Here is my revisions for mostly tackling the WR collisions of Lw-MAC and other mirror issues.
You can see the details in each commit. :-)
After some tests, I think Lw-MAC becomes more reliable after these adaptations.
In short, I have made these major revisions:
use CSMA for sending the first WR for collision avoidance (the bad performance of Lw-MAC is mostly due to WR collisions of multi-senders);
make WR for broadcasting like WA, since I found that it is very hard to achieve WR collision avoidance among multi senders, if WR is unicasted to its receiver.
carry the phase-lock scheme based on WA. I inserted the phase information of the receiver into its WA, thus the sender can still infer the receiver's phase once it gets the replied WA. Also, this operation excludes the effect of using CSMA for sending WRs.
