In Geostationary Earth Orbit (GEO) satellite networks, the delay of packets queued in satellite terminals in the return-link is a critical factor to degrading the quality-of-service. In this paper, we suggest two unbiased traffic forecasting models, which belong to a family of commonly used time-series models, based on the first-and secondorder variations of traffic, and develop new Demand Assignment Multiple Access (DAMA) protocols based on the proposed traffic forecasting models in order to improve the delay of packets. We compare the delay and throughput performance of the proposed DAMA protocols with that of two previous protocols under the two traffic models,SupFRP and PowON_PowOFF models, for various parameters setups. Simulation results show that the proposed protocols significantly improve the delay compared to previous DAMA protocols. This implies that, in the proposed protocols, by accurate estimation of traffic demand, valuable resources are more properly allocated to satellite terminals so that the amount of resources allocated, but not actually used for traffic transmission, can be reduced: ultimately, this improves the transmission delay of those terminals with higher traffic demand.
