Joint Source-Channel-Authentication Resource Allocation for Multimedia overWireless Networks
In our previous work (Li et al., 2006), we have presented unequal authenticity protection (UAP), the methodology of effective protecting multimedia stream transmitted over error-prone wireless networks. In this paper, we extend the previous analysis and consider integrating UAP into the joint source-channel coding (JSCC) framework to achieve optimization of end-to-end quality of media content. We further illustrate the effectiveness of this system using an implementation on progressive JPEG coder.
