How to Implement dsdv protocol in ns2

To implement the Destination-Sequenced Distance-Vector (DSDV) protocol in Network Simulator 2 (ns2) requires a few steps. NS2 already contains a simple implementation of DSDV, so you can adjust or utilize this implementation as a beginning point. In the below, we demonstrate the implementation procedure of DSDV using ns2:

Step-by-Step Implementation:

  1. Set Up NS2 Environment:
  • Make certain to install the ns2 on your computer. You can download and install it from NS2 official sources.
  1. Locate DSDV Files:
  • The DSDV protocol is executed in NS2 by default. You can discover the relevant files in the following directory:
    • ns-allinone-2.xx/ns-2.xx/ where xx denotes the version of NS2 you are using.
  • The main files for DSDV implementation are:
    • dsdv.cc: This file has the main implementation of the DSDV protocol.
    • dsdv.h: This file includes the header information for the DSDV protocol.
    • dsdv.tcl: This file comprises the TCL script to recreate DSDV in NS2.
  1. Modify DSDV Files (if needed):
  • You have to alter the dsdv.cc and dsdv.h files, to customize the DSDV protocol (such as attach new mechanisms, vary parameters). Make certain to recompile NS2 after making alterations:

cd ns-allinone-2.xx/ns-2.xx/

make clean

make

  1. Create TCL Script for Simulation:
  • Replicate the network using DSDV protocol by generating a TCL script. Below is a basic sample of a TCL script that configures a basic wireless network using DSDV:

# Define the number of nodes

set val(nn)           10

set val(x)            500

set val(y)            500

set val(stop)         10.0

# Define the network topology

set ns [new Simulator]

set tracefile [open out.tr w]

$ns trace-all $tracefile

# Define the network nodes

for {set i 0} {$i < $val(nn)} {incr i} {

set node_($i) [$ns node]

$node_($i) random-motion 0

}

# Setup DSDV Routing Protocol

$ns node-config -adhocRouting DSDV \

-llType LL \

-macType Mac/802_11 \

-ifqType Queue/DropTail/PriQueue \

-ifqLen 50 \

-antType Antenna/OmniAntenna \

-propType Propagation/TwoRayGround \

-phyType Phy/WirelessPhy \

-topoInstance $topo \

-agentTrace ON \

-routerTrace ON \

-macTrace OFF \

-movementTrace OFF

# Define the traffic (CBR) in the network

set udp [new Agent/UDP]

set null [new Agent/Null]

$ns attach-agent $node_(0) $udp

$ns attach-agent $node_(1) $null

set cbr [new Application/Traffic/CBR]

$cbr set packetSize_ 1000

$cbr set interval_ 0.005

$cbr attach-agent $udp

$ns connect $udp $null

$ns at 0.1 “$cbr start”

# Set node positions (optional)

$node_(0) set X_ 0.0

$node_(0) set Y_ 0.0

$node_(0) set Z_ 0.0

$node_(1) set X_ 100.0

$node_(1) set Y_ 0.0

$node_(1) set Z_ 0.0

# Run the simulation

$ns at $val(stop) “stop”

$ns run

  1. Run the Simulation:
  • Save your TCL script (e.g., dsdv_example.tcl) and use ns2 to execute the script:

ns dsdv_example.tcl

  1. Analyze the Output:
  • Ns2 will create trace files (like out.tr) that includes detailed information about the simulation once the process is complete. You can evaluate these files to learn the action of the DSDV protocol in your network.
  1. Visualize the Simulation:
  • Visualize the simulation results by using Network Animator (NAM):

nam out.nam
