Integration of autonomous wireless sensor networks in academic school gardens
(MDPI, 2018)
info:eu-repo/semantics/article,
In this work, the combination of capabilities provided by Wireless Sensor Networks (WSN) with parameter observation in a school garden is employed in order to provide an environment for school garden integration as a ...
Design and experimental validation of a LoRaWAN fog computing based architecture for IoT enabled smart campus applications
(MDPI, 2019)
info:eu-repo/semantics/article,
A smart campus is an intelligent infrastructure where smart sensors and actuators collaborate to collect information and interact with the machines, tools, and users of a university campus. As in a smart city, a smart ...
Performance evaluation and interference characterization of wireless sensor networks for complex high-node density scenarios
(MDPI, 2019)
info:eu-repo/semantics/article,
The uncontainable future development of smart regions, as a set of smart cities’ networks assembled, is directly associated with a growing demand of full interactive and connected ubiquitous smart environments. To achieve ...
Impact of body wearable sensor positions on UWB ranging
(IEEE, 2019)
info:eu-repo/semantics/article,
In recent years, Ultrawideband (UWB) has become a very popular technology for time of flight (TOF) based localization and tracking applications but its human body interactions have not been studied yet extensively. Most ...
A radio channel model for D2D communications blocked by single trees in forest environments
(MDPI, 2019)
info:eu-repo/semantics/article,
In this paper we consider the D2D (Device-to-Device) communication taking place between Wireless Sensor Networks (WSN) elements operating in vegetation environments in order to achieve the radio channel characterization ...
Effects of the body wearable sensor position on the UWB localization accuracy
(MDPI, 2019)
info:eu-repo/semantics/article,
Over the years, several Ultrawideband (UWB) localization systems have been proposed and evaluated for accurate estimation of the position for pedestrians. However, most of them are evaluated for a particular wearable sensor ...
Implementation of radiating elements for radiofrequency front-ends by screen-printing techniques for Internet of Things applications
(MDPI, 2019)
info:eu-repo/semantics/article,
The advent of the Internet of Things (IoT) has led to embedding wireless transceivers into a wide range of devices, in order to implement context-aware scenarios, in which a massive amount of transceivers is foreseen. In ...
Deterministic propagation modeling for intelligent vehicle communication in smart cities
(MDPI, 2018)
info:eu-repo/semantics/article,
Vehicular Ad Hoc Networks (VANETs) are envisaged to be a critical building block of Smart Cities and Intelligent Transportation System (ITS) where applications for pollution, congestion reduction, vehicle mobility improvement, ...
Spatial characterization of personal RF-EMF exposure in public transportation buses
(IEEE, 2019)
Artículo / Artikulua,
New services and applications within vehicular environments employ multiple wireless communication systems,
within a Heterogeneous Network framework. In this context, evaluation of electromagnetic field impact is compulsory, ...
FDTD and empirical exploration of human body and UWB radiation interaction on TOF ranging
(IEEE, 2019)
Artículo / Artikulua,
In time-of-flight (TOF)-based human ranging systems, target sensors are often mounted on or close to the human
body, which may raise non-line-of-sight (NLOS) cases and lead
to significant ranging errors depending on the ...
