Hybrid computational techniques: electromagnetic propagation analysis in complex indoor environments
(IEEE, 2019)
info:eu-repo/semantics/article,
In this article, we compare deterministic methodologies for characterizing channel behavior in heterogeneous and composite scenarios. These techniques include one that combines a 3D ray launching (RL) approach based on ...
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 ...
Deterministic and empirical approach for millimeter-wave complex outdoor smart parking solution deployments
(MDPI, 2021)
info:eu-repo/semantics/article,
The characterization of different vegetation/vehicle densities and their corresponding effects on large-scale channel parameters such as path loss can provide important information during the deployment of wireless ...
Basketball player on-body biophysical and environmental parameter monitoring based on wireless sensor network integration
(IEEE, 2021)
Artículo / Artikulua,
Sport activities have benefited in recent years from the progressive adoption of different technological assets in order to improve individual as well as group training, collect different statistics or enhance the spectator ...
Design and empirical validation of a LoRaWAN IoT Smart Irrigation System
(MDPI, 2020)
Artículo / Artikulua,
In some parts of the world, climate change has led to periods of drought that require managing efficiently the scarce water and energy resources. This paper proposes an IoT smart irrigation system specifically designed for ...
Fifth-generation (5G) mmwave spatial channel characterization for urban environments’ system analysis
(MDPI, 2020)
info:eu-repo/semantics/article,
In this work, the channel characterization in terms of large-scale propagation, small-scale propagation, statistical and interference analysis of Fifth-Generation (5G) Millimeter Wave (mmWave) bands for wireless networks ...
A 3D ray launching time-frequency channel modeling approach for UWB ranging applications
(IEEE, 2020)
info:eu-repo/semantics/article,
Ultrawideband (UWB) has the ability to achieve decimetre level of ranging accuracy, hence, its wider usage nowadays in the field of positioning. In spite of the attractiveness of UWB, its performance is strongly dependent ...
Building decentralized fog computing-based smart parking systems: from deterministic propagation modeling to practical deployment
(IEEE, 2020)
info:eu-repo/semantics/article,
The traditional process of finding a vacant parking slot is often inefficient: it increases driving time, traffic congestion, fuel consumption and exhaust emissions. To address such problems, smart parking systems have ...
