Generalized SIR Analysis for Stochastic Heterogeneous Wireless Networks: Theory and Applications
Chun-Hung Liu, Zhu-Kuan Yang, Di-Chun Liang
This paper provides an analytically tractable framework of investigating the statistical properties of the signal-to-interference power ratio (SIR) with a general distribution in a…
Fundamentals of the Downlink Green Coverage and Energy Efficiency in Heterogeneous Networks
Chun-Hung Liu, Kok Leong Fong
This paper studies the proposed green (energy-efficient) coverage probability, link and network energy efficiencies in the downlink of a heterogeneous cellular network (HetNet) con…
Traffic Management for Heterogeneous Networks with Opportunistic Unlicensed Spectrum Sharing
Chun-Hung Liu, Hong-Cheng Tsai
This paper studies how to maximize the per-user-based throughput in an M-tier heterogeneous wireless network (HetNet) by optimally managing traffic flows between the access points…
Minimum Size of Feedback Vertex Sets of Planar Graphs of Girth at least Five
Tom Kelly, Chun-Hung Liu
A feedback vertex set of a graph is a subset of vertices intersecting all cycles. We provide tight upper bounds on the size of a minimum feedback vertex set in planar graphs of gir…
Size of the Largest Induced Forest in Subcubic Graphs of Girth at least Four and Five
Tom Kelly, Chun-Hung Liu
In this paper, we address the maximum number of vertices of induced forests in subcubic graphs with girth at least four or five. We provide a unified approach to prove that every 2…
On the Limits of Coexisting Coverage and Capacity in Multi-RAT Heterogeneous Networks
Chun-Hung Liu, Hong-Cheng Tsai
This paper devises a general modeling and analyzing framework for a heterogeneous wireless network (HetNet) in which several wireless subnetworks coexist and use multiple radio acc…
