Introduction

• GloMoSim is the Global Mobile Information Systems Simulation Library from UCLA. Specially oriented to simulate wireless, ad-hoc

networks.

• It can be obtained from http://pcl.cs.ucla.edu/projects/glomosim/ .

2

Outline

• Installation on a UNIX-like system. Specific examples for RPM-based Linux

systems.

• Installation on a Windows NT-kernel system.

• Running a basic simulation.

• Seeing the results – GloMoSim VT.

4

Installation on a UNIX-like System

• We have chosen to show the installation for a RPM-based Linux system. Red Hat Mandrake Many others…

• Why does this matter?

5

• Un-gzip the distribution package.

• Untar the distribution package.

• Install the glomosim and parsec directories into /usr/local.

6

• Set your path environments (assuming you use tcsh or csh). PCC_DIRECTORY PATH

• Check if pcc works from anywhere.

• Check your pcc environment by pcc –env.

7

• Go to glomosim\main and do make.

• Once the make is complete, GloMoSim is ready to use, and lives in bin.

• Don’t forget to compile the Java GUI, in java_gui.

8

Demonstration of GloMoSim Installation on Linux

We will resume the presentation after the demonstration.

Installation on a Windows NT-kernel System

• Beforehand: Visual Studio 6.0 w/ sp4 Java SDK 1.2+

JRE (Java Runtime Environment) is

INSUFFICIENT

• Un-gzip the distribution package.

• Untar the distribution package.

• Install the glomosim and parsec directories into %programfiles%\.

11

• Set your path environments. PCC_DIRECTORY

C:\Program Files\glomosim-2.03\parsec\windowsnt-4.0-vc6

PATHC:\Program Files\glomosim-2.03\parsec\

windowsnt-4.0-vc6 \bin Visual Studio

vcvars.bat

• Check if pcc works from anywhere.( Check your pcc environment by pcc –env )

12

• Go to glomosim/main and do makent.bat.

• Once the make is complete, GloMoSim is ready to use, and lives in bin.

• Don’t forget to compile the Java GUI, in java_gui.( javac *.java )

Running a Basic Simulation

• GloMoSim depends on its config.in file.

• Let’s go through some of the basic variables in config.in.

• Most of them are self-explanatory, and those that aren’t are described in config.in.

• SIMULATION-TIME Total time elapsed

inside of simulation.

• TERRAIN-DIMENSIONS The area you are

simulating in.

• NUMBER-OF-NODES The number of nodes.

16

• NODE-PLACEMENT The way the nodes are

placed in the terrain… random, grid, uniform, or by input file allowed.

• MOBILITY Movement of nodes.

Can be none, random-waypoint, by trace, or by pathloss matrix.

• MAC-PROTOCOL Defines what MAC

you use. 802.11, MACA, CSMA, TSMA supported.

• ROUTING-PROTOCOL Bellman-Ford, AODV,

DSR, LAR, WRP, Fisheye, ZRP and static supported.

17

• Parameters for reporting statistics (YES/NO selection): APPLICATION-

STATISTICS TCP-STATISTICS UDP-STATISTICS ROUTING-

STATISTICS NETWORK-LAYER-

STATISTICS

MAC-LAYER-STATISTICS

RADIO-LAYER-STATISTICS

CHANNEL-LAYER-STATISTICS

MOBILITY-STATISTICS

GUI-OPTION GUI-RADIO GUI-ROUTING

18

• Other files of interest: glomo.stat is produced by the simulation, and

contain all statistics. Easily filterable because things are printed with the layer and node they belong to.

mcast.conf contains multicast group information.

Seeing the Results – GloMoSim VT

• The Visualization Tool is a Java-based tool that allows you to see the happenings of your simulation.

• To use the tool: Run GloMoSim inside of the VT. Write a trace file. Play back the trace file.
