Use Riverbed Modeler and show draw and results

1-Create two new scenarios as duplicates of the DCF_PCF scenario. Name the first new scenario DCF_allPCF and the second new scenario DCF_twoPCF . In DCF_allPCF , enable the PCF attribute in all eight nodes: node_1 through node_8. (Note: Do not include node_0 in any of your attribute editing.) In DCF_twoPCF , disable the PCF attribute in node_3 and node_5 (this will leave only node_1 and node_7 with PCF enabled).

2-For all scenarios, select Media Access Delay statistics. Rerun the simulation and generate the graph that compares the Media Access Delay statistics for all scenarios. Analyze the graph, explaining the effect of PCF, fragmentation, and number of PCF nodes on Media Access Delay?

3-Based on the definition of the statistic Load in Question 1 (i); explain why with PCF enabled scenario, the load is lower than DCF (used without PCF)?

4-Analyze the graphs that compare the Delay & Throughput of the four scenarios in Question 1 (i). What are the effects of utilizing PCF and fragmentation on these two statistics?

5-Create two new scenarios as duplicates of the DCF_PCF scenario. Name the first new scenario DCF_allPCF and the second new scenario DCF_twoPCF . In DCF_allPCF , enable the PCF attribute in all eight nodes: node_1 through node_8. (Note: Do not include node_0 in any of your attribute editing.) In DCF_twoPCF , disable the PCF attribute in node_3 and node_5 (this will leave only node_1 and node_7 with PCF enabled).

6-Generate the graphs for the Delay, Load , and Throughput statistics, and explain how the number of PCF nodes might affect the performance of the wireless network.
