Scheduling in OFDMA based systems

The new generation of wireless networks supports many high resource consuming services. The main problem of such networks is that the bandwidth is limited, besides to be subject to fading process, and shared among multiple users. Therefore, a combination of sophisticated transmission techniques (OFDMA…) and proper packet scheduling algorithms is necessary, in order to provide applications with suitable quality of service.
The objective of this mini-project is to build a reference model for the simulation of various scheduling algorithms using the Network Simulator (NS3). To achieve this goal, an overview of Orthogonal Frequency division multiple access is presented. Then, we discuss the Long Term Evolution cellular network and apply various scheduling algorithms on the downlink to study their behavior.
We proceed by building an LTE model in order to test the LTE downlink schedulers. The simulation results are analyzed. We compare and discuss the performance of various schedulers and our results in comparison with the theoretical performance of the schedulers.
