    This document provides instructions for a lab assignment on generating TCL scripts for network simulations using the NSG (NS2 Scenarios Generator) tool. The lab asks students to: 1. Use NSG2.1 to generate a TCL script modeling a network of 5 nodes in a ring topology with 128Kbps links having 10ms delay and using the AODV routing protocol. 2. Configure the script to send UDP packets from node 0 to node 2 at a rate of 0.02 seconds between packets, starting at 0.05 seconds and ending the transmission at 1 second. 3. Bring down the link between nodes 1 and 2 at 0.25 seconds. 4. Run

    Lab 10: Generating TCL through NSG

    Introduction
    NS2 Scenarios Generator (NSG) is a tcl script generator tool used to generate TCL Scripts
    automatically

    Objectives
    The main target of this lab to generate tcl script through NSG tool.

    Tools/Software Requirement
    NSG2.1, NS2

    Description
    NSG is a Java based tool that runs on any platform and can generate TCL Scripts for
    Wired as well as Wireless Scenarios for Network Simulator 2. The procedure to execute
    these TCL Scripts on NS-2 is same as those of manually written TCL Scripts.

    Some of the main features of NS2 Scenarios Generator (NSG) are as mentioned below:

    (1) Creating Wired and Wireless nodes just by drag and drop.
    (2) Creating Simplex and Duplex links for Wired network.
    (3) Creating Grid, Random and Chain topologies.
    (4) Creating TCP and UDP agents. Also supports TCP Tahoe, TCP Reno, TCP New-
    Reno and TCP Vegas.
    (5) Supports Ad Hoc routing protocols such as DSDV, AODV, DSR and TORA.
    (6) Supports FTP and CBR applications.
    (7) Supports node mobility.
    (8) Setting the packet size, start time of simulation, end time of simulation, transmission
    range and interference     range in case of wireless networks, etc.
    (9) Setting other network parameters such as bandwidth, etc for wireless scenarios.

    Lab Task:
    Write a tcl script that forms a network consisting of 5 nodes, numbered from 0 to 4,
    which form a ring. The links have a 128K bandwidht with 10ms delay. Set the routing
    protocol to AODV. Send UDP packets from node 0 to node 2 with the rate of 0.02
    seconds per packet. Start transmission at 0.05. Bring down the link between node 1 and
    node 2 at 0.25. Finish the transmission at 1.000. Then run nam to view the results. What
    do you see? Will packets be re-routed after the link goes down?
