Analysis of K-Tier Uplink Cellular Networks With Ambient RF Energy Harvesting
We use stochastic geometry to develop a comprehensive modeling framework for K-tier uplink cellular networks with RF energy harvesting from the concurrent cellular transmissions. In the considered system model, channel inversion power control is used and cellular users are equipped with energy storage units. We also use tools from queueing theory, namely, Markov chain analysis, to model the lev...
متن کاملEnergy-efficient downlink resource management in self-organized OFDMA-based two-tier femtocell networks
Femtocell is a novel technology that is used for escalating indoor coverage as well as the capacity of traditional cellular networks. However, interference is the limiting factor for performance improvement due to co-channel deployment between macrocells and femtocells. The traditional network planning is not feasible because of the random deployment of femtocells. Therefore, self-organization ...
متن کاملDownlink Interference Mitigation Scheme for Two-tier OFDMA Cellular Networks
In a two-tier cellular network, macrocells and femtocells coexist. Since femtocells use low transmission power and share network resources with macrocells, they are considered as one of the promising solutions to highly congested network environments. However, since femtocells are deployed in a selforganized manner without cell-planning, they cause severe downlink interference to macro users. T...
متن کاملImproving Energy Efficiency of Two-tier OFDMA Femtocell Networks with Distributed Power Control
This paper addresses how to improve the energy efficiency of two-tier OFDMA femtocell networks using power control. Firstly, the energy efficiencies of two typical power control methods are analyzed, including fixed power setting (FPS) and minimum power consumption (MPC) methods. Then a distributed maximum energy efficiency (MEE) method is proposed. Each macrocell and femtocell dynamically adju...
متن کاملA Velocity-Aware Handover Trigger in Two-Tier Heterogeneous Networks
The unexpected change in user equipment (UE) velocity is recognized as the primary explanation for poor handover quality. In order to resolve this issue, while limiting ping-pong (PP) events we carefully and dynamically optimized handover parameters for each UE unit according to its velocity and the coverage area of the access point (AP). In order to recognize any variations in velocity, we app...
