Abstract
The objective of this research is to develop a simulation approach for analyzing large-scale communication networks. Using this approach, we should be able to compare different network designs in terms of their efficiency. Also, we want to be able to decide when to stop the simulation. The simulation should be long enough for the statistics to be reliable. At the same time, the simulation should not be too long which would eventually be a waste of computer resources, if the information derived from the later observations is very less. A two-layered approach was developed to simulate large-scale communication networks. This approach was able to take care of the specific hardware connections, the reliability and availability of hardware as part of the CIN sub-model. These models were developed in GSS and were. found to be efficient in achieving independence between the c2 analyst and the CIN analyst. An approach was developed for estimating performance measures of the different communication networks, in order to compare their efficiencies. Also, a method of defining stopping conditions were suggested. Using the stopping conditions that are defined, a variance reduction technique was developed. This technique should be used very carefully. But, a more important use for the technique was found to be the possibility of determining feasible stopping conditions efficiently. This approach was applied to C3INAT and was found to work well.
