联合模拟网络编码和压缩感知的数据传输方案

基于模拟网络编码和压缩感知的思想,提出传输链路上的节点可进行同时传输以降低传输所需时隙开销,设计了一种在链状拓扑中的联合模拟网络编码和压缩感知的传输方案.基于分簇压缩感知方案可有效减少传输量的思想,提出了将无线传感器网络划分为簇,在簇间采用联合模拟网络编码和压缩感知传输方案的模拟网络编码分簇方案.与传统的压缩方案相比,该方案降低了传输量,节省了节点能耗,且减少了传输所需时隙开销,提高了系统吞吐量.

Transmission scheme through joint compressed sensing and analog network coding

Based on the theory of Analog Network Coding(ANC) and Compressed Sensing(CS), we proposed that nodes in the chain topology could transmit data at the same time to reduce time slots cost, and we designed the ANC&CS transmission scheme to be applied in the chain topology. Besides, based on the theory that clustering scheme could reduce transmissions in Wireless Sensor Network(WSN), we divided the WSN into clusters and applied the ANC&CS transmission scheme to the transmission among clusters. Compared with the traditional Compressed Sensing scheme, our scheme could not only decrease the transmission numbers to save energy, but also reduce the time slots cost to improve the network throughput.
