery life on sensor and actuator nodes in a smart home scenario. T he focus is on nodes that harvest energy from light or a temperature gradient and implement D ASH7, an open-source low-power protocol supporting both query-response and beaconing communication models. A prototype W uR is used, with a quiescent cur rent less than 1 µ A and a sensitivity of-38 dBm compatible with indoor applications. E xperimental data show that integrating W uR is not convenient in nodes that need to send a message to the networ k coordinator periodically, e.g. sensor nodes implementing beaconing communication models. O n the contrary, in request-response mode, integrating the W uR, the average actuator cur rent consumption reduces from 35 µ A down to 6 µ A during a reference period where no data or commands are exchanged between the networ k coordinator and the node. T hanks to the W uR, we find that an average light intensity of 150 lux throughout daytime and less than 14 min of a temperature gradient of 10°C between the hot and cold side of a thermoelectric generator are sufficient to turn the actuator nodes for water flooding and smart heating control into an energetically autonomous mode.
