A wireless Sensor Network that use Image Processing for Vineyard Monitoring

Lloret, Jaime; Bosch Roig, Ignacio; Sendra Compte, Sandra; Serrano Cartagena, Arturo (MDPI, 2011)

The first step to detect when a vineyard has any type of deficiency, pest or disease is to observe its stems, its grapes and/or its leaves. To place a sensor in each leaf of every vineyard is obviously not feasible in terms ...
An adaptive handover prediction scheme for seamless mobility based wireless networks

Sadiq, Ali Safa; Fisal, Norsheila Binti; Ghafoor, Kayhan Zrar; Lloret, Jaime (Hindawi Publishing Corporation, 2014)

We propose an adaptive handover prediction (AHP) scheme for seamless mobility based wireless networks. That is, the AHP scheme incorporates fuzzy logic with AP prediction process in order to lend cognitive capability to ...
Development and assessment of a wireless sensor and actuator network for heating and cooling loads

Molina García, Ángel; Fuentes Moreno, Juan Álvaro; Gómez Lázaro, Emilio; Bonastre Pina, Alberto Miguel; Campelo Rivadulla, José Carlos; Serrano Martín, Juan José (Institute of Electrical and Electronics Engineers (IEEE), 2012-09)

This paper describes a wireless sensor-actuator network to monitor and manage thermostatically controlled loads, mainly heating and cooling loads, which accounts for around 50% of the residential electricity consumption. ...
Diseño e implementación de un sistema de aforo automático destinado a la gestión del tráfico en rotondas e intersecciones con aplicación en proyectos de Ciudades Inteligentes

Kouaou Carretón, Samira (Universitat Politècnica de València, 2021-10-06)

Fiber Wireless Transmission of 8.3-Gb/s/ch QPSK-OFDM Signals in 75-110-GHz Band

Deng, Lei; Beltrán Ramírez, Marta; Pang, Xiaodan; Zhang, Xu; Arlunno, Valeria; Zhao, Ying; Caballero, Antonio; Dogadaev, Anton; Yu, Xianbin; Llorente Sáez, Roberto; Liu, Deming; Monroy, Idelfonso Tafur (Institute of Electrical and Electronics Engineers (IEEE), 2012-03)

[EN] In this letter, we present a scalable high-speed W-band (75-110-GHz) fiber wireless communication system. By using an optical frequency comb generator, three-channel 8.3-Gb/s/ch optical orthogonal frequency-division ...
Flying ad-hoc network application scenarios and mobility models

Bujari, Armir; Tavares de Araujo Cesariny Calafate, Carlos Miguel; Cano, Juan-Carlos; Manzoni, Pietro; Palazzi, Claudio Enrico; Ronzani, Daniele (SAGE Publications, 2017)

[EN] Flying ad-hoc networks are becoming a promising solution for different application scenarios involving unmanned aerial vehicles, like urban surveillance or search and rescue missions. However, such networks present ...
Historical Building Monitoring Using an Energy-Efficient Scalable Wireless Sensor Network Architecture

Capella Hernández, Juan Vicente; Perles Ivars, Ángel Francisco; Bonastre Pina, Alberto Miguel; Serrano Martín, Juan José (MDPI, 2011)

We present a set of novel low power wireless sensor nodes designed for monitoring wooden masterpieces and historical buildings, in order to perform an early detection of pests. Although our previous star-based system ...
