Simulation of OLSR routing protocol in OPNET Modeler environment
Potfay, Attila ; Růčka, Lukáš (referee) ; Vajsar, Pavel (advisor)
The main task of this bachelor's thesis is to simulate the routing protocol OLSR (Optimized Link State Routing Protocol) in the OPNET Modeler environment, and to realize a scenario where it is possible to model protocol functionality and properties. The processing of each simulation is divided into three main parts and they are the description of a situation, configuration and the evaluation of results. In the first scenario there is shown the functionality of the protocol, in the second simulation there are scenarios with the nodes of different movement speed, and in the third simulation the energy requirements of the protocol from the perspective of quantity of the transmitted packets are evaluated. Furthermore, in this thesis there is analyzed the way of implementing the routing protocol OLSR in the OPNET Modeler environment. The implementation structure is divided into three levels: the level of a node, a manager and the routing protocol. At these levels the process models, transitions, code blocks, variables and key codes of functions are processed. Next, there is introduced the possibility of extending the protocol. In order to extent the OLSR protocol, the work focused on supporting services quality. The functions are edited for the protocol to create logs, read out the current transfer speed from the statistics, add it to the created pool and organise writing the logs. The results are evaluated and clearly described. This work provides the theoretical basics: it deals with the primary characteristics of Mobile Ad-hoc networks (MANET), describes in detail the OLSR routing protocol and provides information about the OPNET Modeler simulation environment.
