Performance Analysis of Power Control and Cell Association in Heterogeneous Cellular Networks

Abstract

The research investigation focuses on modeling and mitigation of interference in Heterogeneous networks (HetNets). Stochastic geometry-based analytical tools are used to develop tractable mathematical models. The idea is to abstract the spatial distribution of nodes and users by points of suitable point processes. Developed mathematical models are used to identify the effects of various parameters and network configurations on the performance of cellular networks. In particular, the aims of this research project are to: (i) develop analytical tools to comprehensively capture practical conditions of HetNets, including the spatial distribution of nodes and different environmental conditions (fading, shadowing, and path loss); (ii) develop new power control schemes for HetNet uplink transmission; (iii) develop simple cell association policies for HetNets; and (iv) investigate the impact of practical limitations in cell association policies on the performance of HetNets. Overall, the research findings will pave the way to the design of new energy-efficient and spectrally-efficient high-throughput cellular systems.
