Node in wireless sensor networks is limited by volume
power
cost
etc
so that energy and lifetime of system are limited. Propose an optimal method based on compressed sensing for energy-saving of wireless sensor networks( WSNs)
combining chain topology network model
propose energy-saving network data transmission model based on compressed sensing theory. Advantage of compressed sensing method in energy-saving is verified by theoretical analysis and comparison
and then simulate on the basis of energy consumption model of the network. Simulation results show that the compressed sensing method effectively reduces network energy consumption.
