A discrete event based simulation environment for enhanced UMTS 3rd generation networks

This paper presents a new system level simulator that has been developed to evaluate E-UMTS (Enhanced Universal Mobile Telecommunication Systems) 3G Networks. The article describes how the simulator supports different mobility, propagation, and traffic generation models and how this simulation framework can be used to evaluate new protocols, algorithms, or resource management mechanisms. Specific models and performance details for a sample scenario of a business city center are also provided.
