无线传感网中一种基于压缩感知的数据存储机制
A DATA STORAGE MECHANISM BASED ON COMPRESSIVE SENSING IN WIRELESS SENSOR NETWORKS
摘要
Abstract
To realise distributed data storage with energy efficiency is a focus in wireless sensor networks research.Aiming at the disadvantages of existing storage algorithms,we propose a compressive sensing-based new data storage mechanism.First,it measures the data of each sensor node based on compressive sensing technology,then it selects Ns nodes randomly from the network as the source nodes,and broadcasts to their neighbours their own measurements with probability p,which makes the data collectors can gather the measurements of whole network by only accessing to a small number of nodes.Finally,under the premise of ensuring data reconstruction precision,the efficient data storage is realised through the optimisation of measurement matrix and forwarding probability p.Theoretical analysis and simulation experimental results show that,our method is effective.It is better than the traditional methods in times of data transmission and energy efficiency.关键词
