ABSTRACT: The trade off between the energy consumption and the quality of the
received image should be considered as a main point in the techniques design in
Wireless Sensor Network (WSN). This paper analyzes the performance of multiple
image encryption algorithms with different approaches. And also, it introduces
two proposed modulation techniques to enhance the performance of WSN. These two
techniques merge both the image and the audio in one signal. The merging
process enhances the energy consumption data rate. In addition, it removes the
effectiveness of the jamming completely from both the reconstructed image and
reconstructed audio signal at the receiver. So, the receiver will reconstruct
the image without jamming effectiveness. The paper introduces a proposed audio
encryption algorithm. The use of encryption algorithms for both image and audio
signals with the merging process enhances the security level. Popular metrics
are used to compare between these image encryption algorithms and also to show
the benefits from these enhancements. The results show the preference of one of
these image encryption algorithms to others. And also, the merging process
enhances the bit rate to high level.
