Simulators for Wireless Networks: A Comparative Study Network simulation is the most predominant evaluation techniques in the area of computer Networks. The simulation models in a reliable and simple way can be developed by researchers using different simulators for evaluating the behavior and performance of protocols for different networks, simulations are a good example between cost and complexity by maintaining the accuracy of the results. This paper gives briefly survey on a performance comparison study of the different network simulators for wireless network. There are many simulators for wireless network, but among them five are the popular simulators these are: Qualnet/GlomoSim, OM-Net++, Ns-2, OPNET modeler and JSim with a real-world test bed. The information about each of the simulator abilities, their internal structure, development environment and their support for wireless network simulation has detailed discussed in this paper. This paper helps to identify one is best option among shown simulator for their best need. Finally, the paper contains survey, comparatively study and conclusion about making the suitable choice of network simulator supporting wireless network based on the numbers of surveys and papers.
