An Open Source Product-Oriented LTE Network Simulator Based on Ns-3

In this paper, the authors present a new simulation module for ns-3 aimed at the simulation of LTE networks. This module has been designed with a product-oriented perspective in order to allow LTE equipment manufacturers to test RRM/SON algorithms in a simulation environment before they are deployed in the field. First, they describe the design of the simulation module, highlighting its novel aspects. Subsequently, they discuss the testing methodology that they adopted to validate its output. Finally, they present some experimental result to assess its performance in terms of execution time and memory usage.
