基于压缩感知的无线传感网络数据压缩
Data compression based on compressed sensing in Wireless Sensor Networks
摘要
Abstract
Wireless Sensor Networks(WSN)are responsible for sensing, collecting, processing and monitoring environ-mental data, but resource is easily limited. The newly emerging Compressed Sensing(CS)theory holds that sparse signals can be exactly reconstructed with high probability from a small amount of non-adaptive linear measurement through opti-mization. A data compression method which is dependent only on the structure and content of the signal, rather than the bandwidth of the signal is designed by sparse random projections through network coding. The results of simulation show that this system not only improves the efficiency of WSN communication by reducing packets to 30% number of nodes, but also reduces the system energy consumption under the error requirement.关键词
