I’m a student from the University Miguel Hernandez (www.umh.es). I’m
trying to understand how to communicate a GNU Radio process (802.11a PHY
transmitter) with a Click Modular Router process (802.11a MAC-state
machine). I’ve been reading for a while the mailing list, and some
papers related with this issue, but I still have some unsolved
I explain: Click modular router process has to read/write packets
from/to a TCP UNIX socket. The GNU Radio process should read this
packets, move the packet through a flow graph (modulation OFDM,…) and
transmit it to the air.
The Click work side is done (communicates with a TCP socket) but I
haven’t started the GNU Radio side yet.
As Eric B. says in this post
) a good way to do this is using Unix domain sockets to glue both
processes. Therefore, I’ve had the next idea: to communicate two
different processes using a socket handler in Python(only in the GNU
Radio side) in the next way:
1st: create a block [socket_handler.py] - which reads/writes socket data and converts this data into "GNU Radio messages" 2nd: Prepend the previous block to the PHY flow-graph (as the first element of my PHY block) and adapt the messages received from [socket_handler] as a payload for the following PHY blocks.
I’ve read another posts, but before start programming I’d like to have a
clear idea of what I want to do and whether it is correct or I’m missing
something. Any other proposal to do this will be welcomed.
PS: The 802.11a transmitter version I’m using comes from the FTW project
on CGRAN and Click projects comes from Hydra project.
