Hi,
This might be somewhat off the topic here, but I would like to know if any
way to capture the access point usage in TCP/IP layer.
If it could be done by any way we can build a [distributed or central
database] system so that each registered mobile user can automatically get
all available local access points, instead of looking for available ap on
the web The accesspoint owner just need to report his accesspoint
information to a central service which is doing delivery to mobile users,
instead of posting his own access point on the website.
I am doing a school project at Columbia Universit. My plan is to develop
we-based monitor system of an access point usage by mobile users so that
the
accesspoint owner could get the information that who has used the Internet
through my accesspoint and how many packets were transmitted throught my
accesspoint.
The furture development in my mind is when an accesspoint (or this wireless
network) reconizes an registered mobile user (maybe by his mac address)
then
this accesspoint delivers usefull information from a central database (
e.g., available accesspoints nearby, local map, local restaurant,
bookstores..., dependents on the registered mobile user)
However, I have tried Ethereal running on my desktop with filter "ether
host
[accesspoint mac address]" but never got any packets [except some broadcast
messages] when I used my another laptop with my accesspoint. I could get my
laptop usage with filter "ether host [wlan pcmcia mac address]" from the
beginning of the arp request.
Thank you in advance for your help.
