Lab Quiz Mobile Networks Lab 7 [email protected] Scenarios • Create two scenarios: – The first one is the HubLAN scenario – The second is the HubAndSwitchLAN scenario • Connect all nodes with10BaseT • Compare the performance of the four scenarios in terms of delay, throughput, and collision count. Parameters • Packet size= 1) 512 bytes 2) 1500 bytes • Packet Inter-arrival time=exp(0.001) Questions • Compare the load and throughput of both scenarios. Find %age increase/decrease of throughput for 2nd scenario. • Compare the Delay observed by packets in both scenarios. Find %age increase/decrease of the end-end delay in 1st scenario. • Compare the collision count of centralHub (Scenario1), Hub1Hub4(Scenario2). Find %age increase/decrease of collision count of centralHub(scenario1 HubLAN). Analysis Questions • Explain why adding a switch makes the network perform better in terms of throughput and delay. • Analyze the collision count of the Switch in Scenario2 and compare the result with that of HUB. Explain the difference. • Observe the difference in throughput(bits/sec) for different packet sizes. Explain your answer.
