BonnMotion - A mobile scenario Generator Tool

BonnMotion is a tool that generates scenario for ns2, ns3, qualnet, etc. This will comfortably work with Linux. And in windows, there could be some bugs.

Please refer the documentation here: http://sys.cs.uos.de/bonnmotion/doc/BonnMotion_Docu.pdf

To use this tool for ns2, here are the steps.
Step1 : Download the BonnMotion tool from this website
Step 2: Unzip it to home folder (/home/pradeepkumar in my case)
step 3: Here are the commands to install
$] unzip -d bonnmotion-2.1.3.zip
$] cd bonnmotion-2.1.3/
$] ./install 
The above command will install, if any packages are missing for dependencies, please install it.

$] Once installed, copy the bonnmotion-2.1.3/bin/bm file to /usr/bin/ for running it anywhere. if not go to bin folder using the command given below

$] cd bonnmotion-2.1.3/bin/

To run BonnMotion
$bonnmotion-2.1.3/bin] ./bm -hm 
(this will list all the models)

$bonnmotion-2.1.3/bin] ./bm -hm RandomWaypoint
Will display all the parameters for RandomWaypoint like number of nodes, x, y, random seed, etc.

Assuming RandomWaypoint is the model

$bonnmotion-2.1.3/bin] ./bm -f scenario RandomWaypoint -n 10 -x 500 -y 500
The above command will create a file called scenario with 10 number of nodes with x and y as 500x500)

$bonnmotion-2.1.3/bin]  ./bm NSFile -f scenario
This will create two files called scenario.ns_movements, scenario.ns_params


The above two files can be used inside tcl script for ns2 using the source command

source scenario.ns_params
source scenario.ns_movements



(NB: Please note that the above two files represents nodes like $node_(0), etc and $ns_ as simulator object, either you change these variables within your tcl file or edit the above two files.  Also scenario.ns_params file shows the stop script as set val(duration) 600.0, but most of the tcl scripts may have val(stop), so change it to val(duration) in all cases) 


The same will be applied to other simulators also, refer the documentation given in the beginning of the slide.

Some screenshots for you.:

Download the sample files here: put all the files in a single folder and run the tcl file using
$] ns ex.tcl

Link State Routing in NS3 - Wired Network

Link state routing in ns3

There are two varieties of protocols that deals with wired networks namely distance vector routing and link state routing, 

As per the wikipedia, Distance-vector routing protocols, which work by having each node share its routing table with its neighbours, in a link-state protocol the only information passed between nodes is connectivity related. Link-state algorithms are sometimes characterized informally as each router, "telling the world about its neighbors.

This exercise can be one of the lab exercises of many universities in India. There are many more exercises to follow. If one understand this video, they can able to simulate any network design and run it successfully in ns3.

In this blog post, I am not going to explain the concepts of link state routing, but will explain how to configure the nodes to use link state routing in ns3. 

Please find the video for the source code explanation and compilation in ns3 on link state routing protocol

Here is the step to run the LSR and compile it to get the details.

Scenario is

How to Run this file in ns3

This file LinkStateRouting.cc have to be stored in ns-3.29/scratch folder

open a terminal 

$ cd ns-allinone-3.29/ns-3.29/

$ ./waf --run scratch/LinkStaterouting

To run network animation

Open a new terminal 

$] cd ns-allinone-3.29/netanim-3.108/

$] ./NetAnim

The output is shown like this
