About the paper
Signal telemonitoring in Wireless Sensor Networks (WSNs) and Internet-of-Things (IoT) holds the promise to be an evolving direction in personalized medicine. The WSNs and IoT enable information telemonitoring and communications technologies play important roles in the future life. However, when design such a system, one should consider the required functionality, miniaturization, energy efficiency and etc., to make fewer resources required in WSNs and IoT. Conventional methods of data-acquisition cannot energy-effectively compress data with reduced device costs. Different with the traditional compression methods, compressed sensing (CS) takes promising steps towards these challenges. Unfortunately, the data is not sparse in time domain. Hence, current CS algorithms are extremely difficult to use directly for recovering the required signal. In order to satisfy the requirements of applications in WSNs and IoT, this study proposes an approximated l0 (AL0) norm based method to search the solution via the gradient descent method, then projects the searched solution to the reconstruction feasible set. Meanwhile, this study adopts a new wavelet threshold (NWT) based method to denoise the interference. Experimental results are provided to testify the performance of the proposed methods. The scheme if shown in Fig.1, and the compression and basis matrices are shown in Fig.2.
