Simulation of large-scale heterogeneous communication systems

Abstract

Large-scale hybrid networks that include wireless, wired, and satellite-based communications are becoming common in both military and commercial situations. This paper describes a scalable simulation environment that effectively utilizes parallel execution to reduce the simulation time of detailed high-fidelity models of large communication networks. The paper also presents a set of case studies that evaluate the performance of large wireless networks with thousands of nodes and compares the impact of different lower layer protocols on the performance of typical applications.
