Patrick Sondi Obwang University of Valenciennes patrick.sondiobwang@univ-valenciennes.fr ################################################################## This readme file will help you configure the process model that we propose for simulation purpose. This process model is a modification of the original olsr_rte process model provided in the OPNET 16.0 package. The main changes aim at providing QoS support in OLSR-based MANET. ############################################################# Download and installation instructions ############################################################# - extract the files in a temporary directory of your computer - move the header files contained in the include directory to "OPNET directory"\16.0.A\models\std\include - backup the olsr_rte.pr.m file from your OPNET original installation (see in "OPNET directory"\16.0.A\models\std\manet) - move the olsr_rte.pr.m file from process directory in the temporary directory to "OPNET directory"\16.0.A\models\std\manet ############################################################# Configuration instructions ############################################################# In addition to the OLSR protocol parameters that can be configured as described in the OPNET documentation: - You MUST specify the transmission range in the olsr_rte.function block (line 173). The default value is set to 100.0 meters for a MAC Tx power set to 0.0000323. See OPNET FAQs on www.opnet.com to learn more about fixing the range of wireless networks. The experiments we performed show that reducing the TX power causes an increase of the loss rate ... so we encourage you to use the default TX rate of OPNET and set the range to 300 meters. - You can specify the metrics that must be considered for routes computation: The default value is 0 for : bandwidth, delay, loss and willingness You can set (line 174) : 1 : for bandwidth only 2 : for delay only 3 : for loss only 4 : for willingness only - The values of the QoS metrics are refreshed according to a time interval which is stored in the window_size variable. Set it to 5.0 seconds if you use default Hello and TC intervals. Once the configuration is finished, open the olsr_rte.pr.m in the OPNET 0modeler and compile it. You are now ready to make simulation with this model of the OLSR protocol with QoS support. We are still improving the process, feel free to sending us your remarks. Note: For Linux users, the process compiler ends with warning when it detects in the source files some functions or variables that are declared but not used. Don't pay attention, just proceed! On some architectures, you need to use the advanced compiler options and choose x*** compilation instead of 32.
