MiRA

Introduction

MiRA is a novel MIMO RA scheme that zigzags between intra- and inter-mode rate options. There is some detailed information of MiRA source code as follows:

Basic Algorithm:"MIMO Rate Adaptation in 802.11n Wireless Networks", MOBICOM, 2010See the paper here.

Supported Standard:IEEE 802.11a/g/n

Supported Operation Mode:single-stream(SS), double-stream(DS), triple-stream(TS)

Wireless Driver:Ath9k

Kernel Version:Linux-3.11.6

Test Operation System:Ubuntu12.10

Latest Version:MiRA-3.11.6-rev1.0

Build

• Step1:Download and extract the driver source code.
  # wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.11.6/backports-3.11.6-1.tar.bz2
# tar -xvf backports-3.11.6-1.tar.bz2
• Step2:Download and patch the MiRA source code.
  # tar -zxvf MiRA-3.11.6-rev1.0.tar.gz -C backports-3.11.6-1/
# cd backports-3.11.6-1
# patch -p1 < MiRA-3.11.6-rev1.0.patch

• Step3:Compile the MiRA source code.
  NOTE:linux-headers needs to be installed before you compile the code.
  # make defconfig-ath9k
# make menuconfig
