Despite the importance of real-world experiments, nearly all ongoing research activities addressing video streaming over MANETs are based on simulation studies. Earlier research shows that the limited resources of mobile handhelds, which are not modeled in most network simulators, can be a severe bottleneck. The authors study the capability of a modern handheld to perform one core task, which is the forwarding of video streams. They present end-to-end video quality and network measurements, along with an analysis of resource consumption. Their studies of the recent handheld Nokia N900 show that it can forward up to 3.70 Mbps.
