How to implement 6G Networks in ns2

To implement the 6G networks within NS2 (Network Simulator 2) is a difficult task because the simulation tool NS2 is mainly created for preceding generations of network technologies, and it is lacks direct help for furthered characteristics are predictable in 6G networks, like terahertz communication, AI-driven network management, massive MIMO, and ultra-low latency communication. But, we can emulate some features of 6G by customizing NS2 to simulate the higher data rates, lower latency, and more sophisticated routing protocols. We have leading experts who work on implementation of 6G networks within NS2 tool contact us to get outstanding results.

Given below is a step-by-step approaches on how we can theoretically mimic the particular features of 6G networks in NS2:

Step-by-Step Implementations:

  1. Understand the Scope:
  • The 6G Networks are predictable to aid the terahertz communication, AI-driven network management, massive machine-type communications (mMTC), ultra-reliable low-latency communication (URLLC), and etc.
  • The simulation tool NS2 does not support these directly, however we can mimic a few of these concepts by changing metrics related to the routing protocols, latency, and data rate.
  1. Set Up the NS2 Environment:
  • Make sure NS2 is installed on the system with support for the wireless simulations.
  • Acquaint ourselves including writing TCL scripts, as NS2 emulations are controlled through TCL.
  1. Define the Network Topology:
  • We make the nodes that denote devices in the 6G network. It can be user equipment (UE), base stations, and core network elements.

# Define the simulator

set ns [new Simulator]

# Create a trace file for analysis

set tracefile [open out.tr w]

$ns trace-all $tracefile

# Create a NAM file for animation

set namfile [open out.nam w]

$ns namtrace-all-wireless $namfile 10

# Set up the wireless network parameters (customized for 6G)

set opt(chan)   Channel/WirelessChannel      ;# Channel type

set opt(prop)   Propagation/TwoRayGround     ;# Radio-propagation model

set opt(netif)  Phy/WirelessPhy              ;# Network interface type

set opt(mac)    Mac/802_11                   ;# MAC type

set opt(ifq)    Queue/DropTail/PriQueue      ;# Interface queue type

set opt(ll)     LL                           ;# Link layer type

set opt(ant)    Antenna/OmniAntenna          ;# Antenna model

set opt(ifqlen) 100                          ;# Max packet in ifq

set opt(x)      1500                         ;# X dimension of the topography

set opt(y)      1500                         ;# Y dimension of the topography

set opt(adhocRouting) AODV                   ;# Ad hoc routing protocol

# Create a topography object

create-god 50

# Configure the nodes (representing 6G devices)

$ns node-config -adhocRouting $opt(adhocRouting) \

-ifqLen $opt(ifqlen) \

-antType $opt(ant) \

# Create nodes: Base Station, User Equipment (UE), and Core Network

set bs1 [$ns node]   ;# Base Station 1

set ue1 [$ns node]   ;# User Equipment 1

set ue2 [$ns node]   ;# User Equipment 2

set core1 [$ns node] ;# Core Network Node 1

# Set initial positions for the nodes

$bs1 set X_ 750.0

$bs1 set Y_ 750.0

$bs1 set Z_ 0.0

$ue1 set X_ 500.0

$ue1 set Y_ 500.0

$ue1 set Z_ 0.0

$ue2 set X_ 1000.0

$ue2 set Y_ 1000.0

$ue2 set Z_ 0.0

$core1 set X_ 750.0

$core1 set Y_ 750.0

$core1 set Z_ 0.0

  1. Customize for Higher Data Rates and Lower Latency:
  • To mimic the higher data rates and lower latency that are features of 6G, by modifying the link parameters and changing the routing protocols.

# Create duplex links with high data rates and low latency to simulate 6G characteristics

$ns duplex-link $bs1 $core1 100Gb 1ms DropTail

$ns duplex-link $ue1 $bs1 10Gb 1ms DropTail

$ns duplex-link $ue2 $bs1 10Gb 1ms DropTail

  1. Simulate Communication Between Nodes:
  • We set up the communication among the user equipment (UE) and the base station (BS), and among the base station and the core network.

# User Equipment 1 sends data to the Core Network via Base Station 1

set tcp_ue1 [new Agent/TCP]

$ns attach-agent $ue1 $tcp_ue1

set tcp_core1 [new Agent/TCPSink]

$ns attach-agent $core1 $tcp_core1

$ns connect $tcp_ue1 $tcp_core1

# Start sending traffic from UE1 to Core Network

set ftp1 [new Application/FTP]

$ftp1 attach-agent $tcp_ue1

$ns at 2.0 “$ftp1 start”

# User Equipment 2 sends data to the Core Network via Base Station 1

set tcp_ue2 [new Agent/TCP]

$ns attach-agent $ue2 $tcp_ue2

set tcp_core1_2 [new Agent/TCPSink]

$ns attach-agent $core1 $tcp_core1_2

$ns connect $tcp_ue2 $tcp_core1_2

# Start sending traffic from UE2 to Core Network

set ftp2 [new Application/FTP]

$ftp2 attach-agent $tcp_ue2

$ns at 2.5 “$ftp2 start”

  1. Implement Advanced Routing or AI-driven Decisions:
  • We can execute the furthered routing protocols or emulate AI-driven decisions by tailoring the routing or by appending the decision-making logic.

# Example of adding a simple decision-making process (abstract AI)

proc ai_routing_decision {src dst} {

global ns

# Simulate an AI decision to choose the best path

puts “AI is making a routing decision between $src and $dst…”

# Here you could add logic to select the best path or adjust parameters

}

# Schedule AI-driven routing decisions

$ns at 1.5 “ai_routing_decision $ue1 $core1”

$ns at 1.5 “ai_routing_decision $ue2 $core1”

  1. Run the Simulation:
  • Describe while the simulation would end and then we run it. The terminate procedure will close the trace files and introduce the NAM for visualization.

# Define the finish procedure

proc finish {} {

global ns tracefile namfile

$ns flush-trace

close $tracefile

close $namfile

exec nam out.nam &

exit 0

}

# Schedule the finish procedure at 10 seconds

$ns at 10.0 “finish”

# Run the simulation

$ns run

  1. Analyse the Results:
  • We can use the trace file (out.tr) to examine the packet delivery, delays, throughput, and other performance metrics.
  • We open the NAM file (out.nam) to visualize the network operations and then monitor the interactions among the nodes.
  1. Customize and Extend:
  • We can tailor the simulation by:
    • We can appending more UEs, base stations, and core network nodes.
    • To mimicking furthered 6G concepts like edge computing, ultra-dense networks, or terahertz communication.
    • We executing more sophisticated AI-driven network management or resource allocation methods.

Example Summary:

This instance sets up a simple 6G network simulation in the simulation tool NS2, that concentrating on the higher data rates, lower latency, and AI-driven decision-making. This extracts few 6G concepts into the NS2 environment, while complete 6G simulation could be essential more advanced tools or extensions to the NS2.

Advanced Considerations:

  • For factual 6G simulations, deliberate the incorporating NS2 including other tools or emerging custom modules that can well manage 6G features such as terahertz communication, massive MIMO, or advanced AI algorithms.
  • We investigate the co-simulation methods in which NS2 models the network though other tools manage particular 6G technologies.

Debugging and Optimization:

  • We can use the trace-all command to debug the emulation and estimate the packet flows.
  • To enhance the emulation by refining the routing decisions, modifying link parameters, and fine-tuning network properties.

We performed a structured procedure on 6G network, employing the simulation tool ns2 for its implementation and analysis. If you require, further comprehensive details we will be provided.
