A recent article by Watts and Dodds raises the question of whether or not the spread of information and change of opinions in a social network depend on the existence of “influentials.” We have developed a software simulation platform to analyze the impact of word-of-mouth and social networks on marketing and advertising. We use our simulation platform to test the relative impact of the structu...

Distributed Mission Training is a promising technology in support of training in general and within DoD in particular. Architectural considerations (interplay of hardware and software) is instrumental given high demands for network bandwidth and computing resources in relation to proliferating software complexity. This paper proposes a co-design modeling and simulation methodology and environme...

The paper considers an approach to modeling and simulation of Distributed Denial of Service (DDoS) attacks fulfilled by a group of malefactors. The approach is based on combination of “joint intentions” and “common plans” theories as well as state machines. The formal framework for modeling and simulation of DDoS) attacks is presented. The architecture and user interfaces of the Attack Simulato...

Network simulator software tools are often used to model the behaviors and interactions of applications, protocols, packets, and data links in terrestrial communication networks. Other software tools that model the physics, orbital dynamics, and RF characteristics of space systems have matured to allow for rapid, detailed analysis of space communication links. However, the absence of a unified ...

In this work, a control-oriented sewer network model is presented based on a hybrid linear modeling framework. The model equations are described independently for each network element, thus allowing the model to be applied to a broad class of networks. A parameter calibration procedure using data obtained from simulation software that solves the physically-based model equations is described and...
