G-Sense: a scalable architecture for global sensing and monitoring

The pervasiveness of cellular phones combined with Internet connectivity, GPS embedded chips, location information, and integrated sensors provide an excellent platform to collect data about the individual and its surrounding environment. As a result, new applications have recently appeared to address large-scale societal problems as well as improve the quality of life of the individual. However, these new applications, recently called location-based services, participatory sensing, and human-centric sensing, bring many new challenges, one of them being the management of the huge amount of traffic (data) they generate. This article presents G-Sense, for Global-Sense, an architecture that integrates mobile and static wireless sensor networks in support of location-based services, participatory sensing, and human-centric sensing applications. G-Sense includes specific mechanisms to control the amount of data generated by these applications while meeting the application requirements. Furthermore, it creates a network of servers organized in a peer-to-peer architecture to address scalability and reliability issues. An example prototype application is presented along with some basic results and open research issues

Propiedades de Calidad de Servicio en el Descubrimiento de Recursos Grid

Uno de los problemas abiertos en el contexto de las Arquitecturas Orientadas a Servicios es del descubrimiento de recursos y/o servicios adecuados para llevar a cabo una tarea determinada. Los proveedores de información Grid básicamente ofrecen información funcional sobre los recursos Grid que monitorizan, por lo que los modelos de información Grid básicamente representan esta información sintáctica, y los consumidores de información Grid usan normalmente dichas propiedades funcionales para seleccionar recursos. En la práctica, muchos trabajos se reinician debido a fallos en los recursos, aunque existen iniciativas que tratan de usar técnicas aisladas para manejar algunas propiedades de calidad de servicio. En el presente artículo se propone un nuevo enfoque para modelar recursos Grid junto con propiedades de calidad de servicio. Por un lado, este modelo está basado en una ontología desarrollada para integrar los modelos existentes tanto a nivel de representación de información Grid como de calidad de servicio en general. Por otro lado, también propone la creación de un sistema de medida - actualmente en desarrollo - para algunas propiedades de calidad de servicio (disponibilidad, rendimiento y fiabilidad)

The effects of lightning-produced NO_x and its vertical distribution on atmospheric chemistry: sensitivity simulations with MATCH-MPIC

The impact of different assumptions concerning the source magnitude as well as the vertical placement of lightning-produced nitrogen oxides is studied using the global chemistry transport model MATCH-MPIC. The responses of NO_x, O₃, OH, HNO₃ and peroxyacetyl-nitrate (PAN) are investigated. A marked sensitivity to both parameters is found. NO_x burdens globally can be enhanced by up to 100% depending on the vertical placement and source magnitude strength. In all cases, the largest enhancements occur in the tropical upper troposphere, where lifetimes of most trace gases are longer and where they thus become more susceptible to long-range transport by large-scale circulation patterns. Comparison with observations indicate that 0 and 20 Tg(N)/yr production rates of NO_x from lightning are too low and too high, respectively. However, no single intermediate production rate or vertical distribution can be singled out as best fitting the observations, due to the large scatter in the datasets. This underscores the need for further measurement campaigns in key regions, such as the tropical continents
