How to Start Wireless Communication Projects Using OMNeT++

To start Wireless Communication projects using OMNeT++ which encompasses to replicate the wireless networks, to experiment the communication protocols, examining performance, and then executing mobility. OMNeT++ environment requires integrating with some frameworks such as INET, SimuLTE, or Veins are offers the tools for modeling and estimate the wireless communication systems efficiently. Below is a structured technique to start the Wireless Communication Projects using OMNeT++.

Steps to Start Wireless Communication Projects in OMNeT++

1. Install OMNeT++

• Download: Go to the official OMNeT++ webpage to download the new version of it on the system.
• Install: Based on the OS, we should adhere to the installation instructions.
• Verify Installation: Make sure that OMNeT++ IDE is effectively installed.

2. Install Required Frameworks

Wireless communication projects have need of frameworks, which offer wireless protocols, mobility models, and signal propagation capabilities.

Recommended Frameworks:

1. INET Framework:
   • This frameworks provides wireless protocols such as Wi-Fi, ZigBee, routing, and mobility models.
   • We can download it from the official website of INET.
2. SimuLTE (optional):
   • It used for LTE and 5G wireless interaction.
   • Visit SimuLTE’s repository to download it.
3. Veins (optional):
   • This framework frequently used in vehicular wireless networks.
   • It may combine SUMO for mobility simulation.

Installation Steps:

1. Initially, we download the framework like INET.
2. In the OMNeT++ workspace, we can obtain it.
3. In OMNeT++ environment to import the project using File > Import > Existing Projects.
4. To form the framework in OMNeT++.

3. Define the Wireless Communication Scenario

Decide on the kind of wireless communication system replicating:

• Wi-Fi Networks: It helps to design the coverage, interference, and traffic.
• Ad Hoc Networks: Mimic infrastructure-less interaction in these networks.
• IoT: It supports to design lightweight communication protocols for connected devices.
• Cellular Networks: Make use of LTE/5G frameworks for base stations and mobile devices in the cellular networks.

4. Define the Network Topology

Describe the network including wireless nodes, base stations, and connections with the help of .ned files.

Example .ned File for Wi-Fi Network:

network WiFiNetwork

{

submodules:

accessPoint: AccessPoint;     // Wi-Fi access point

mobileNode[0..4]: MobileNode; // 5 mobile nodes

connections allowunconnected:

mobileNode[*].wlan <–> accessPoint.wlan; // Wireless links

}

Example .ned File for Ad Hoc Network:

network AdHocNetwork

{

submodules:

node[0..9]: WirelessNode; // 10 ad hoc nodes

connections:

node[*].wlan <–> node[*].wlan; // Wireless communication

}

5. Implement Wireless Communication Logic

• Application Layer:
  • We can utilize the built-in applications of INET such as UdpBasicApp or TcpApp in this layer.
  • For certain traffic patterns, we should execute the custom apps.
• Routing Protocols:
  • We need to utilize the routing protocols such as AODV, DSR, or custom ad hoc routing protocols.

Example C++ Code for Packet Exchange:

void WirelessNode::sendPacket()

{

Packet *pkt = new Packet(“DataPacket”);

send(pkt, “wlan$o”);

}

void WirelessNode::receivePacket(Packet *pkt)

{

EV << “Received packet: ” << pkt->getName() << endl;

delete pkt;

}

6. Configure Wireless Parameters

In the omnetpp.ini file, configure the wireless-specific metrics with transmission power, frequency, and bandwidth.

Example Wi-Fi Configuration:

network = WiFiNetwork

sim-time-limit = 200s

*.accessPoint.wlan[*].radio.transmitter.power = 20mW

*.mobileNode[*].wlan[*].radio.transmitter.power = 10mW

*.mobileNode[*].app[0].typename = “UdpBasicApp”

*.mobileNode[*].app[0].destAddress = “accessPoint”

*.mobileNode[*].app[0].messageLength = 1024

*.mobileNode[*].app[0].sendInterval = uniform(0.1s, 0.5s)

Example LTE Configuration:

network = LTEWirelessNetwork

sim-time-limit = 100s

*.eNodeB[*].transmissionPower = 30dBm

*.UE[*].mobility.speed = uniform(5, 15) # Mobile node speed

*.UE[*].app[0].typename = “VideoStreamingApp”

7. Simulate Mobility

Mobility is crucial within wireless communication. We can utilize mobility models of INET or combine SUMO for vehicular mobility.

Example Mobility Configuration:

*.mobileNode[*].mobilityType = “RandomWaypointMobility”

*.mobileNode[*].mobility.speed = uniform(1, 5)   # Speed between 1 and 5 m/s

*.mobileNode[*].mobility.bounds = “0,0,500,500”  # Simulation area

8. Run and Debug the Simulation

• Run Simulation:
  • We should run the simulation in .ini file with the support of OMNeT++ IDE.
• Debugging:
  • Observe packet flow and then detect issues for debugging to utilize the tools of logs and visualizations.
• Visualization:
  • Monitor the node mobility and wireless interaction for visualization.

9. Analyze Results

• Metrics to Evaluate: We estimate the performance indicators like:
  • Throughput, latency, and jitter.
  • Packet delivery ratio.
  • Signal strength and interference.
• Tools for Analysis:
  • In .sca and .vec files, we can be utilized the built-in tools of OMNeT++ for analysis.
  • For advanced visualization, we need to transfer data into external tools like Python, MATLAB, or Excel.

10. Extend the Project

                  Energy Efficiency:

• • Execute the energy-saving techniques for mobile devices.

Scalability:

• • Maximize the volume of nodes and then monitor the performance of scalability.

Advanced Protocols:

• • Replicate the advanced protocols such as 5G NR or Wi-Fi 6.

Security:

• • We can design the secure interaction also replicate the attacks like jamming for network security.

QoS:

• • For real-world applications such as VoIP or video streaming to enhance the service quality.

Example Wireless Communication Use Cases

Wi-Fi Network Performance:

• • Examine the network performance like throughput and coverage within compact environments.

IoT Communication:

• • Mimic lightweight protocols such as MQTT or CoAP for IoT communication.

Ad Hoc Network Routing:

• • In this network, we can experiment the routing protocols like AODV or DSDV.

5G Wireless Communications:
