SEC450 Wireless Roaming iLab Report
Task 1—Configure DES Global and Node Statistics
Under Node Statistics, select Data Traffic Received (bits/sec) and Throughput (bits/sec). Capture a copy of the completed Choose Results dialog ( ) and paste it into your lab document.
Task 2—Run the Discrete Event Simulation
Use to capture a copy of the Simulation Execution dialog shown below and paste it into your lab document.
Task 3—Analyze the WLAN and WAP DES Results
Under Global Statistics for the Wireless LAN, select Delay and Throughput. Make sure that the presentation is set to Stacked Statistics. Use to capture this DES Graphs window and paste it into your lab document.
What is the average Throughput for the Wireless LAN?
.
The average throughput is about 700,000 bits/sec for the Wireless LAN.
When does the largest delay in the Wireless LAN occur?
It looks like the largest delay starts from the beginning for about 0.7 seconds.
Under Object Statistics, select Group A WAP / Data Traffic Recvd (bits/sec) and Group B WAP / Data Traffic Recvd (bits/sec). Change the presentation style to Overlaid Statistics. Use to this DES Graphs window (as shown below) and paste it into your lab document.
When does the Group A WAP traffic dip begin? it starts in about 25s in
When does the Group A WAP traffic dip end? it ends in about 1min and 5s
What server traffic accounts for the peak in Group B traffic? Both A and B Server’s traffic accounts for the peak in Group B WAP Traffic.
Task 4—Analyze the Group A and Group B Server Throughput
Under Object Statistics, select Server for A Group / Throughput (bits/sec) and Server for B Group / Throughput (bits/sec). Change the presentation style to Stacked Statistics. Use to this DES Graphs window (as shown below) and paste it into your lab document.
Explain the drop in Throughput for the Server
