Abstract
Video applications are becoming more popular over wireless ad hoc and sensor networks (WAHSNs). However, due to limited resources, WAHSNs need an efficient video-compression technique in order to minimize the amount of data and maximize the quality of video to be transferred over the network. To this end, we have performed NS2 simulations to evaluate the performance of MPEG-4 (MPEG-4 Part 2) and H.264 (MPEG-4 Part 10) video codecs using EvalVid framework and toolset, AODV routing protocol and constant bit rate (CBR) traffic. The results of simulations show that H.264 outperforms in terms of peak signal-to-noise ratio (PSNR) and end-to-end delay which makes it perfect for video applications over WAHSNs.
