jLTE Simulator

Overview

The jLTE Simulator is a network simulator designed to simulate the physical layer of an LTE network consisting of a number of base stations (eNodeBs) and users (UEs). It was designed specifically for the research project investigating the effect of co-ordinated scheduling in LTE networks. Further documentation is included within the thesis itself which is availabe at downthewire.co.uk.

Getting Started

This project was built using Apache Maven which can be downloaded from maven.apache.org and installed by following the instructions on that page.

Before the system can be fully compiled Michael Thomas Flanagan's Java Scientific Library must be installed. The jar file must be downloaded and installed into your local maven repository. This can be achieved using the following commands:

wget http://www.ee.ucl.ac.uk/~mflanaga/java/flanagan.jar

mvn install:install-file -Dfile=flanagan.jar -DgroupId=flanagan -DartifactId=flanagan -Dversion=1.0 -Dpackaging=jar

The project can then be compiled in the same fashion as any maven project using the following command:

mvn compile

Generating Fading Data

In order to use the simulator run the tests some auxiliary fading data must be generated. This data is used to model the signal quality of the wireless channel between each user and base station. The location of the fading data is specified in the lte.fadingPath configuration option in the system.properties config file which can be found in the src/main/resources/ directory.

The fading data can be generated by running the GenerateFading main class in the package uk.co.downthewire.jLTE.fading. This can be executed in maven using the command 'mvn exec:java'. Note that significant heap space can be required to generate adequate fading data.

Running Tests

Having generated the fading data required the tests can now be run using the standard maven command:

mvn test

The test suite includes both unit and integration tests which will take ~10 minutes to complete.

Running the Simulator

Now that the tests are all passing you can begin to run your own network scenarios. Some example scenarios are defined as part of the test suite, see the src/test/resources/ directory. Each scenario contains a config file for the UEs and a config file for the eNodeBs. A number of settings are also defined in the system.properties configuration file.
