Due to the complex nature of computer and telecommunication networks, it is often difficult to predict the impact of different parameters on system performance especially when deploying wireless networks. Computer simulation has become a popular methodology for performance study of computer and telecommunication networks. This popularity results from the availability of various sophisticated and powerful simulation software packages, and also because of the flexibility in model construction and validation offered by simulation. While various network simulators exist for building a variety of network models, choosing a good network simulator is very important in modeling and performance analysis of wireless networks. A good simulator is one that is easy to use; more flexible in model development, modification and validation; and incorporates appropriate analysis of simulation output data, pseudorandom number generators, and statistical accuracy of the simulation results. OMNeT++ is becoming one of the most popular network simulators because it has all the features of a good simulator. This chapter aims to provide a tutorial on OMNeT++ focusing on modeling and performance study of the IEEE 802.11g wireless network.
