6. CONCLUSIONS AND FUTURE WORK The paper provided an overview of the current status of the LTE advanced technologies and the approaches in modeling and simulation of these networks. We proposed a model of 4G LTE networks based on a formal theoretical approach that can be used for M&S applications, which uses mathematical techniques for discrete-event M&S. In this re- search, we used the Discrete-Event Systems specification formalism (DEVS), and the CD++ software to implement the model. A few chosen simulation results have been presented graphically using charts and the observed facts have been discussed. The charts were in compliance with the latest 3GPP Technical Report [13]. This work is in the early stages and the long term goal is to use the current simulation platform as the basis for modeling distributed approaches of CoMP processing in 3G and 4G LTE networks. 7.
