    GPS based Bluetooth Broadcasting – Long Range Solution

    Get PDF
    In this paper, GPS based Bluetooth broadcasting for long range is proposed. System model for Long range broadcasting of messages with multiple piconets and dynamically created threshold devices, based on GPS information is presented. Our simulation results have shown that, message can be received by those devices which are out of the initial Bluetooth range in reasonable time. Flooding of multiple messages could be avoided by applying hash function. With this solution, long range data and voice communication could be done with free of cost also can be used for commercial advertising purpose

    Sensor Networks and Their Applications: Investigating the Role of Sensor Web Enablement

    Get PDF
    The Engineering Doctorate (EngD) was conducted in conjunction with BT Research on state-of-the-art Wireless Sensor Network (WSN) projects. The first area of work is a literature review of WSN project applications, some of which the author worked on as a BT Researcher based at the world renowned Adastral Park Research Labs in Suffolk (2004-09). WSN applications are examined within the context of Machine-to-Machine (M2M); Information Networking (IN); Internet/Web of Things (IoT/WoT); smart home and smart devices; BT’s 21st Century Network (21CN); Cloud Computing; and future trends. In addition, this thesis provides an insight into the capabilities of similar external WSN project applications. Under BT’s Sensor Virtualization project, the second area of work focuses on building a Generic Architecture for WSNs with reusable infrastructure and ‘infostructure’ by identifying and trialling suitable components, in order to realise actual business benefits for BT. The third area of work focuses on the Open Geospatial Consortium (OGC) standards and their Sensor Web Enablement (SWE) initiative. The SWE framework was investigated to ascertain its potential as a component of the Generic Architecture. BT’s SAPHE project served as a use case. BT Research’s experiences of taking this traditional (vertical) stove-piped application and creating SWE compliant services are described. The author’s findings were originally presented in a series of publications and have been incorporated into this thesis along with supplementary WSN material from BT Research projects. SWE 2.0 specifications are outlined to highlight key improvements, since work began at BT with SWE 1.0. The fourth area of work focuses on Complex Event Processing (CEP) which was evaluated to ascertain its potential for aggregating and correlating the shared project sensor data (‘infostructure’) harvested and for enabling data fusion for WSNs in diverse domains. Finally, the conclusions and suggestions for further work are provided

    LifeLogging: personal big data

    Get PDF
    We have recently observed a convergence of technologies to foster the emergence of lifelogging as a mainstream activity. Computer storage has become significantly cheaper, and advancements in sensing technology allows for the efficient sensing of personal activities, locations and the environment. This is best seen in the growing popularity of the quantified self movement, in which life activities are tracked using wearable sensors in the hope of better understanding human performance in a variety of tasks. This review aims to provide a comprehensive summary of lifelogging, to cover its research history, current technologies, and applications. Thus far, most of the lifelogging research has focused predominantly on visual lifelogging in order to capture life details of life activities, hence we maintain this focus in this review. However, we also reflect on the challenges lifelogging poses to an information retrieval scientist. This review is a suitable reference for those seeking a information retrieval scientist’s perspective on lifelogging and the quantified self

    An electronic architecture for mediating digital information in a hallway fac̦ade

    Ubiquitous computing requires integration of physical space with digital information. This presents the challenges of integrating electronics, physical space, software and the interaction tools which can effectively communicate with the audience. Many research groups have embraced different techniques depending on location, context, space, and availability of necessary skills to make the world around us as an interface to the digital world. Encouraged by early successes and fostered by project undertaken by tangible visualization group. We introduce an architecture of Blades and Tiles for the development and realization of interactive wall surfaces. It provides an inexpensive, open-ended platform for constructing large-scale tangible and embedded interfaces. In this paper, we propose tiles built using inexpensive pegboards and a gateway for each of these tiles to provide access to digital information. The paper describes the architecture using a corridor fa\c{c}ade application. The corridor fa\c{c}ade uses full-spectrum LEDs, physical labels and stencils, and capacitive touch sensors to provide mediated representation, monitoring and querying of physical and digital content. Example contents include the physical and online status of people and the activity and dynamics of online research content repositories. Several complementary devices such as Microsoft PixelSense and smartdevices can support additional user interaction with the system. This enables interested people in synergistic physical environments to observe, explore, understand, and engage in ongoing activities and relationships. This paper describes the hardware architecture and software libraries employed and how they are used in our research center hallway and academic semester projects
