Abstract
Network-Centric Warfare (NCW) is an objective of the Department of Defense (DoD). By networking large numbers of soldiers, sensors, vehicles, and other equipment, NCW will create an explosion of data in DoD networks. By the same token, Mobile ad hoc networks (MANETs) represent a critical technology for the Armys NCW vision. MANETs are currently an unproven technology that have not been modeled at scales relevant to realistic tactical operations. While research toward understanding the emergent properties of MANETs is progressing, we are far from realizing successful deployment of MANETs even at smaller scales (hundreds of nodes), and this leaves many open questions in realistic settings. Satisfactory evaluation of the technologies supporting these scenarios will not be realized without the development of accurate computer simulation models. These models will involve thousands, perhaps hundreds of thousands of nodes. Such models create prohibitively large state spaces to be accommodated under the current state of the art. Parallelization of network simulation computation offers little benefit due to the end-to-end nature of applications. In addition to the difficulties created by excessively large state spaces, measurements from communication networks indicate that traffic patterns can be bursty and complex [1]. This leads to extremely long simulation time intervals. Standard statistical techniques used in estimating these intervals are not always applicable.
