    In the last years, wireless sensor networks (WSNs) are acquiring more importance as a promising technology based on tiny devices called sensor nodes or motes able to monitor a wide range of physical phenomenon through sensors. Numerous branches of science are being benefited. The intrinsic ubiquity of sensor nodes and the absence of network infrastructure make possible their deployment in hostile or, up to now, unknown environments which have been typically unaccessible for humans such as volcanos or glaciers, providing precise and up-to-date data. As potential applications continue arising, both new technical and conceptual challenges appear. The severe hardware restrictions of sensor nodes in relation to computation, communication and specifically, energy, have posed new and exciting requirements. In particular, research is moving towards heterogeneous networks that will contain different devices running custom WSN operating systems. Operating systems specifically designed for sensor nodes are intended to efficiently manage the hardware resources and facilitate the programming. Nevertheless, they often lack the generality and the high-level abstractions expected at this abstraction layer. Consequently, they do not completely hide either the underlying platform or its execution model, making the applications programming close to operating system and thus reducing the portability. This thesis focuses on the portability of applications in heterogeneous wireless sensor networks. To contribute to this important challenge the thesis proposes a generic software architecture based on sensor node, which supports the process of applications development by homogenizing and facilitating the access to different WSN operating systems. Specifically, the next main objectives have been established. * Designing and implementing a generic sensor node-centric architecture distinguishing clearly the different abstraction levels in a sensor node. The architecture should be flexible enough in order to incorporate high-level abstractions which facilitate the the programming. * As part of the architecture, constructing an intermediate layer between applications and sensor node operating system. This layer is intended to abstract away the operating system by demultiplexing a set of homogeneous services and mapping them into operating system-specific requests. To achieve this, programming language extensions have to be also specified on top of the architecture, in order to write portable applications. In this way, platform-specific code can be generated from these high-level applications for di erent sensor node platforms. In this way, architecture deals with the problem of heterogeneity and portability. * Evaluating the feasibility of incorporating the abstractions above mentioned within the development process in terms of portability, efficiency and productivity. In this environment the footprint is a specially critical issue, due to the hardware limitations. In fact, an excessive overhead of applications size could make prohibitive the proposed solution. The thesis presents a generic software architecture for portable applications in heterogeneous wireless sensor networks. The proposed solution and its evaluation is described in this document. Theoretical and practical contributions of this thesis and the main future research directions are also presented.-------------------------------------------------------------------------------------------------------------------------En los últimos años, las redes de sensores inalámbricas han adquirido cada vez mayor protagonismo y se han erigido como una prometedora tecnología basada en dispositivos pequeños denominados nodos sensores o motes, que son capaces de monitorizar fenómenos físicos a través de diferentes sensores. Un gran número de diferentes ramas de las ciencias podrían verse beneficiadas. La naturaleza ubicua de los nodos además de la ausencia de una infraestructura de red, hacen posible la instalación de estas redes en terrenos inhóspitos y típicamente inaccesibles para los seres humanos, como por ejemplo glaciares o volcanes, para proporcionar un conocimiento preciso y actualizado. A medida que continúan apareciendo diferentes aplicaciones potenciales, surgen nuevos retos tanto técnicos como conceptuales. Las restricciones severas de los recursos en términos de cómputo, comunicación y, sobre todo, energía, plantean nuevos requerimientos. En particular, la investigación tiende a crear redes heterogéneas que incluyen diferentes dispositivos de hardware e integran sistemas operativos desarrollados ad-hoc. Los sistemas operativos específicamente diseñados para nodos sensores han sido concebidos para gestionar eficientemente sus recursos de hardware y facilitar la programación. Sin embargo, a menudo carecen de la generalidad y de las abstracciones de alto nivel esperadas en esta capa de abstracción. Por tanto, los sistemas operativos no enmascaran completamente su modelo de ejecución ni la plataforma subyacente, convirtiendo la programación de aplicaciones en fuertemente acoplada al sistema operativo y, consecuentemente, reduciendo la portabilidad. Esta tesis se centra en la portabilidad de aplicaciones en redes de sensores inalámbricas heterogéneas. Con el objeto de contribuir a este relevante ámbito de estudio, la tesis propone una arquitectura de software genérica basada en nodo sensor, la cual soporta el proceso de desarrollo de aplicaciones homogeneizando y facilitando el acceso a diferentes sistemas operativos de nodos sensores. Específicamente, se han establecido los siguientes objetivos principales: * Diseñar e implementar una arquitectura genérica de nodo sensor distinguiendo con claridad los diferentes niveles de abstracción del nodo sensor. La arquitectura propuesta debería ser flexible para poder incorporar nuevas abstracciones de alto nivel que faciliten la programación de las aplicaciones. * Como parte de la arquitectura, deberá construirse una capa de abstracción localizada entre las aplicaciones y el sistema operativo. Su objetivo es abstraer el sistema operativo subyacente mediante un conjunto de servicios homogéneos que puedan ser mapeados en servicios específicos del sistema operativo. Para ello se deberá especificar en la capa superior de la arquitectura el conjunto de extensiones del lenguaje de programación que permitan escribir aplicaciones portables. Consecuentemente, el código específico de la plataforma puede ser generado a partir de las aplicaciones de alto nivel para diferentes plataformas de nodos sensores. De esta manera, la arquitectura trata los problemas de portabilidad y heterogeneidad en la construcción de aplicaciones. * Evaluar la factibilidad de incorporar las abstracciones previamente mencionadas para ser usadas dentro del proceso de desarrollo de aplicaciones, en términos de portabilidad, eficiencia y productividad. En el entorno de las redes de sensores, el consumo eficiente de los recursos de hardware es un aspecto crítico debido al presupuesto limitado del hardware. De hecho, una sobrecarga excesiva haría prohibitiva e inviable la propuesta. Esta tesis describe una arquitectura de software genérica para aplicaciones portables en redes de sensores inalámbricas heterogéneas. La solución propuesta y su evaluación se presentan en este documento. Las contribuciones teóricas y prácticas de esta tesis serán analizadas, así como las líneas futuras de investigación que derivan de este trabajo

    Mobilizing the Past for a Digital Future : The Potential of Digital Archaeology

    Get PDF
    Mobilizing the Past is a collection of 20 articles that explore the use and impact of mobile digital technology in archaeological field practice. The detailed case studies present in this volume range from drones in the Andes to iPads at Pompeii, digital workflows in the American Southwest, and examples of how bespoke, DIY, and commercial software provide solutions and craft novel challenges for field archaeologists. The range of projects and contexts ensures that Mobilizing the Past for a Digital Future is far more than a state-of-the-field manual or technical handbook. Instead, the contributors embrace the growing spirit of critique present in digital archaeology. This critical edge, backed by real projects, systems, and experiences, gives the book lasting value as both a glimpse into present practices as well as the anxieties and enthusiasm associated with the most recent generation of mobile digital tools. This book emerged from a workshop funded by the National Endowment for the Humanities held in 2015 at Wentworth Institute of Technology in Boston. The workshop brought together over 20 leading practitioners of digital archaeology in the U.S. for a weekend of conversation. The papers in this volume reflect the discussions at this workshop with significant additional content. Starting with an expansive introduction and concluding with a series of reflective papers, this volume illustrates how tablets, connectivity, sophisticated software, and powerful computers have transformed field practices and offer potential for a radically transformed discipline.https://dc.uwm.edu/arthist_mobilizingthepast/1000/thumbnail.jp
