摘要：Implementation of new generation wireless networks is a challenging task that requires detail network planning and protocol level simulation in order to foresee possible problems and save investment and operation costs. Existing simulation platforms are very complex, expensive and vendor specific. It requires special knowledge for modifying and adopting protocols. This article presents Authors’ designed mathematical model and model based software that allows universal packet level simulation of different wireless protocols. Software provides graphical user interface that allows to describe simulated protocol, control simulation, analyze time flow diagrams and graphical QoS results for different access and connectivity network nodes. In addition to article presents mobile WiMAX handover simulation example and provides QoS calculation results that prove the importance of network simulation prior to implementing real network in order to be able to foresee possible bottlenecks and plan required overheads.
