What is LENA exactly?

[Hadeel Alghafari]

Hi,

Please can anybody tell me what is LENA exactly? and if I want to simulate a LTE network that includes Femtocells can I do that with LENA ?

?and as I read that NS3 in general supports LTE networks, so what is the difference between NS3 (as it supports LTE networks) and LENA

Hi, 

This is taken from LENA website:

LENA is an open source product-oriented LTE/EPC Network Simulator that allows LTE small/macro cell vendors to design and test Self Organized Network (SON) algorithms and solutions. Target applications for LENA 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. LENA is based on the popular ns-3 network simulator for internet systems. The development of LENA is open to the community in order to foster early adoption and contributions by industrial and academic partners.

- See more at: http://networks.cttc.es/mobile-networks/software-tools/lena/

The source code of LENA, since milestone M8 has been merged in ns-3.19, which in other words means that the LTE module in ns-3.19 is the LTE module implemented in the LENA project.

You can use LENA or NS-3 for your simulations. They are the same. The differences are in the development versions of the two projects. For example some aspects of LTE (e.g. new schedulers) are first introduced in the LENA development tree, tested and then merged in the NS-3 development tree. Similarly with the NS-3 updates (first in ns-3-dev and then in the LENA code).

Thanks a lot ..

Hi,

Would you also please explain how can I have the source code of the Lena( not the simple one in NS3 src) and how can understand the simulation in NetAnim,

I appreciate any help,

Shadi

The LENA project has finished some years now.
The 'simple' ns-3 you mention, contains the latest LTE contributions.

Regarding NetAnim, there is enough documentation online. Notice the limitation it has regarding LTE module.

 Hi Konstantinos, 

Would you please help me in finding a way to solve my problem?

I want to run mptcp example in NS3 and I tried to install the Advanced version of ns3-dce, bake.py download worked completely but 

bake.py build has ccnx problem, 

What should I do?

   This may reduce the  functionality of the final build. 

   However, bake will continue since "ccnx" is not an essential dependency.

   For more information call bake with -v or -vvv, for full verbose mode.

No command 'bake' found, did you mean:

 Command 'jake' from package 'node-jake' (universe)

 Command 'make' from package 'make' (main)

 Command 'cake' from package 'cakephp-scripts' (universe)

 Command 'rake' from package 'rake' (main)

 Command 'fake' from package 'fake' (universe)

 Command 'bmake' from package 'bmake' (universe)

bake: command not found
