Introduction

 

G-ORS is a MIMO RA algorithm that provably learns as fast as it is possible the best stream mode and MCS level for transmission.

 

Wireless Device Driver: Ath9k
Test Kernel Version: Linux-3.11.6
Test Operation System: Ubuntu12.04
Supported Standard: IEEE 802.11n
Supported Operation Mode: single-stream(SS), double-stream(DS)


Our device driver developed based on backports package release 3.11.6-1.

In particular, the main code is ~/net/mac80211/rc80211_ors_ht.c.

 

Download G-ORS

Instruction

 

1. Download and extract the driver source code.

 

# tar -xvf ORS_backports-3.11.6-1.tar.bz2

2. Compile the G-ORS source code.
(linux-headers needs to be installed before you compile the code.)

 

# make defconfig-ath9k
# make menuconfig

# sudo make install

3. Insert G-ORS module

 

# sudo rmmod ath9k ath9k_common ath9k_hw ath mac80211 cfg80211 compat
# sudo modprobe ath9k
