Aiming at the special circumstance in which UAVs swarm are used in the mode of battlefield extending, a message delivery scheme called AWJPMMD (ARIMA-WNN Joint Prediction Model based Message Delivery) is proposed. In this scheme, the LET (Link Expiration Time) of the center node and the proxy node is calculated by high precision GPS information, then the LET at next moment is predicted by ARIMA-WNN (Autoregressive Integrated Moving Average model - Wavelet Neural Network) Joint Prediction Model. Finally, the process of message delivery is affected by the predicted value of LET and other parameters. The target information is sent to the UAVs ground station in form of store-and-forward by the message delivery process. Simulation shows that this scheme can provide higher message delivery ratio and this scheme is more stable.
