This module provides extensions to the LTE including Device to Device (D2D) capabilities, as well as new propagation models and applications related to public safety communications.

The current model is based on ns-3.40 release and supports the following additional features:

• Out of coverage synchronization
• In and out of coverage D2D Discovery
• In and out of coverage D2D Communication
• Various 3GPP based propagation models
• detailed on-network and off-network MCPTT model for D2D operation
• UAV mobility energy model
• HTTP application model
• UE-to-Network Relay model
• video streaming model
• Additional examples for multi-cell and partial coverage
• Large scale scenarios

Future work:

The future has now arrived! Many of these models are now available for 5G NR Sidelink Mode 2. Check out the psc and nr-prose apps for more details.

About the Model:

The model was initially developed and maintained by the Public Safety Communication Project Group of the Wireless Networks Division (WND) at the Communication Technology Laboratory (CTL) of the National Institute of Standards and Technology (NIST) - U.S. Department of Commerce. For further information about the research conducted by the group, please refer to the following website: https://www.nist.gov/programs-projects/network-modeling-public-safety-communications

The integration of the initial ProSe module with the LTE and buildings module, as well as the creation of additional examples and tests, and contributions to on-network MCPTT support, was assisted by CTTC and the University of Washington. This work was performed under the financial assistance award 70NANB17H170 and 70NANB20H179 from U.S. Department of Commerce, National Institute of Standards and Technology.
