About MONET group and its contribution to ns-3 project

The Mobile Networks group in CTTC is a group of 10 highly skilled researchers, with expertise in the area of mobile and computer networks, ML/AI based network management, SDN/NFV, energy management, performance evaluation. Our work on performance evaluation started with the design and development of the LTE module of ns-3.

The ns-3 LTE module, commonly referred to as LENA, combines a simulated channel and physical layer model with an implementation of the LTE and EPC protocol stack that closely follows 3GPP specifications. Most of LENA was developed between 2011 and 2013 as part of an industrial project funded by Ubiquisys Ltd. (now part of Cisco) and carried out by CTTC, with the aim of developing an open source product-oriented LTE/EPC Network Simulator allowing LTE small/macro cell vendors to design and test Self Organized Network (SON) algorithms and solutions. Target applications for the ns-3 LTE module include the design and performance evaluation of DL & UL Schedulers, Radio Resource Management Algorithms, Inter-cell Interference Coordination solutions, Load Balancing and Mobility Management, Heterogeneous Network (HetNets) solutions, End-to-end QoE provisioning, Multi-RAT network solutions and Cognitive LTE systems. Carrier Aggregation was recently added to the mainline ns-3 development tree, for inclusion in the next official release. The Mobile Networks group maintains a strong commitment with the ns-3 community in the area of LTE and its evolutions and NR, and has received funding from different companies besides Ubiquisys, like the WiFi Alliance, Spidercloud Wireless, Interdigital, the National Institute of Standards and Technologies, the Google Summer of Code, the Lawrence Livermore National Lab and many EU projects funded in the framework of FP7 and H2020 and in the context of 5GPPP.

Currently we have open projects and developments in the areas of:

  • unlicensed LTE (Licensed-Assisted Access and LTE-U),
  • Public Safety Communications,
  • New Radio,
  • New Radio in unlicensed bands (NR-U),
  • LTE evolutions,
  • New Radio Vehicle to Everything communications (NR V2X)

About CTTC

The Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) is a public, non-profit research institution based in Castelldefels (Barcelona), resulting from a public initiative of the Regional Government of Catalonia (Generalitat de Catalunya). Research activities, both fundamental and applied are organized onto four research divisions: Communication Networks, Communication Systems, Communication Technologies and Geomatics. Since its creation in 2001, CTTC has participated in more than 200 projects funded by European, Spanish or Catalan administrations or by direct contracts with industry, in the fields of, among others, 4/5G broadband communication systems, embedded systems, next-generation all-optical transport networks, software defined networking, satellite communications, positioning systems, M2M communications, smart grids. CTTC also develops strategic internal research projects for proof of concept and experimental prototypes.

In terms of scientific production, the CTTC annually produces over 60 and 150 papers in peer-reviewed journals and international conferences, respectively. Currently more than 100 people work at CTTC. In addition, CTTC hosts a pre-doctoral research program that since its creation has provided scientific guidance to more than 50 students, and produced more than 40 PhD thesis, many of them awarded with prizes from academic institutions or technical societies. CTTC also manages an IPR portfolio of 67 granted patents, belonging to 20 families, awarded in different countries in EU, USA, Japan, Hong Kong, and China.
