Hi all, I'm doing a project on power saving for adhoc network, using ATIM window. However, the transmission of beacons at each beacon interval makes TSF timers unstable in IBSS environment. Then, our first task is to stabilize the TSF timer. We do this by letting only the faster stations compete for transmitting beacon at beacon intervals. At those intervals, the stations with slower TSF timers need not send beacon. I would like to ask where in ath9k we could change the code to disable or enable beacon transmission (i.e., turn on\off beacon transmission) as wanted? As far as I found from ath9k, ath9k_hw_dissable_interrupts defined in mac.c stops sending a beacon and ath9k_hw_set_interrupts restarts transmitting beacon as normal. Is it true in ath9k? If we cannot change beacon transmission in ath9k, could we stop hardware's beaconing and use software to describe the desired beacon transmission mechanism (as our own way) ? Any comment or suggestion would be appreciated.
