Abstract

Applications of wireless multimedia sensor networks (WMSNs) require high data rates to enable delivery of quality video at any channel conditions. In order to improve the performance of video transmission over ultra-wideband (UWB) WMSNs, we first propose an optimum group-of picture bit-stream partitioning algorithm for unequal error protection (UEP) of video signals. To further enhance the proposed UEP scheme an adaptive equal-unequal error protection is also proposed. Performance results in terms of peak signal-to-noise ratio (PSNR) reveal that the proposed schemes outperform the conventional equal error protection and UEP schemes by up to 7 dB.
