Dear Marcus and all,
Many thanks for the advice regarding the Hydra and ORBIT project.
Actually I’m looking for the open-source 802.11 PHY&MAC packages which
compatible with Recent GNU Radio and USRP N210/X310.
I’ve searched from internet and got some findings listed below:
Hydra PHY & MAC from University of Texas at Austin 
FTW IEEE802.11a/g/p OFDM Frame Encoder 
UWICORE m-HOP 802.11 MAC for USRP based on the FTW PHY 
*** All (1-3) only compatible with gnuradio-3.2.2 which was too many
WIME IEEE 802.11a/g/p Transceiver for GNU Radio v3.7 
*** This is a most recent package for gnuradio 3.7, but is PHY only. Are
there any MAC package which compatible with this WIME PHY?
ORBIT Project 
*** This is a huge project which can be studied. Are there any project
provide both 802.11 MAC & PHY like Hydrd did before?
