For the highly techincal:
I am doing a little research on how the 802.11 a,b,g, etc. standards are implemented. These wireless standards are able to exists in 'ad-hoc' or infrasture mode, right? Within ad-hoc mode, how does 'client a' know that 'client b' is still there? i.e. how do the clients know a client, that they've set up communications with already, is still online and hasn't been forced off the network? Is there a periodic "i'm here" packet sent by the clients to identify they're still around? Is it done in a better more efficent way?
Does anyone have any insight?
Thanks ahead of time.
