Hi all,
I have two USRPs. I would like to implement some functions (RTS and NAV)
in 802.11 MAC. Actually, I want to use RTS to control one of the nodes when to
send out packets. When the node recieves the RTS, it should set up its NAV.
Hence, the node will not send any packets out during the NAV. I read the codes
in the BBN project and still have no idea how to implement the functions that I
need. Could anyone please give me some hints or examples to implement the
funcations?
RTS
Node1 ----------> Node2 (after
receives RTS, set up NAV)
data
Node1 <---------- Node2 (after
NAV, send out data)
Should I run both bbn_80211b_tx.py and bbn80211b_rx.py on each USRP? For
example, I have Node1 and Node2. Node1 run bbn_80211b_tx.py to send out RTS
and run bbn80211b_rx.py to receive data that sends from Node2. Node2 run
bbn_80211b_tx.py to send out data and run bbn80211b_rx.py to receive RTS that
sends from Node1 and then set up NAV.
I don't consider the strict timing issues of MAC at this moment. I only want to
implement the functions.
Thank you,
Jane
