An interesting question: Association phase in Ad-hoc?

Recommended Posts

There is no AP to control the association process. Only “probe request”/”probe response”/’beacon”/ATIM/authentication frames are used.

What happens if there is no association phase?

Why does not a station in the ad-hoc network control the association process?

From the CWAP study guide freely available from the CWNP website:

 

With an IBSS, the first active Ad Hoc station establishes the RF channel

and starts sending beacons. Other Ad Hoc stations can join the network

after receiving a beacon and accepting the IBSS parameters (e.g., beacon

interval) found in the beacon frame. All stations that join the IBSS

participate in the sending of beacons. Each station schedules itself to

send a beacon a very short random delay interval after each Target

Beacon Transmission Time (TBTT). TBTTs are the exact points in time

that each access point has scheduled a beacon to be sent onto the wireless

medium. TBTTs are based on a zero reference time and spaced according

to the beacon interval. Each station that receives a beacon during its

delay cancels sending its beacon this time and schedules one for a new

random delay interval after the next TBTT.
