name isFranciscoCárdenas, I'm a Spanish engineerandI
write thisemailto find asolution to myproblem withMadwifi.
am currentlyworking ona researchfor
energy savingin the 802.11 standardand for thatI have madea platform with twoPCIcard (DWL-G520) withatheroschipset. I
also useMadwifi as driver.
platformconsists of the following: a card will act asAPand the other asstation. This stationmust send aconstantnumber of framesto the access point(eg, sample temperature).The access pointcan requesta smaller amount ofsamples bythebeaconframeto the station. To sendfewer frames, I do not under thefrecuency of sending of packets in the estation. What we reallydo islower
thetransmission power (txpower) to have packet loss andsave energyin the transmission (by IOCTL calls). The problemis thatwhen I loseabout
20%of packetsthe cardquicklybecomes unstable andstarts to have100%of
but takestime to stabilize(20 -30 seconds).
wish I hada 50%packet lossto
increasethe margin of myenergy
questionis if thisproblem (going from 20%to 100% loss
packets) is due to Madwifiand if
aparameter that can bechanged.
funny thingis that whenthere is a100% lossand tries tosend
frames, the access point isreceiving
packets.Probablythe card is notreceivingacks.
you help me?
would appreciategreatly.Thank you very muchfor everything.
