A real wireless network’s efficiency and behaviour can be tested using simulation systems without the need for field experiments and prototype creation. The simulation solutions give the opportunity to grow to a desired wireless network channel allocation schemes, network architectures, etc. The simulation software development approach becomes a very critical issue influencing the resulting network model and efficiency, due to the complexity of real wireless networks. A big challenge for wireless network simulation is the discovery of a way to tackle the actual actions of the network and not just speed up execution time using parallel machines. The simulation model and environment structure affect the performance of simulated wireless networks, and for this reason the design and development of such systems is studied thoroughly. Modern simulation tools provide network engineers with the opportunity to develop and test wireless communication systems at low cost very quickly. There are three major simulation techniques (Chaturvedi, A., et al. 2001): discrete event simulation (DES), system dynamics, and multi-agents. The most widely known simulation tools are based on the DES concept and use various model architectures to implement. A more accurate and reliable simulation environment can be developed with the help of efficient model architectures (Chaturvedi, A., et al. 2001; Liu, W., et al. 1996; Zeng, X., et al. 1998; Bajaj, L., et al. 1999; Kelly, O.E., e...
