Network Modeling

Intelligent Transportation

SCALABLE is known for providing unique network modeling and simulation software systems to commercial enterprises, government and defense agencies, research organizations and educational institutions around the world. With a strong focus on simulation modeling and analysis, our software helps our customers understand the impact of upgrading their networks and applications to the latest standards.  It also reflects our ongoing efforts to lower the cost of modeling and analysis of complex computer networks, while providing more insight into the key factors that affect their performance and reliability.

One way that SCALABE is utilizing our network modeling and simulations tools is to help make vehicles safer by focusing on Intelligent Transportation Systems. Intelligent Transportation Systems, which included vehicle-to-vehicle and vehicle-to-infrastructure communications, is a new technology to improve safety on the road and avoid accidents by relaying information between vehicles in the same areas using applications on Dedicated Short Range Communications (DSRC) radios over 802.11p. Wireless communication among vehicles, and between vehicles and infrastructure, promises to greatly reduce collisions and loss of life in the future. These systems can make drivers (human or autonomous) aware of dangers that exist outside their visual or sensory field-of-view, for example a vehicle speeding toward a red light in an intersection your own vehicle is about to cross. To help address these needs, we have developed an 802.11p network model that works in conjunction with QualNet and EXata to support this research.

Network Modeling

Our network modeling capabilities will help with researching  security, interoperability of devices, radio interference or network congestion that could affect safety, cyber vulnerability, performance, liability, and others issues. A preliminary version of our model is already in use in the USA and Asia to support this research, and we are starting to see interest from vehicle manufacturers to acquire our network tools to assist development of their systems.

Network Simulation Models for the Virtual World

The Korean Automotive Technology Institute (KATECH) has selected EXata to integrate with their driving simulator. EXata will provide simulation models of the communications, using its built-in Wireless Access in a Vehicular Environment (WAVE, 802.11p) protocol model, and also models interference, fading, and path loss in rural and urban environments. Wireshark is used with EXata for packet sniffing, and to check the performance and interoperability of actual WAVE devices.

Network Modeling
The system makes use of EXata's scalability and simulation modeling and analysis capabilities and can represent scenarios with thousands of vehicles. EXata is helping KATECH investigate and solve many vehicle communications development issues in their lab with our network tools, by representing multiple real-world environments without the risk of accidents using computer network models. The savings to KATECH in terms of cost, set-up time, analysis time, and physical space for testing are significant and the safety it will provide is invaluable.

EXata is a comprehensive suite of tools designed for network emulation of large wired and wireless networks. It uses network emulation and simulation models to predict the behavior and performance of networks to improve their design, operation, and management. EXata provides a cost-effective and easy-to-use alternative to physical testbeds that typically have high equipment costs, complex setup requirements and limited scalability.

For info on QualNet Read More

QualNet is a planning, testing and training tool that "mimics" the behavior of a real communications network. Simulation models are a cost-effective tool for developing, deploying and managing network-centric systems throughout their entire lifecycle. Users can evaluate the basic behavior of a network, and test combinations of network features that are likely to work using simulation models. Our network simulator software tool provides a comprehensive environment for designing protocols, creating and animating network scenarios, and analyzing their performance.
