Purpose Prevent malicious use of EDCF in IBSS May, 2003 Matthew Sherman, AT&T Labs

May, 2003 Background Existing DCF solutions restrict user parameters selections so that reasonable behavior results in most situations Existing EDCF solutions allow that EDCF parameters may be set to any value for a station – even if not reasonable Need to protect the user from himself (and each other Matthew Sherman, AT&T Labs

May, 2003 Background (2) One malicious user could bring down entire network by choosing unreasonable setting Should encourage station designs to not permit users to adjust EDCF parameters Force to receive setting from QAP Further safeguards may be desired in AP Infers that should not be able to use EDCF in IBSS or BSS since need QAP Matthew Sherman, AT&T Labs

Market Impact Reliable use of medium is key to 802.11 success May, 2003 Market Impact Reliable use of medium is key to 802.11 success While non-802.11 complaint use of license free bands is allowed, should not be encouraged Eg. Use of EDCF in BSS Vendors need to police themselves to ensure malicious use of their designs is not allowed Otherwise if malicious use of medium becomes common will limit growth of 802.11 for many applications Matthew Sherman, AT&T Labs

May, 2003 Motion To adopt the changes identified in document #03/WWWr0 into the current TGe Draft Matthew Sherman, AT&T Labs
