Abstract

A new call admission control scheme for satellite networks operating at frequencies above 10 GHz is proposed. The major factor impairing the link performance at these frequencies is rain attenuation, a physical phenomenon exhibiting both spatial and temporal variation. Exploiting the predictability of the satellite channel, a new call is accepted provided that there are sufficient resources for existing and new users to guarantee QoS. The performance of the proposed scheme is investigated using Markov chain analysis. Finally, the upper bound of the call blocking probability is determined.
