Transmission scheme through joint compressed sensing and analog network coding
|
Abstract:
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.
