I have 2 IEEE 802.11e network scenarios and i need to know the difference between them. One is a network where we assume stations transmit only one traffic type, say 4 stations and one transmits video, another transmits voice, another data, like that and the second scenario is where each station transmits all 3 or 4 traffic types. Question is:
1. How is throughput analysed/affected in 2nd scenario considering each STA has multiple EDCAF.
2. How do i analyse transmission probability on the channel?
Using AP controller for WLAN or network monitoring system you can see the traffic flow . Also create VLAN by segmentation etc.
Or maybe you can use multiple instances of iPerf to mimic different traffic types. Suppose that in Scenario 2 you create an iPerf instance in a station using UDP and certain bandwidth; another instance using TCP at another bandwidth and so on for as many Access Categories/Traffic Types as you want. This way you get the aggregate throughput from each iPerf instance and compare it to those achieved in Scenario 1 using the same tools (but instead of instances you run a single iPerf process in each station, of course).
Using OPNET Modeller, configure an ESS or Adhoc WLAN and inject http traffic as well as configure the parameters. When you execute the simulation, you should be able to analyze the throughput metrics
