Re: [wirelesslan] hye..

so i'm late to reply ur email..Actually once the STA decides to look for other AP, the probing process starts.The STA starts sending out probe requests and then processes received probe responses.The time involved in this probing process is called probe delay.This delay contributes the largest delay in the handoff process.
I'm sure that can reduce the probe delay..My lecturer advice me to focus the simulation on the handoff process first and then gain the result from the simulation..do u have any reference that related to my project?

Could you explain what you mean by 'probe delay'?

The device could send out probe frames and build a list of available
APs that it could roam to while it is still associated with an AP. It
could periodicially update this list and sort it from 'best' to
'worst' depending on some criteria that you choose - signal strength
is the most choice but not the only one. When the time comes to roam,
it doesn't need to look for a suitable AP but uses this list to
associate. Would this approach reduce this 'probe delay'?
