The Development of A Realistic Simulation Framework with OMNeT++

It is necessary to use simulation tools in the study of wireless network. The object-oriented modular discrete event network simulator, OMNeT++, can not only afford many network simulation but has strong GUI support and an embeddable simulation kernel. In this paper, a novel realistic simulation framework (called R-simulator) is pro- posed based on OMNeT++. R-Simulator has realistic GUI and strong ¿message¿ management while considers the node mobility and protocol stack. R-Simulator is also time- saving and memory-efficient. The design process of R- Simulator and its advantage on realistically displaying the network are detailedly described. Based on R-Simulator, we give examples to show its favorable performance.peer-reviewe
