✦ Synopsis
This paper extends previous research e!orts related to the simulation performance modelling and analysis of satellite communication networks. Speci"cally, the use of low earth orbit (LEO) satellite networks for personal communications is examined. Six di!erent satellite constellation con"gurations are investigated in a packet-switched operating environment. Performance metrics examined are the end-to-end packet delay and the utilization of satellite channels in the dynamic environment. Realistic and accurate models of the physical satellite network and its terrestrial transmitters require that numerous operating characteristics and assumptions be speci"ed. These are based on proposed design requirements of commercial systems, such as Iridium. Via the use of simulation, we show the relative delay and utilization performance of di!ering satellite network architectures. From these simulation models, mathematical metamodels are derived for the system delays. These innovative models are used to predict the delay performance of di!erent network architectures not previously simulated. Comparison of these metamodels with simulation results show that metamodels provide an accurate means for performance prediction.
