How to Start Distance Vector Routing Projects Using NS2

To create a Distance Vector Routing project using NS2 (Network Simulator 2), you should follow for this step by step procedures for this implementation:

Steps to Start Distance Vector Routing Projects Using NS2

Step 1: Setup NS2 Environment

  1. Install NS2:
    • Download and install NS2 from NS2 Official Website or use precompiled packages.
    • Enable the all dependencies are installed for sample Tcl/Tk, OTcl, and NAM.
    • Validate the installation using:

ns -version

  1. Familiarize with NS2:
    • Analysis the essential architecture for NS2 scripts written in Tcl.
    • Examine the samples are offers in the ns-allinone-2.x/examples/ directory.

Step 2: Understand Distance Vector Routing

  • Distance Vector Routing Protocols (e.g., RIP):
    • Routers can modify the distance vectors by neighbours periodically.
    • Every router has measured the minimum path for the destination terms on the received vectors.
    • Execute the protocol logic as per your project necessary.

Step 3: Design the Network Topology

  1. Describe the network by nodes such as routers in the replication script:

set ns [new Simulator]

# Create nodes

set n1 [$ns node]

set n2 [$ns node]

set n3 [$ns node]

# Create links

$ns duplex-link $n1 $n2 1Mb 10ms DropTail

$ns duplex-link $n2 $n3 1Mb 10ms DropTail

  1. Signify the routers and interconnections utilized their nodes and connection.

Step 4: Implement Distance Vector Routing

  1. Modify Routing Logic:
    • NS2 used the static routing through default. Execute the dynamic distance vector routing through generating or alter the routing agents.
    • Used the modify routing logic in C++ for agent development or Tcl for simpler logic.
  2. Sample Implementation:
    • Build a new routing agent through encompass the previous Agent class in NS2.
    • Bring up-to-date routing tables are dynamically according to the distance vectors.

Sample in Tcl for basic setup:

Agent/DistanceVector instproc recv {pkt} {

# Logic for processing incoming packets and updating the distance table

}

  1. Routing Updates:
    • Replicate the periodic modify for routing tables.
    • Bring up-to-date the replication for script to reflect the route changes dynamically.

Step 5: Simulation and Testing

  1. Define Traffic Flow:
    • Enhance the UDP or TCP congestion we replicate a real-world network activity.
    • Example:

set udp [new Agent/UDP]

$ns attach-agent $n1 $udp

set sink [new Agent/Null]

$ns attach-agent $n3 $sink

$ns connect $udp $sink

set cbr [new Application/Traffic/CBR]

$cbr attach-agent $udp

$cbr set packetSize_ 512

$cbr set interval_ 0.05

$ns at 1.0 “$cbr start”

  1. Run the Simulation:
    • Save the Tcl script such as distance_vector.tcl.
    • Estimate using:

ns distance_vector.tcl

  1. Analyze Results:
    • Used the NAM (Network Animator) for visualization.
    • Checked the suggestion files for performance parameter for sample packet delivery ratio, delay.

Step 6: Extend the Project

  1. Add advanced features like:
    • They divide the horizon by poison reverse.
    • The route invalidation for the timers.
    • Adaptive routing according to the network conditions.
  2. Associates the performance through other routing protocols such as Link-State Routing.
