  • Distributed alternating localization-triangulation of camera networks 

    Mantzel, William E. (2005)
    Localization, estimating the positions and orientations of a set of camera nodes, is a critical first step in camera-based sensor network applications such as geometric estimation and scene reconstruction. We propose a ...
  • Distributed Camera Network Localization 

    Mantzel, William; Choi, Hyeokho; Baraniuk, Richard G. (2004-11-01)
    Localization, estimating the positions and orientations of a set of cameras, is a critical first step in camera-based sensor network applications such as geometric estimation, scene reconstruction, and motion tracking. We ...
  • Distributed Compressed Sensing of Jointly Sparse Signals 

    Sarvotham, Shriram; Baron, Dror; Wakin, Michael; Duarte, Marco F.; Baraniuk, Richard G. (2005-11-01)
    Compressed sensing is an emerging field based on the revelation that a small collection of linear projections of a sparse signal contains enough information for reconstruction. In this paper we expand our theory for ...
  • Distributed Cooperative Communications in Wireless Networks 

    Khojastepour, Mohammad (2005-01-01)
    The primary challenge in communication over wireless networks, unlike wireline networks, is the existence of interference and channel variations (fading). Having more users at higher data rates means that current ...
  • Distributed cooperative communications in wireless networks 

    Khojastepour, Mohammad Ali (2004)
    The primary challenge in wireless networks, unlike wireline networks, is the existence of interference and channel variations (fading). Having more users at higher data rates means that current point-to-point networks will ...
  • Distributed Decoding in Cooperative Communications 

    Karkooti, Marjan; Cavallaro, Joseph R. (2007-11-01)
    In this paper, we present a novel relaying strategy called distributed and partial decoding. This strategy can be viewed as a variation of the decode and forward with the difference that the relay partially decodes the ...
  • Distributed Image Compression for Sensor Networks using Correspondence Analysis and Super-Resolution 

    Wagner, Raymond; Nowak, Robert David; Baraniuk, Richard G. (2003-09-01)
    We outline a distributed coding technique for images captured from sensors with overlapping fields of view in a sensor network. First, images from correlated views are roughly registered (relative to a sensor of primary ...
  • Distributed Image Compression in Camera Networks 

    Wagner, Raymond (2004-05-01)
    Dense networks of wireless, battery-powered sensors are now feasible thanks to recent hardware advances, but key issues such as power consumption plague widespread deployment. Fortunately, in a dense network of sensors, ...
  • Distributed image compression in camera networks 

    Wagner, Raymond S. (2004)
    Dense networks of wireless, battery-powered sensors are now feasible thanks to recent hardware advances, but key issues such as power consumption plague widespread deployment. Fortunately, in a dense network of sensors, ...
  • Distributed Low-Complexity Maximum-Throughput Scheduling for Wireless Backhaul Networks 

    Kabbani, Abdul; Salonidis, Theodoros; Knightly, Edward (2006-08-01)
    We introduce a low-complexity distributed slotted MAC protocol that can support all feasible arrival rates in a wireless backhaul network (WBN). For arbitrary wireless networks, such a maximum throughput protocol has been ...
  • Distributed multi-scale data processing for sensor networks 

    Wagner, Raymond S. (2007)
    Wireless sensor networks provide a challenging application area for signal processing. Sensor networks are collections of small, battery-operated devices called sensor nodes, each of which is capable of sensing data, ...
  • Distributed Multiscale Data Analysis and Processing for Sensor Networks 

    Wagner, Raymond; Sarvotham, Shriram; Choi, Hyeokho; Baraniuk, Richard G. (2005-02-01)
    While multiresolution data analysis, processing, and compression hold considerable promise for sensor network applications, progress has been confounded by two factors. First, typical sensor data are irregularly spaced, ...
  • Distributed partial decoding in cooperative communication systems 

    Karkooti, Marjan (2009)
    Increasing demand for wireless services is putting major pressure on network resources, which demands a new paradigm with a more efficient design. Recently, cooperative communications has emerged as a viable option for ...
  • Distributed Protocols for Signal-Scale Cooperation 

    Hunter, Christopher R. (2012)
    Signal-scale cooperation is a class of techniques designed to harness the same gains offered by multi-antenna communication in scenarios where devices are too small to contain an array of antennas. While the potential ...
  • Distributed redundant representations in man-made and biological sensing systems 

    Rozell, Christopher John (2007)
    The ability of a man-made or biological system to understand its environment is limited by the methods used to process sensory information. In particular, the data representation is often a critical component of such ...
  • Distributed scheduling and multi-channel opportunistic media access for ad hoc networks 

    Kanodia, Vikram (2004)
    Current wireless ad hoc networks suffer from two main performance limitations. First, current ad hoc networks do not efficiently utilize the scarce and dynamic wireless spectrum. As a result, the goodput of current ad hoc ...
