Wireless Network Simulation Using OPNET IT Guru Academic Edition. Part 6 View Results.

6. View Results:

After running simulation for all scenarios we can now view results to compare between the scenarios by clicking on the show results tool on the tool bar, a view results window will appear showing all the selected statistics, selecting the overloaded statistics for all scenarios to be in the same graph with different colors, changing the view to the average type so the graph be in a curve way, finally we can view the graph in a separate window with full information and legend.

• The HTTP page response time: from this graph comparing our four scenarios we understand that the response time of a HTTP page decreases as the data rate increases. 

• TCP Delay: as we do before the average TCP Delay graph shows that the average TCP delay decreases as the data rate increases.

• Wireless LAN Data Dropped: for all the scenarios this graph shows that the Wireless Data dropped tends to be zero.

• Wireless LAN delay: this graph shows that the delay of the wireless LAN decreases as the data rate increases.

• Wireless LAN Load: the average load of the network will remain the same as the application supported and the number of the workstations stills the same.

• Wireless LAN Media Access Delay: this graph shows that the media access delay will be decreased as the data rate increased.

• Wireless LAN Throughput: even if this graph is not seen the average throughput will be the same as the average load if the data dropped tend to zero (Load Request = Throughput Success + Data Dropped Failure), so here the graph tells us the same fact the throughput remains the same for all scenarios and looks like the load graph.
