An Efficient Compressed Sensing Transmission Scheme in Wireless Sensor Network
Rongfang Song · Journal of Nanjing University of Posts and Telecommunications · 2012
In traditional wireless sensor network(WSN),data source nodes transmit the original collected data sequence to the data reception center directly for processing.If the data sequence needs to be collected is very long or the number of data source nodes is very large,the data reception center will have a very large amount of data to process.Based on the compressed sensing theory,this paper proposes a novel scheme of data transmission with high efficiency.We use register capacity required for storage and forwarding,and time delay to evaluate the performance of WSN.The simulation results show that compressed sensing can reduce the amount of data while keeping perfect reconstruction of the signal,and then drop the demand to hardware and improve the performance of WSN.
