Transmission of Watermarked Image in WSN Using ELSM Algorithm

To improve the copyright protection of the digital image, the watermarking technique is used. By changing the entropy, identify the location where the secret data gets embedded into the original image. It provides less distortion and high robustness. The watermarked image is send to the receiver through the wireless sensor network. In WSN, clustering is the best technique to save the energy. In cluster-based WSN, cluster head requires more energy to receive the data from the sensor nodes and transmitting it to the base station. To maintain the lifetime of WSN, the proper selection of CH is essential. In this paper, we propose the energy-based least squares multiple algorithms. Simulation results show that the ELSM algorithm is more efficient compared to the WLSM algorithm to improve the range of bandwidth, cluster overhead, skew rate, offset rate, carrier signal, reference signal and control output signal.
