🌐 Networks Trace File Analysis

This project was created for studying CSMA/CD and 802.11 (CSMA/CD) Protocols

🗂 Project Structure

The project is organized into two main folders, each corresponding to a type of network:

1. 🌐 Wired LAN

This folder contains files related to wired LAN using CSMA/CD protocols.

• Files:

  • wiredlan.tcl: The original TCL script.
  • wiredlanincreased7.tcl and wiredlanincreased.tcl: Scripts with additional network load.

• AWK Scripts:

  • 📄 packetdeliveryratiowired.awk and 📄 throughputwired.awk: These scripts generate data outputs and formatted text for graphs.

• Outputs:

  • 📄 test.txt: Output used for creating graphs.
  • 📊 Various .png files generated from the outputs using makegraph.sh.

2. 📡 Wireless LAN

This folder contains files related to wireless LAN in Ad Hoc mode using 802.11 protocols.

• Files:

  • wirelessLan.tcl: The original NS2 script.
  • wirelessLan5nodes.tcl: Script showcasing additional load with 5 nodes.
  • 10node.tcl: Script showcasing 10 nodes.

• AWK Scripts:

  • 📄 packetdeliveryratio.awk, 📄 throughput.awk, and 📄 throughputavg.awk: These scripts output necessary information for wireless networks.

• Outputs:

  • 📊 Various .txt files created to be used by makegraph.sh to generate .png graphs.

Each script is located in the appropriate folder for its specific network setting (wireless/wired).

I hope you find this project and the experiments conducted to observe network behavior informative and useful.

Thank you.

🛠 How to Run

1. Create and run your .tcl script:

   ns filename.tcl

2. Two files will be created:

   • 📄 .nam (GUI)
   • 📄 .tr (trace)

3. Run the .awk scripts on the .tr file:

   gawk -f throughputavg.awk wirelessLan.tr

   

4. Create graphs:

   • Edit makegraph.sh with the correct files, then run:

   gnuplot makegraph.sh

🔔 Note: Before running the .sh and gnuplot to create graphs, ensure the AWK scripts format the information into a .txt file.
