Opportunistic Wireless Energy Harvesting in Cognitive Radio Networks
TL;DR: In this paper, a stochastic geometry model was proposed to maximize the secondary network throughput under the given outage-probability constraints in the two coexisting networks, which reveals key insights to the optimal network design.

Opportunistic Wireless Energy Harvesting in Cognitive Radio Networks
TL;DR: A stochastic-geometry model in which PTs and STs are distributed as independent homogeneous Poisson point processes (HPPPs) and communicate with their intended receivers at fixed distances is considered, which reveals key insights to the optimal network design.
Journal ArticleDOI
Coverage and Economy of Cellular Networks with Many Base Stations
Seunghyun Lee,Kaibin Huang +1 more
TL;DR: In this article, the authors adopt a stochastic-geometry model of the downlink cellular network and analyze the mobile outage probability, which is shown to diminish inversely with the increasing ratio between the BS and mobile densities.
Journal ArticleDOI
Cognitive Wireless Powered Network: Spectrum Sharing Models and Throughput Maximization
Seunghyun Lee,Rui Zhang +1 more
TL;DR: In this paper, a cognitive radio-enabled secondary wireless powered communication network (WPCN) under spectrum sharing with the primary wireless communication system is considered, where a cognitive WPCN, consisting of one single H-AP with constant power supply and distributed wireless powered users, shares the same spectrum for its DL WET and UL WIT with an existing primary communication link.

TL;DR: A stochastic-geometry model of the downlink cellular network is adopted and the outage probability is shown to diminish inversely with the increasing ratio between the BS and mobile densities, and the optimal BS density is proved to be proportional to the square root of the mobile density.
