LTE/SAE Model and its Implementation in NS 2

Expectation and requirements for future wireless communication systems continue to grow and evolve. Thus, 3GPP has considered LTE/SAE to ensure its competitiveness in the future. In LTE/SAE, one of the recurring problems is dimensioning and testing. Modeling is an effective way to solve the problem because model is easy to generate test scenarios and inexpensive in changing test configurations and running test cases. This paper is to introduce how to build an accurate enough LTE/SAE model in NS 2 so that other optimization features can be tested. This open source model includes traffic model and network model. The network model concentrates on the air interface and S1 interface. In the end of the paper, one example is given to demonstrate how to use the model.
