Performance Evaluation of Self Backhauled Small Cell Networks

We compare the performance of HetNets with Self Backhauled Small Cells (SBSCs) relative to those with Wired Backhaul based Small Cells (WBSCs). The comparisons are made for a variety of SBSC based HetNets (1) when the HetNets employ Omni antennas at the SBSCs and Uniform PF at the Macro, (ii) with Directional antennas at the SBSCs and Uniform PF at the Macro, (iii) with Directional antennas at the SBSCs and Weighted PF at the Macro, and (iv) with Directional antennas at the SBSCs and QoS-aware PF at the Macro. The study catalogs our learning experiences with SBSC Het-Nets, leading the reader through the sequence of enhancements made to improve the performance of SBSC HetNets relative to WBSC HetNets.
