Robustness of Compressed Sensing in Sensor Networks
Abstract
Compressed sensing is a new theory that is based on the fact that many natural
images can be sparsely represented in an orthonormal wavelet basis. This theory holds
valuable implications for wireless sensor networks because power and bandwidth are
limited resources. Applying the theory of compressed sensing to the sensor network
data recovery problem, we describe a measurement scheme by which sensor network
data can be compressively sampled and reconstructed. Then we analyze the robustness
of this scheme to channel noise and fading coefficient estimation error. We demonstrate
empirically that compressed sensing can produce significant gains for sensor network
data recovery in both ideal and noisy environments.
