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 (<Alt> <PrtSc>) and paste it into your lab document.

Task 2 – Run the Discrete Event Simulation
* Use <Alt><PrtSc> 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 <Alt><PtrSc> to capture this DES Graphs window and paste it into your lab document.

* What is the average throughput for the wireless LAN?
-------------------------------------------------

* When does the largest delay in the Wireless LAN occur?
-------------------------------------------------

* 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 <Alt><PrtSc> to this DES Graphs window (as shown below) and paste it into your lab document.

* When (in seconds) does the Group A WAP traffic dip begin? _____________________

* When (in seconds) does the Group A WAP traffic dip end? _____________________

* What server traffic accounts for the peak in Group B 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 B Group / Throughput (bits/sec). Change the presentation style to Stacked Statistics. Use <Alt><PrtSc> to this DES Graphs window (as shown below) and paste it into...
