Abstract: Multiple description coding can prevent the loss of the image data and the dependence of the single share data effectivcly,which can ensure the quality of the images received by the terminal nodes. Network coding can improve the network bandwidth utilization rate effectively. In order to adapt to the reliable transmission and save the bandwidth of the wireless sensor network, this paper proposed the ideology of combining multiple description coding with network coding, which takes multiple paths transmission as a foundation.
