    Distributed Homology Algorithm to Detect Topological Events Via Wireless Sensor Networks

    Wireless Sensor Networks (WSNs) can span large geographical regions and collaboratively monitor environmental phenomena, for example, forest fires. By designing a WSN to detect changes to such phenomena, current environmental monitoring systems could be supplemented, if not replaced. This research focuses on incremental insertion events, arising from the elevation of...

    Power-Efficient-Coded Architecture for Distributed Wireless Sensing

    Most distributed wireless sensor systems avoid using error correction codes because of the added complexity and power consumption of the decoders. Therefore these uncoded sensor systems are not capable of providing a robust communication link in noisy environments. This leads to a high packet loss, limits the communication range and...

    Signal Detection in Passive Wireless Sensor Networks Based on Back-Propagation Neural Networks

    Passive wireless sensors with no on-board power source, enable a myriad of embedded sensor applications in hard to reach areas, rotating or moving objects and harsh environments. Structural monitoring, weight-limited aerospace vehicles, smart homes and smart grids are some examples in which usage of wireless sensors are ideal. However, power...

    Strategic Web-Service Agreements

    This paper addresses issues of strategy in Web service composition, and inter-site collaboration in general. The results are useful for both human and artificial agents of a site who are responsible for determining Web-service agreements that are most profitable for that site. The authors discuss three specific questions in this...

    Low-Latency Indoor Localization Using Bluetooth Beacons

    Indoor localization refers to the task of determining the location of a traveler in spaces such as large building complexes or airport terminals using coordinates appropriate to those spaces such as floor and room number or airport terminal and gate. Indoor localization using Bluetooth beacons is attractive because of the...

    Game Theoretic Power Allocation in Sparsely Distributed Clusters of Wireless Sensors (GPAS)

    Sparsely distributed clusters of wireless sensors with applications ranging from state-wide wireless bridge monitoring to animal herds tracking have gained recent attention due to their special characteristics and challenging resource allocation problem. A novel optimal power allocation paradigm based on game theory is proposed to minimize the inter and intra-cluster...

    Climate Data Visualization

    This paper describes the motivation for and design of a MATLAB Graphical User Interface (GUI) and the underlying program for generating visualizations of climate data. The program works with data in the netCDF format from the NCEP/NCAR reanalysis project to create the visualizations. The visualizations can be output as AVI...

    High-Resolution Data Visualization

    High-resolution data visualization is useful when wanting to look at data on a larger scale while maintaining finer details. While using a projector helps show information on a larger scale, the pixels are only enlarged and detail is lost due to the inflated pixel size. By using a grid of...
