In this paper, we first consider the quality of service
problems in heterogeneous wireless networks for sending the video
data, which their problem of being realtime is pronounced. At last,
we present a method for ensuring the endtoend quality of service at
application layer level for adaptable sending of the video data at
heterogeneous wireless networks. To do this, mechanism in different
layers has been used. We have used the stop mechanism, the
adaptation mechanism and the graceful degrade at the application
layer, the multilevel congestion feedback mechanism in the network
layer and connection cutting off decision mechanism in the link
layer. At the end, the presented method and the achieved
improvement is simulated and presented in the NS2 software.
