OPTIMIZING DATA RATE OVER HYBRID FSO/MMWAVE LINK IN HIGH ALTITUDE C-RAN MOBILE NETWORK ARHITECTURE

Abstract

In this thesis, a C-RAN architecture where a hybrid transmission technology FSO/mmWave channel is used to transport the fronthaul between the RRHs and the cloud of BBUs. The reason behind this assumption is to control the hand over between FSO and mmWave channels in case of failure as a result of weather conditions. To achieve a maximum sum data rate in this C-RAN architecture, we optimize hand over process using ILP programming. Simulations show the potential of a hybrid FSO/mmWave channel in counteracting the effects of weather conditions. The model can be modified to consider the case where both FSO and mmWave channels are used concurrently to achieve a certain data rate for a particular case.
