Abstract: In this paper, we present a multisystem wireless simulator based on a semi-dynamic principle with sequential executions to assess the performance of a large-scale network with tens to hundreds of base stations and WLAN hot spots. The semi-dynamic simulator achieves a fast computation time by exploiting the advantages of both analytical modelling and event driven simulation. The simulator architecture is briefly illustrated and the theoretical background is highlighted as well as the implemented Radio Resource Management (RRM) and Joint-RRM (JRRM) algorithms. The simulator is well suited to guide heterogeneous radio network deployment and design. Simulation results are provided to illustrate the practical use of the simulator as well as its efficiency.
