Mitigando Efectos Adversos de Interrupciones del Servicio de Video-vigilancia del Hogar en Clientes WiFi inalámbricos

[ES] Actualmente los sistemas de videovigilancia en el Hogar se pueden combinar con sensores para formar un sistema de muy bajo coste y fácil manejo por parte del usuario final. Un componente importante en este sistema es el servidor de video streaming en tiempo real a clientes Web que usan Wireless Fidelity. El servidor se puede instalar en open hardware como el Raspberry Pi y se puede ayudar de sensores arduino para detectar alarmas de intrusión o condiciones domóticas adversas en el Hogar. Sin embargo, el Wireless Fidelity tiene conocidos problemas que provoca interrupciones esporádicas e impredecibles del servicio de video y de poca duración que provocan la pérdida de frames de video clave para observar el estado del hogar en un momento dado, mientras el cliente se mueve (después de recibir una alarma). Mitigar los efectos adversos de estas interrupciones es una tarea complicada que hemos trabajado durante años. La novedad es que ahora construimos u sistema de open hardware embebida y de bajo coste (con utilidad práctica a los ciudadanos), y software libre íntegramente basado en servicios Web que es interoperable y basado en ontologías (para incluir decisiones sofisticadas, smart, de reconectar el servicio interrumpido). El elevado valor de parámetros de calidad de experiencia de usuario avalan los buenos resutlados alcanzados.This work has been funded by the Spanish Ministry of Economy and Competitiveness/FEDER under project TEC2015-67387- C4-4-R.

Birds, Lower Sangay National Park, Morona-Santiago, Ecuador

Sangay National Park is located at the mid-eastern Andean foothills of the Cordillera Oriental of Ecuador. We present a preliminary avifauna inventory corresponding to the lower zone of the Sangay National Park (SNP). One-hundred and twenty-seven bird species belonging to 39 families were recorded, including noteworthy records that represent range extensions for four species, Phaetornis hispidus (Gould 1846) (White-bearded Hermit), Ramphastos ambiguus Swainson 1823 (Black-mandibled Toucan), Phylloscartes orbitalis (Cabanis 1873) (Spectacled Bristle Tyrant), and Microcerculus bambla (Boddaert 1783) (Wing-banded Wren). We also obtained information on threatened species such as Aburria aburri (Lesson 1828) (Wattled Guan), Phlogophilus hemileucurus Gould 1860 (Ecuadorian Piedtail), and Dendroica cerulea (Wilson 1810) (Cerulean Warbler) and reproductive data on one species, Patagioenas speciosa (Gmelin 1789) (Scaled Pigeon). To our knowledge this is a first ornithological survey carried out at this specific site of the SNP

Low Cost Efficient Deliverying Video Surveillance Service to Moving Guard for Smart Home

Low-cost video surveillance systems are attractive for Smart Home applications (especially in emerging economies). Those systems use the flexibility of the Internet of Things to operate the video camera only when an intrusion is detected. We are the only ones that focus on the design of protocols based on intelligent agents to communicate the video of an intrusion in real time to the guards by wireless or mobile networks. The goal is to communicate, in real time, the video to the guards who can be moving towards the smart home. However, this communication suffers from sporadic disruptions that difficults the control and drastically reduces user satisfaction and operativity of the system. In a novel way, we have designed a generic software architecture based on design patterns that can be adapted to any hardware in a simple way. The implanted hardware is of very low economic cost; the software frameworks are free. In the experimental tests we have shown that it is possible to communicate to the moving guard, intrusion notifications (by e-mail and by instant messaging), and the first video frames in less than 20 s. In addition, we automatically recovered the frames of video lost in the disruptions in a transparent way to the user, we supported vertical handover processes and we could save energy of the smartphone's battery. However, the most important thing was that the high satisfaction of the people who have used the system
