NIST Releases Tool to Advance Device-to-Device for LTE
Thursday, October 26, 2017 | Comments

The National Institute of Standards and Technology (NIST) announced a new computer modeling tool that can virtually recreate an emergency scenario and track performance features of broadband devices.

The NIST tool uses ns-3, an open-source network simulation software, giving researchers the ability to virtually recreate any emergency scenario and draw on a variety of environmental, structural, technological and human behavioral factors that could impact the performance of future Long Term Evolution (LTE) cellular devices.

Models produced by the NIST tool address performance issues such as voice traffic, location, networking and the use of protocol emergency buttons. A graphical user interface (GUI) can be used with the tool so that results from the models can be viewed as animations.

“We hope that the new modeling tool will be widely used by researchers who want to experiment with different ways to optimize the three key mission-critical voice capabilities, by manufacturers who want to ‘field test’ device designs without having to build multiple versions, and by emergency management officials who want to educate first responders under their command about the advantages of LTE communications in hazardous situations,” said Richard Rouil, a computer engineer in NIST’s Communications Technology Laboratory (CTL) who helped create the tool. “Most importantly, the tool makes it possible to develop, test and refine standards for the next generation of emergency response communications devices concurrently with, rather than after their development.”

A collaborative effort with the University of Washington will work toward integrating the NIST module directly into the ns-3 software to enable expansion of the tool’s modeling capabilities. Funding for this project comes from a NIST grant awarded in June to the University of Washington as part of the Public Safety Innovation Accelerator Program.

The NIST LTE Device-to-Device Communication Model for ns-3 is available for downloading. A NIST paper titled “Implementation and Validation of an LTE D2D Model for ns-3” is here.

The free ns-3 software is here. More information including a video simulation is here.
