The complexity of evolving DOD communication networks continues to grow as the need to support the full range of user platforms configured as ad-hoc communication networks remains as a pivotal requirement toward the development of a seamless network-centric communications infrastructure. Quantifying the end-to-end performance for these networks continues to be highly desired by the component and network designers during all phases of the development process. The complexity of such networks rarely allows one to generate this performance analytically through the application of closed-form expressions. Additionally, in-lab testing and field demonstrations have limitations in terms of scalability and cost leaving simulation as the only viable method with which to generate end-to-end performance. The simulation of ad-hoc communication networks can be challenging from a run-time performance standpoint. A variety of network characteristics contribute to this including mobility, offered traffic load, the number of nodes, the traffic mix (i.e. voice, data, video), support for multicast traffic, and the need to account for terrain. The purpose of this paper is to complete our report on the results generated to date from investigating a variety of mechanisms to improve simulation runtime performance of ad-hoc communication networks. Our initial research in this area began in September 2004 and was reported in MILCOM 2005 in "Improving Run-Time and Memory Footprint Performance in Large Scale Network Simulations".

Mr. Comparetto is a Senior Principal Engineer in the Network and Communications Engineering Center in the MITRE Washington C3 division. Over the past several years, Mr. Comparetto has focussed on the area of Modeling and Simulation, with application to mobile ad-hoc terrestrial and SATCOM networks. His primary interests include communications network performance, SATCOM link analysis, and waveform design. Prior to this, Mr. Comparetto was General Manager of Radio Dynamics Corporation where he had technical oversight over all engineering activities related to satellite systems. In this role, Mr. Comparetto supported the development of a novel approach to quantify the impact of signal interference from Mobile Satellite Service systems to fixed service receivers in the 2165 to 2200 MHz frequency regime. Mr. Comparetto has also held key positions at M/A-COM Linkabit and Stanford Telecommunications Corporations and has extensive experience working with the full range of commercial and military satellite communications systems.
