Estimate of Quality of the Ad Hoc Network Proactively for Video Transmission

Real time Video transport over ad hoc network poses a great challenge due to the high variability of the network bandwidth. In this paper, to adjust rate in time according to the change of the quality of the channel of ad hoc network, we propose a scheme which judge the quality of the wireless channel proactively. The value of signal strength is used to be an important factor for judging the quality of wireless channel. Experiment results show that the averages of BER and PER can be reduced by employing this scheme.
