Abstract :
In this paper, the problem of transmitting embedded bitstreams over wireless packet networks is considered. In particular, the authors address the problem of optimal energy allocation in video streams employing fixed-size packets, and analyze the performance under different modulation schemes. Results obtained for the transmission of MPEG-4 FGS bitstreams show the impact of the proposed method in different modulation schemes.
