Wireless Cyberwarfare: Why Mobile Networks Are The Most Vulnerable and What To Do About It (whitepaper, 2009)
Cyberspace as a warfare domain is rapidly being viewed as equal to land, sea, air, and space. This white paper describes recent trends in cyberwarfare, the specific weaknesses of wireless networks, and what is being done to improve defensive and offensive wireless cyberwarfare strategies.

How to Develop Predictable On-the-Move Communications Faster and at
Lower Cost Using Real-Time Network
Emulation (whitepaper, 2008)
This white paper outlines the key challenges to developing predictable on-the-move communications, reviews historical approaches to on-the-move network design, and presents a new approach––real-time wireless network emulation––as the solution to gaining the experience of meeting service requirements and overcoming technical obstacles faster and at much lower cost than designing in a trial-and-error vacuum.

EXata: An Exact Digital Network Replica for Evaluation, Training and Operations of Network-centric Systems (technical brief, 2008)
To greatly streamline and reduce the cost of rolling out new wireless technologies, emulation provides an exact digital replica of a real network or part thereof. Emulations using Exata software allow for the whole or a part of a real network to be replaced by a counterpart representation in software form. Emulation is a faithful representation of the system being replaced, and interfaces seamlessly with the rest of the system, even for the most complex of networks.
This white paper will a) describe what constitutes an exact digital replica, b) explain in technical terms the specific requirements of next generation wireless networks and how that translates into requirements of emulators, and c) provide four EXata use cases that demonstrate the need for highest fidelity network stand-ins.

Information Warfare (2008)
Information
Warfare is defined as the offensive and
defensive use of information and information
systems to deny, exploit, corrupt, or destroy an
adversity’s information, information-based processes,
systems and computer networks.
There is a need for next-generation network technologies
to be thoroughly tested and evaluated before
being deployed. Military and civilian networks
need to be deployed with confidence that they
will perform as envisioned in the lab. With this goal in mind, wireless network technologies must be developed and tested in as realistic an environment as possible, one that factors in all
the wireless networks that will be in operation.
This white paper will discuss ways in which
wireless networks are vulnerable to attack, as
well as ways that they can be protected. Next,
we will introduce the concept of network simulation
and emulation software for test and evaluation
of information warfare technologies. Finally,
we’ll provide data from network simulations that
demonstrate the value of detailed modeling of
cyberwarfare for thorough testing and validation.

Test and Evaluation of Network-centric Systems (2007)
New techniques employing highest fidelity,
real-time network emulations are changing the
way that network-centric systems are tested
and evaluated. After early stage, abstracted
simulations and before late stage full prototype
testbeds, emulation plays an important role
in evaluating network constructs. From the
component level to the system-of-systems level,
emulation enables network designers to test
and evaluate the system, greatly reducing the
cost and effort required to thoroughly test and
validate throughout the design cycle.
Not all network simulators are capable of true
emulation, however. To be a true replacement
for a network, an emulation must support realtime
speed, full packet fidelity, and transparency.
Included in this White Paper is a case study featuring L-3 Communications' Multi-Role Tactical Common Data Link Network and how they use QualNet to develop, test and evaluate the technology.
QualNet is a network simulator that supports
true network emulation. With parallel execution
and highest fidelity models, QualNet has the
scalability and interactivity required to test and
evaluate the most advanced network-centric
systems.

Network Centric Warfare White Paper (2006)
As warfighting becomes increasingly modernized through the use of network-centric warfare, communication becomes more and more critical to success. Adding communication effects to existing war games can be achieved through HLA, DIS, and TCP/IP sockets. We describe how the QualNet network simulator can be integrated to OTB, STRIVE, and MANA using HLA, DIS, and TCP/IP sockets respectively. Finally, we provide quantitative results from a MANA-QualNet simulation that show that detailed communication models greatly affect the outcome of battle simulations, generally for the worse.

MANET Scalability White Paper (2005)
Published at MILCOM 2004
co-authored by SNT and US Army RDECOM CERDEC STCD
As wireless ad hoc networks grow in size and complexity, the need to study and comprehend the scalability and behavior of these systems and their protocol components becomes essential. This paper presents a comprehensive study on the performance of common MANET (mobile ad hoc network) routing protocols in large-scale networks. The routing protocols used in this study include AODV, DSR, OLSR, and ZRP, which represents a good mix of reactive, proactive and hybrid protocols.

Parallel Execution White Paper (2002)
Historically, modelers have been forced to choose either fast simulation or accurate results when working in discrete event simulation. We discuss commonly used methods of improving performance to avoid this tradeoff, including what the prerequisites are and how optimization is achieved. Parallel execution is arguably the best solution, and this paper discusses how a sequential model is "parallelized" to be executed in parallel. Finally, we present quantitative results from the successful parallellization of models in QualNet, a discrete event simulation software product for modeling networks. After reading this paper, modelers should be equipped to assess their model's potential for performance gains through parallelization, as well as alternatives for better performance outside of parallel execution.

Speed and Scalability White Paper (2002)
New network modeling software tools are proving that faster simulation speeds and greater scalability are achievable through smart architecture and optimized memory management. We discuss the critical factors that determine the speed of simulation, which is often the deciding factor in choosing a tool. We also show that speed and scalability are directly linked. Scalability means the simulator can support large volumes of traffic, complex node mobility and hundreds or thousands of devices and connections. We discuss how software developers build scalability into simulators. Finally, we give examples of the level of speed and scalability achievable with QualNet, a network simulator designed from the outset for maximum speed and scalability, with real-time simulation as an achievable goal.
