I want to control the inter packet gap ie. time interval between transmission of two packets. For this I have disabled CCA and am setting the SIFS and AIFS to the desired inter packet gap that I want ie. 100 microseconds. However I observe that no matter whatever value of SIFS or AIFS I set, I get the inter packet gap equal to acktimeout value which is set. I also tried using cbr quese and did set the cbrperiod to 100 microseconds, but even that did not work.

Has any one any suggestions as to how I can achieve this?? and why is setting SIFS time not working??
