A simulation model of DYMO for ad hoc routing in OMNeT++

Mobile Ad Hoc Networks (MANETs) have evolved in the last years into standards in the communication world. By definition, they do not need any network infrastructure to facilitate communication between participating nodes. Therefore, they are dealing with new challenges in the context of ad hoc routing. In this paper, we present our new implementation of the ad hoc routing protocol Dynamic MANET On Demand (DYMO) for the popular discrete event simulation environment OMNeT++. DYMO offers adaptation to changing network topology and determines unicast routes between nodes within the network on demand. Based on the developed model, we performed several simulation experiments to analyze the performance of DYMO with respect to changing network size and traffic conditions. The implementation of DYMO and the results of the simulation experiments are described in this paper.
