Compiling the program:
----------------------
1) Unzip uxg140230.zip using the command 'unzip uxg140230.zip'. This will create a directory 'uxg140230'.

2) Enter directory 'uxg140230/'. This is the WORKING directory of the program. This directory contains following subdirectories or files
   "bin  execute1.sh  execute2.sh  files  HBGP.txt  lib  logs  Makefile  README  src"

3) Run 'make' command. This will compile the code and create following executables in 'bin/' directory.
   "brouter  controller  irouter"

Running the program:
--------------------
1) All the scenario scripts or executubles should be run from the WORKING directory (i.e uxg140230/).   

2) ****IMPORTANT****
   For the executables to run you should set the environment variable LD_LIBRARY_PATH to 'lib/'
   This can be done in 2 ways
   a) Use 'export LD_LIBRARY_PATH=lib/' in your current shell OR
   b) [Recommended] Let 'export LD_LIBRARY_PATH=lib/' be the first command in each of your scenario scripts. 
      Sample scenario files 'execute1.sh' and 'execute2.sh' are present in 'uxg140230/'

3) To run an executable from WORKING directory (uxg140230/) you should use th command './bin/<exec_name>'
   e.g. ./bin/irouter 01 03 01 02 02
   
4) All the ouput files will be saved in 'files/' directory (i.e uxg140230/files/).

5) Please clear the contents of 'files/' directory before running a scenario script. Otherwise, it may result in incorrect output.
   
6) *IMPORTANT*. Do not delete any directory.
