Link Level Aspects Modelling in the simulation of packet switched wireless networks

The investigation of both link and network level aspects is fundamental when a thorough analysis of mobile radio systems is required. The conventional approach, based on a complete separation between the two levels, adopted in the past for the performance evaluation of second generation systems, is not enough accurate for third generation ones, characterized by the presence of both voice and data services as well as circuit and packet switched applications. Here we describe a methodology on how to interface link and network level tools and finally show an example of application.
