Hi, I am currently experimenting to determine and measure the overhead/throughput decrease that WPA Personal - TKIP encryption causes to wireless networks. the test bed I used is a Linksys AP along with 2 very similar laptops (1 wired-100mbps ethernet and 1 wireless - 802.11g). I use the software called LanTraffic on both laptops. On the wireless laptop, I generate packets sizes ranging from 1024KB-8192KB and measuring throughput with a 1ms inter packet delay. I then user encryption - tkip: a 10 letter passphrase and repeat the above tests and then keep increasing the passphrase length by 10 every cycle.
I tried it using 54Mbps at first and then decreased it to 6Mbps and get different numbers but again no signifcant reduction.
The weird part is that I do not get any significant reduction in the throughput. Is this normal? Does anybody know why this is going on? or what I can change to get more accurate results?
Thank you in advance
