Abstract: This paper proposed a reliable transmission control mechanism based on the large data collaborative forecasting power function regression curves and random linear network coding to provide high reliability,resource utilization and quality of service for multimedia data transmission,which is suitable for wireless multimedia sensor networks.Firstly,according to the data characteristics and dynamic multimedia network topology,a prediction model was presented based on the power function regression curve.Then the video frames were used as a unit for network coding at the network layer and the physical layer.Finally a collaborative network-based prediction and coding big reliable data transmission control mechanisms were established.Through mathematical analysis and simulation,the proposed mechanism was evaluated by analysis of system performance with the traditional mechanisms.The conclusion proves the superiority of the proposed mechanism.
