NetSimulyzer: a 3D Network Simulation Analyzer for ns-3

June 23, 2021
Author(s)
Evan Black, Samantha Gamboa Quintiliani, Richard A. Rouil
The increased complexity of network protocols and scenarios simulated using ns-3 is making the verification of simulation correctness and the analysis of simulation outputs a challenging task. In this paper, we present a new and flexible visualization tool

3GPP NR V2X Mode 2: Overview, Models and System-level Evaluation

June 21, 2021
Author(s)
Zoraze Ali, Sandra Lagen, Lorenza Giupponi, Richard A. Rouil
Following the successful use of sidelink in Long Term Evolution (LTE) for Proximity Services (ProSe) and Cellular Vehicular-to-everything (C-V2X), the 3rd Generation Partnership Project (3GPP) is working towards its evolution in New Radio (NR) systems in

Study of 5G New Radio (NR) Support for Direct Mode Communications

May 7, 2021
Author(s)
Fernando Cintron, David W. Griffith, Chunmei Liu, Richard A. Rouil, Yishen Sun, Jian Wang, Peng Liu, Chen Shen, Aziza Ben Mosbah, Samantha Gamboa Quintiliani
In public safety communications, direct mode communication is essential to keep first responders connected, especially when there is no network coverage. Direct mode communication is supported in Third Generation Partnership Project (3GPP) Long Term

A Comprehensive Analysis on Multicast and Unicast Performance and Selection

April 14, 2021
Author(s)
Chen Shen, Chunmei Liu, Richard A. Rouil
Multicast transmission has long been studied along with its evolved standards, but few work provides comprehensive comparisons to Long Term Evolution (LTE) unicast transmissions. With focus on LTE Multicast Broadcast Single Frequency Network (MBSFN)

UE-to-Network Relay Model B Discovery in ProSe-Enabled LTE Networks

April 6, 2021
Author(s)
Alexandre C. Moreaux, Samantha Gamboa Quintiliani, David W. Griffith, Richard A. Rouil
In this paper, we expand previous analytical models to offer a more complete representation of Model B ProSe direct discovery. Using these models, we can obtain performance metrics such as the average time a given Remote User Equipment (UE) takes to

Evaluation of Timers Related to ProSe-based UE-to-Network Relays

March 24, 2021
Author(s)
Aziza Ben Mosbah, Samantha Gamboa Quintiliani, Richard A. Rouil
User Equipment (UE)-to-Network Relay functionality was introduced in Release 13 of the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) to extend and improve user connectivity using the sidelink (SL) channels. The UE-to-Network Relay

Study of Multicast Broadcast Single Frequency Network Area in Multicast Communication

December 15, 2020
Author(s)
Chen Shen, Chunmei Liu, Richard A. Rouil, Hyeong Ah-Choi
Multicast was introduced in Long-Term Evolution (LTE) in release 8 as the technology of the Evolved Multimedia Broadcast Multicast Services (eMBMS) and has been steadily updated in the later releases. Its prominent advantage in full resource access of each

PSCR 2020_The Evolution of Direct Mode in 3GPP

October 29, 2020
Author(s)
Richard A. Rouil
Direct Mode communication remains one of the major hurdles for transitioning from Land Mobile Radio (LMR) to broadband technology. This session will start by providing some background information on 3GPP Long Term Evolution (LTE) direct mode, called

Evaluating Unicast and MBSFN in Public Safety Networks

September 3, 2020
Author(s)
Chunmei Liu, Chen Shen, Jack Chuang, Richard A. Rouil, Hyeong-Ah Choi
Public safety incidents typically involve a significant amount of group traffic and have a stringent requirement of connection reliability. Hence multicast could potentially improve network and user performance significantly, which triggered our study on

UE-to-Network Relay Discovery in ProSe-enabled LTE Networks

March 30, 2020
Author(s)
Samantha M. Gamboa Quintiliani, Alexandre C. Moreaux, David W. Griffith, Richard A. Rouil
The UE-to-Network Relay functionality was introduced to Long Term Evolution (LTE) cellular networks in Release 13. In this technology, User Equipment (UEs) acting as Relay UEs are used to extend network coverage to cell-edge and out-of-coverage Remote UEs

On Selecting Channel Parameters for Public Safety Network Applications in LTE Direct

March 26, 2020
Author(s)
Siyuan Feng, Hyong-Ah Choi, David W. Griffith, Richard A. Rouil
The Third Generation Partnership Project (3GPP) defines various pre-configured channel parameters for the Long- Term Evolution (LTE) Device-to-Device (D2D) communications with Physical Sidelink (SL) Channels. In this paper, we investigate the impacts of
