Simulation of the Ford–Fulkerson Algorithm Using Omnet++
Journal Title: Acta Technica Napocensis- Electronica-Telecomunicatii (Electronics and Telecommunications) - Year 2012, Vol 53, Issue 2
Abstract
This paper presents a contribution to the OMNeT++ 4.1 simulator in C++ by integrating our own implementation of the FF - Ford-Fulkerson multipath routing algorithm. In order to validate it, an eight-node testbed works with dynamic requested and released flows on each link, updated every second. Four simple scenarios were proposed, considering all possible combinations of fixed and/or random variation laws. Additionally, the path search algorithm BFS - Breadth First Search was implemented too. This software package running under Fedora Core gets the input data from three files called Nodes, Connections and Params. This mechanism provides the interworking between the C++-based FF simulator and the Java-based application in Intellij IDEA 10.5, used as traffic variation simulator. The graphical representations of the occupied, the requested and, respectively, the released flows are obtained by aggregating the contributions of all flows from the paths for any given source–destination pair.
