Abstract:

A novel bandwidth prediction and control scheme is proposed for video transmission over an ad hoc network.The scheme is based on cross-layer, feedback, and Bayesian network techniques.The impacts of video quality are formulized and deduced.The relevant factors are obtained by a cross-layer mechanism or Feedback method.According to these relevant factors, the variable set and the Bayesian network topology are determined.Then a Bayesian network prediction model is constructed.The results of the prediction can be used as the bandwidth of the mobile ad hoc network(MANET).According to the bandwidth, the video encoder is controlled to dynamically adjust and encode the right bit rates of a real-time video stream.Integrated simulation of a video streaming communication system is implemented to validate the proposed solution.In contrast to the conventional transfer scheme, the results of the experiment indicate that the proposed scheme can make the best use of the network bandwidth;there are considerable improvements in the packet loss and the visual quality of real-time video.
