Automotive Network and Simulation Models
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 simulation and modeling 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.
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 tools to assist development of their systems.
The Korean Automotive Technology Institute (KATECH) has selected EXata to integrate with their driving simulator. EXata will provide a simulation model 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.
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, 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.
