Power Consumption Analysis of Operating Systems for Wireless Sensor Networks
In this paper four wireless sensor network operating systems are compared in terms of power consumption. The analysis takes into account the most common operating systems-TinyOS v1.0, TinyOS v2.0, Mantis and Contiki-running on Tmote Sky and MICAz devices. With the objective of ensuring a fair evaluation, a benchmark composed of four applications has been developed, covering the most typical tasks that a Wireless Sensor Network performs. The results show the instant and average current consumption of the devices during the execution of these applications. The experimental measurements provide a good insight into the power mode in which the device components are running at every moment, and t…
Gatherer: an environmental monitoring application based on IPv6 using wireless sensor networks
In this paper, we present an environmental monitoring application based on IPv6 using wireless sensor networks. We show the guidelines to connect this network to internet using the 6LowPAN standard with a real prototype in the evolution of the Internet of Things. We assign a unique IPv6 address to the different nodes motes of the network. Gatherer is based on TinyOS using IPv6 and UDP protocols and allows the data gathering of temperature and relative humidity from the different motes, requesting specific data from individual motes when required, increasing the accuracy of the measures. We compare the performance of our IPv6-based proposed application against others and show the benefits of…
Reconstrucción del entorno radio para comunicaciones en agrupaciones de vehículos
Los pelotones de vehículos son grupos de vehículos que viajan juntos, manteniendo una distancia constante entre ellos. Los pelotones suelen necesitar comunicaciones inalámbricas sólidas y fiables para mantener su estructura y realizar maniobras coordinadas. Cuando el pelotón es asistido por la infraestructura a través de una comunicación celular vehículo a todo (V2X), uno de los factores críticos es reducir la latencia de la comunicación. En este trabajo se explora el uso de una técnica de interpolación espacial, concretamente el Kriging Ordinario, como mecanismo para reducir la sobrecarga de señalización en la etapa de adquisición de información del canal, lo que puede repercutir en la prá…
Incorporación de Internet de las Cosas (IoT) en la docencia universitaria en dos etapas: hardware y software
[EN] IoT is a concept referred to a network of common objects interconnected through the Internet. This is one of the main areas with growing interest and also necessary for the Telecommunication and Telematics Engineering students. The main constraints which face the students with IoT are the integration of the hardware as well as the need for management systems to handle the amount of data they generate by specific software. This work shows some experiences done by a group of students in the Telematics Engineering Degree and the Master of Telecommunications.
