An ns-derived GEO satellite network simulator: features, capabilities, results

The paper presents a GEO satellite network simulator developed upon the 'network simulator' (ns) platform. Initially, its objective was the investigation of the interaction of the transmission control protocol (TCP) with the data link layer in satellite networks. However, it has evolved to a simulator capable of addressing a wide range of issues that arise in current and future satellite networks. Its features are outlined and its capabilities are described and demonstrated via representative results.
