摘要：传统的无线传感网技术中，数据源节点将采集到的原始数据序列直接传送给中间转发
节点进行处理，因此当需采集的数据序列很长或者数据源节点的数目很多时中间转发节点需
处理的数据量非常大。为此，基于近年来发展迅速的压缩感知理论，本文将压缩感知技术应
用于无线传感网，提出一种新型高效的数据采集传输方案。采用系统所需存储转发寄存器的
容量、节点耗能、时延来衡量无线传感网的网络性能。仿真结果表明，压缩感知理论可在近
乎完美地重建信号的前提下有效地减少处理的数据量进而降低对硬件的要求并改善无线传
感网网络性能。

Abstract: 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.
Keywords:telecommunication and information system; wireless sensor network; compressed sensing;
storage and forwarding; time delay
