2
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/pro
  jects/glomosim/ .

3
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.

5
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?

6

• Un-gzip the distribution package.
• Untar the distribution package.
• Install the glomosim and parsec directories into
  /usr/local.

7

• 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.

8

• Go to glomosim\main and do make.
• Once the make is complete, GloMoSim is ready to
  use, and lives in bin.
• Dont forget to compile the Java GUI, in java_gui.

9
Demonstration of GloMoSim Installation on Linux

• We will resume the presentation after the
  demonstration.

11
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\.

12

• Set your path environments.
• PCC_DIRECTORY
• C\Program Files\glomosim-2.03\parsec\windowsnt-4
  .0-vc6
• PATH
• C\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 )

13

• Go to glomosim/main and do makent.bat.
• Once the make is complete, GloMoSim is ready to
  use, and lives in bin.
• Dont forget to compile the Java GUI, in
  java_gui.
• ( javac .java )

14
Demonstration of GloMoSim Installation on Windows

• We will resume the presentation after the
  demonstration.

15
Outline

• Specific examples for RPM-based Linux systems.
• Installation on a Windows NT-kernel system.
• Running a basic simulation.
• Seeing the results GloMoSim VT.

16
Running a Basic Simulation

• GloMoSim depends on its config.in file.
• Lets go through some of the basic variables in
  config.in.
• Most of them are self-explanatory, and those that
  arent 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.

17

• 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.

18

• 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

19

• 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.

21
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.
