Abstract:
A novel file delivery scheme over a Ka-band channel is proposed, which is heavily dependent on weather around the earth’s atmosphere. The proposed scheme based on CFDP is designed to resist the influence of weather conditions by the weather-forecasting. In this work, the condition-forecasting model that the weather sequence is forecasted through the first two states is constructed, demonstrated by the theoretical analysis and furthermore, implement of forecasting algorithm is also carefully researched and designed. Simulating results show that the file delivery time of selection-waiting CFDP with weather-forecasting is reduced effectively compared with traditional CFDP.
