Hello to all,

Well i m working on the project having the system in which their is
one PC which will act as a
server. Then there sre some wireless devices. In-between, there are
access points, so there is wired connection between server to Access
points and again wireless connection betwen access points to devices.
Now i wanted to command from the sever to the wireless devices and
vice-versa
The device is having dynamic IP allocation.
As i don't know much about the networking, doing the networking
project first time, i have been studing the documents available on
net. According to that what i understand is that the TCP/IP is used
for wired communication between server to access point and there
should be some wireless communication between access point and device
like WLAN protocol. Can we use the socket programming to acheive TCP
protocol???
But still the full idea of protocol is not yet cleared. Can anyone
please clarify the idea how the communication is going to happen using
TCP/IP.

Thanks in advance...........

Nutty.

I think you are confusing protocol layers, which is perhaps the source
of your question.

In the wired part of the link, the protocols used are TCP/IP over
Ethernet. When the TCP/IP packets, encpasulated in the Ethernet frame,
reach the wireless access point, the Ethernet part of the journey ends.
At this point, the TCP/IP packets, unchanged, are extracted from the
Ethernet frame and instead sent over an IEEE 802.11 protocol. So, the
WLAN protocol replaces the Ethernet protocol in the wireless link, but
does not affect the TCP and IP layers at all. Or at least, it doesn't
need to, unless you are doing something more customized.

Sorry. Rereading what I wrote, that's confusing. There should be one
TCP/IP packet in each Ethernet frame.

Hi,

You need to think about the size of your system. You have a server,
access points, and a mobile node. You need to decide how far the
mobile node will travel. You need to decide if the acess points are
relatively close together, where they can be call connected by
machinery that you control, or if you are trying to build a system
where the mobile node is expected to connect to any arbitrary access
point, and from there, will be able to reach the server.
