Name of Package

Detail of package

Application Application package contain PingApplication class. The application can be configured to send pings with a fixed interval or to only answer to pings it receives. When the application to delivere ives a ping it sends a pong message in response. The corresponding PingAppReporter class can be used to record information about the application behaviour.

Core Core package contains java class and interface(For ex- DTNsim.java,settings.java,debug.java,DTNHost.java,NetworkInterface.java). First DTNsim class is called when run any application.

Gui Contains the classes of Graphical User Interface

Movement Movement package contain movement model class. The movement of node is based on this class. There are different movement are available(For ex-RandomWalk,RandomWayPoint etc.).we want to use any movement it is describe like this (Group.movementModel = RandomWalk).

Report Report package contains all the report classes. Report class used for the different report like (MessageDeliveryReport, contactTimeReport, ContactPerHourReport, TotalContactReport).

Routing Routing package contains all the router classes. Router class handel the message.router class decide how to message deliver to destination node.There are different routing class(Ex-MessageRouter,DirectDeliveryRouter,ActiveRouter etc.)

PING APPLICATION:

Ping_app_settings.txt File:

- This configuration file adds Ping application for all the nodes and

- a report module that counts the number of pings & pongs sent & received

# Here I Fix Scenario EndTime

Scenario.endTime = 2500

# Define new application

pingApp.type = PingApplication

pingApp.interval = 500

pingApp.destinationRange = 0,125

pingApp.pingSize = 5

pingApp.pongSize = 5

pingApp.passive = false


EM M12IT11

# Set Ping app for all nodes

Group.nrofApplications = 1

Group.application1 = pingApp

# Add report for Ping app

Report.nrofReports = 2

Report.report2 = PingAppReporter

Run Ping Application:

- If we run the ping application file with different ping.App.interval time.

- Here assume that I take all reading for Scenario.endTime = 2000.

- We get following different scenario:

Prerequisites:

1. Install Netbeans IDE 7.0.1.

2. source code of one simulator(one_1.4.1 or above)

Configuration steps :

Step 1: Install Netbeans IDE 7.0.1.

Step 2: Create Netbeans Project and Select Java Application from Java.


EM M12IT11

Step 3: Specify name of Project and unmark main class and click on finish button

.

Step 4: Copy all directories of one_1.4.1 original source into netbeans project Location

Documents >NetbeansProjects > ONE >src folder

Step: 5 Click on project name and select project properties


EM M12IT11

Step 6: Select Libraries and click on Add JAR Folder.

Step 7: Select DTNConsoleConnection.jar and ECLA.jar


EM M12IT11

Step 8: Select Run from categories manu.and Set Main class value from Browse.

Step 9: Set working directories by selecting created netbeans project path.

Step 10: Set Arguments value is “path of default_settings.txt”

Arguments = C:\Users\abhi\Documents\NetBeansProjects\ONE\src\default_settings.txt

For Batch Mode you can also set arguments like

Arguments = -b 1 C:\Users\abhi\Documents\NetBeansProjects\ONE\src\default_settings.txt

HelloRouter.java

HelloRouter.java

First we want to make Router so we have to make our own class file in Routing Package.

“hellorouter.java” file is As below

package routing;

import core.Settings;

public class HelloRouter extends ActiveRouter

{

public HelloRouter(Settings s)

{

super(s);

}

protected HelloRouter(HelloRouter r)

{

super(r);

}

@Override

public void update()

{

super.update();


EM M12IT11

if (isTransferring() || !canStartTransfer())

{

return; // can't start a new transfer

}

// Try only the messages that can be delivered to final recipient

if (exchangeDeliverableMessages() != null)

{

return; // started a transfer

}

System.out.println("HelloRouter");

}

@Override

public HelloRouter replicate()

{

return new HelloRouter(this);

}

}


EM M12IT11

Now compile this hellorouter.java which generate hellorouter.class file.

Now edit default_settings.txt file write Group.router = hellorouter

Now run Simulator in batch mode

C:\one_1.4.1\-b 1 One.bat default_settings.txt

Or We use NetBeans to make and run hellorouter

Output:-

- compile.bat

- one.bat –b 1 default_settings.txt

Explain EPIDEMIC ROUTER :

Epidemic routingis flooding-based in nature, as nodes continuously replicate and transmit messages to newly discovered contacts that do not already possess a copy of the message. In the simplest case, epidemic routing is flooding; however, more sophisticated techniques can be used to limit the number of message transfers. Epidemic routing has its roots in ensuring distributed databases remain synchronized, and many of these techniques, such as rumor mongering, can be directly applied to routing.
