Simulation of mobile networks using discrete event system specification theory

The fourth generation (4G) of mobile telecommunication technology provides ultra-band internet access for mobile devices such as smartphones, tablets, and laptops. One of the challenges in the Long Term Evolution (LTE) 4G networks is the low data rate for cell-edge users as well as coverage gaps. In this paper, we define and evaluate models for analysis of performance of mobile networks architectures defined by 3GPP. We used the Discrete-Event System Specification (DEVS) formalism to model the mobile networks and implement the framework. The proposed model implements the deployment layout of the Base Station (BS) cellular antennas, and it manages the distribution and movement of the User Equipment (UE) devices. The model calculates the Propagation for each BS, as well as the path-loss in the links between BSs and the UEs in the range. It also computes the power received by the BS and the UE in each link. These results will be used in the design of models for Coordinated Multipoint approach in delivering faster data.
