Scholarcy highlights

  • A sensor network is a large ad hoc network of densely distributed sensors that are equipped with low power wireless transceivers
  • Such networks can be applied for cooperative signal detection, monitoring, and tracking, and are especially useful for applications in remote or hazardous locations
  • This paper addresses the problem of location discovery at the sensor nodes, which is one of the central design challenges in sensor networks
  • We present a new method by which a sensor node can determine its location by listening to wireless transmissions from three or more fixed beacon nodes
  • The proposed method is based on an angle-of-arrival estimation technique that does not increase the complexity or cost of construction of the sensor nodes
  • The process may takea few minutes but once it finishes a file will be downloaded on your browser soplease do not close the new tab
