Nowadays, the vast majority of information monitoring in industrial plants is still carried out by wired technologies, in which the installation and maintenance cost is high. However, in outdoor applications, such as those used in the oil and gas industry, the use of Wireless Sensor Networks (WSN) is increasing due to mobility, reliability, and low cost of the sensor nodes that make up the network. Moreover, this solution reduces the risks of workers in classified areas (regions with high probability of accidents occurrence) to the extent that the equipment maintenance is optimized.  This paper proposes the development of the EEWES, an energy efficient wireless sensor network embedded system, which can be applied on industrial environments. This development approach significantly reduces the energy consumption of the sensor nodes by using a method that alternates sleep periods of the transceiver/sensor set with data transmission/reception periods, which reduces the duty cycle while keeping the desirable parameters of the service quality (QoS). The results presented in this paper will be confirmed by field tests.

Actualmente, la gran mayoría de información de monitoreo en plantas industriales es transmitida a través de tecnologías alámbricas cuyo costo de instalación y mantenimiento es alto. Sin embargo, en aplicaciones outdoor tales como las utilizadas en la industria del petróleo y el gas, el uso de la red de sensores inalámbricos (WSN) ha ido creciendo debido a la movilidad, confiabilidad y bajo costo de sus nodos sensores.  Esta solución reduce los riesgos de los trabajadores en las áreas peligrosas (regiones con alta probabilidad de accidentes) en la medida en que el mantenimiento de los equipos se ha optimizado. El presente artículo propone el desarrollo de EEWES - Sistema Integrado para Red de Sensores Inalámbricos con Eficiencia de Energía, que se puede aplicar en entornos industriales. El consumo de energía de los nodos sensores se reduce significativamente mediante el uso de un método que alterna períodos de apagado de su subsistema de detección y comunicaciones con los períodos de transmisión y recepción de datos, reduciendo el ciclo de trabajo mediante el mantenimiento de los parámetros deseables de calidad de servicio. Los resultados presentados en este trabajo serán confirmados experimentalmente mediante pruebas de campo.
