Medical images transmission over Wireless Multimedia Sensor Networks with high data rate

Abstract

This paper presents several proposed scenarios for medical image transmission over Wireless Multimedia Sensor Networks with multi-level security tools and Unequal Error Protection (UEP) technique to provide highly secure and improved medical images transmitted over the wireless link. The proposed scenario is based on embedding the medical images with audio watermarking technique. The audio signal is presented as a medical report for the embedded medical image. The audio watermarking in this paper used the Singular Value Decomposition technique to hide the image as a watermark into the audio cover signal to form the watermarked signal. This combined signal is transmitted using the UEP technique by employing different error control schemes and different packet lengths to enhance the quality of extracting encrypted/unencrypted medical images. The results show that the quality of the extracted medical images with encoded packets is better, also, the encryption of different error control schemes employing with the image enhances the extracted image and its quality.
