Abstract-- We present Adaptive Sensing, an energy-efficient
topology configuration method for environment monitoring using
densely deployed wireless sensor networks. Adaptive Sensing puts
redundant nodes into passive mode as auxiliary nodes to be used
later on, thereby extending the system lifetime. Sensor data is col-
lected at powerful macronodes periodically and a low-order model
is fitted to compute a prediction area for each sensor. This predic-
tion area is used to measure the redundancy level of the sensors
covered in it. The redundant nodes are put into passive mode by
macronodes while keeping the distortion in the output low. We
analyze the energy-distortion tradeoff in monitoring applications,
