How to Implement 5G Network in ns2
To implement the 5G network in ns2 (Network Simulator 2), we cannot easily establish it because ns2 has a inherent restrictions and it is mainly configured for older networking standards such as 2G, 3G and some 4G functionalities. These simulator doesn’t help the advanced features of 5G includes mmWave communication, massive MIMO, or network slicing.
Yet, we can recreate particular perspectives of 5G network by expanding the ns2 with personalize modules or by aiming on certain components that is enhanced throughput, decreased latency or improved mobility support which are vital properties of 5G networks. In the below, we offer the implementation process of 5G network using ns2:
Step-by-Step Implementation:
Step 1: Understanding the Limitations of ns2
Before continuing, it’s vital to recognize that ns2 lacks straight help for several 5G-specific features. We may need to utilize ns3 that has latest support for advanced wireless communication features containing some 5G features. Follow the below to process the 5G network and specific components.
Step 2: Create a Basic Tcl Script
Begin by replicating a high-speed, low-latency wireless network that are vital components of 5G. it includes setting up nodes with high bandwidth and low delay links.
Example Tcl Script for Enhanced Mobile Broadband (eMBB)
# Create a simulator object
set ns [new Simulator]
# Define the topography object
set topo [new Topography]
$topo load_flatgrid 1000 1000
# Create the General Operations Director (GOD) for wireless simulations
create-god 5 # Number of nodes in the network
# Configure node settings for a high-speed wireless network (simulating 5G characteristics)
$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 \
-channelType Channel/WirelessChannel \
-topoInstance $topo \
-agentTrace ON \
-routerTrace ON \
-macTrace ON \
-movementTrace OFF
# Open trace and NAM files for recording the simulation
set tracefile [open 5g_out.tr w]
$ns trace-all $tracefile
set namfile [open 5g_out.nam w]
$ns namtrace-all-wireless $namfile 1000 1000
# Define a finish procedure to close files and end the simulation
proc finish {} {
global ns tracefile namfile
$ns flush-trace
close $tracefile
close $namfile
exec nam 5g_out.nam &
exit 0
}
# Create high-speed wireless nodes
for {set i 0} {$i < 5} {incr i} {
set node_($i) [$ns node]
}
# Set initial positions for the nodes
$node_(0) set X_ 100.0
$node_(0) set Y_ 200.0
$node_(0) set Z_ 0.0
$node_(1) set X_ 300.0
$node_(1) set Y_ 300.0
$node_(1) set Z_ 0.0
$node_(2) set X_ 500.0
$node_(2) set Y_ 400.0
$node_(2) set Z_ 0.0
$node_(3) set X_ 700.0
$node_(3) set Y_ 500.0
$node_(3) set Z_ 0.0
$node_(4) set X_ 900.0
$node_(4) set Y_ 600.0
$node_(4) set Z_ 0.0
# Define traffic to simulate high-speed communication (eMBB)
# CBR (Constant Bit Rate) traffic from node 0 to node 4
set udp [new Agent/UDP]
$ns attach-agent $node_(0) $udp
set null [new Agent/Null]
$ns attach-agent $node_(4) $null
$ns connect $udp $null
set cbr [new Application/Traffic/CBR]
$cbr attach-agent $udp
$cbr set packetSize_ 1500 # Larger packets to simulate high data rates
$cbr set rate_ 100Mb # Simulate high data rate
$cbr start 1.0
# Schedule the end of the simulation
$ns at 20.0 “finish”
# Run the simulation
$ns run
Step 3: Run the Tcl Script
Save your Tcl script with a .tcl extension (e.g., 5g_simulation.tcl). Then, execute the script by following the below command:
ns 5g_simulation.tcl
This will generate a trace file (5g_out.tr) and a NAM file (5g_out.nam).
Step 4: Visualize the 5G Network
Use the NAM tool to visualize the network:
nam 5g_out.nam
This will open the NAM window where you can monitor the high-speed communication amongst the nodes.
Customizing the Script for 5G Features
- Higher Data Rates: Model the high data rate characteristic of 5G by modifying the rate parameter in the CBR traffic.
- Low Latency: Indicate the low-latency communication predicted in 5G networks by altering the link delays in the simulation.
- Mobility Support: Optimize mobility models by dynamically informing node locations to mimic the high mobility backed by 5G.
Step 5: Consider ns-3 for Advanced 5G Features
For a more realistic recreation of 5G networks as well as support for technologies like mmWave, massive MIMO, and network slicing, Take into account to use ns3 which is a more modern network simulator that modules particularly generated for 5G.
In conclusion, we offered the details to help you get started with a basic 5G network implementation using ns2 and it contains the simulation of Tcl Script for Enhanced Mobile Broadband (eMBB). Furthermore, we will clarify the any concern about this manual.
