Tutorial Level: BEGINNER

Next Tutorial: How to run wifi_comm

Downloading and installing olsrd 0.6.0

WifiComm requires olsrd to work, so before you actualy download and install WifiComm you will download and install olsrd.

Go to http://www.olsr.org/?q=olsrd-0.6.0 and download olsrd 0.6.0. WifiComm might work with newer versions however that has never been tested.

Extract the olsrd 0.6.0 folder into your Desktop, open a new terminal window and run the following commands:

cd Desktop/olsrd-0.6.0
sudo make install

Now you need to install txtinfo and httpinfo:

cd lib/txtinfo
sudo make install
cd ..
cd httpinfo
sudo make install

Finally you'll need to change the default port on olsrd which is 2006 to 8080. To do that open the file olsrd.conf:

sudo gedit /etc/olsrd.conf

Find the following line:

#PlParam "port" 

Add a new line so that it looks like this:

#PlParam "port"
PlParam "port" "8080"

Save the file and close it.

You can test olsrd by running the following command:

sudo olsrd -i ra0

Your interface might be something like ra0 or wlan0. Also, don't forget you must be root to run olsrd hence the sudo.

Downloading and installing wifi_comm

Start by going to a directory that is on your ROS_PACKAGE_PATH where you'll want to install wifi_comm.

You'll start by downloading multimaster_experimental since wifi_comm needs foreign_relay to work.

svn co https://code.ros.org/svn/ros/stacks/multimaster_experimental/trunk multimaster_experimental

Next you'll dowload lse_communication which is the stack that holds the wifi_comm package.

svn co http://isr-uc-ros-pkg.googlecode.com/svn/stacks/lse_communication/trunk/ lse_communication

Finally all you have to do is rosmake wifi_comm:

rosmake wifi_comm

And that's it! Congratulations on downloading and installing wifi_comm!

You are now ready to proceed to the next tutorial, How to run wifi_comm!
