Scale Wireless Sensor Network with Compressed Sensing

Large
-
scale wireless sensor networks (WSNs) consist of a huge number of wireless transceivers, each
with sensing, processing, communication and power supply units to monitor the real
-
world environment
information: i.e., perform measurements such as pressur
e, temperature, position, flow, vibration, force,
humidity, pollutants and biomedical signals like heart
-
rate and blood pressure.
The ideal WSNs are
designed to consume very limited power and are capable of fast data acquisition and multiple
measurements.


Compressive sensing (CS) is an emerging signal acquisition technique that recovers a sparse signal from
few linear measurements. Due to its popularity, CS is currently applied in many areas such as coding,
signal processing and wireless sensor networks [
2]. In this paper, we present a new CS framework for
wireless sensor networks. We consider a sensor network consisting of S sensors connected to a
centralized fusion center. Each sensor measures a desired sparse signal and then compresses the sensed
signal

using a sensing matrix. The compressed measurements from different sensors are sent to the fusion
center for joint recovery of the sparse signals. Thus, we have to consider a wireless sensor network having
S

number of sensors deployed at random locations.

Let s denote a
K
-
sparse signal of length
N

(
K

<<
N
).

Therefore, we have to compress the sensed measurements from N to almost K values only.
