A program based on compression and difference transmission for image acquisition in wireless sensor networks
A program based on compression and difference transmission for image acquisition in wireless sensor networks has been proposed in this article.Node captures image and compresses the image in the format of JPEG,while based on the time redundancy of images at fixed point,eliminates the correlation between collected image and reference image using difference algorithm,and then the extracted variation will be filtered by threshold,the result is called difference which is the final data carried out in the network,the gateway node or remote server reconstructs image according to the information received and reference image.Simulation results show that when we collect image in wireless sensor networks,the program can significantly reduce the amount of data,save network resources,thus the lifetime of network can be prolonged.
