Optimal cooperative cognitive relaying and spectrum access for an energy harvesting cognitive radio: Reinforcement learning approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we consider a cognitive setting under the context of cooperative communications, where the cognitive radio (CR) user is assumed to be a self-organized relay for the network. The CR user and the primary user ...
Power-optimal feedback-based random spectrum access for an energy harvesting cognitive user
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we study and analyze cognitive radio networks in which secondary users (SUs) are equipped with energy harvesting (EH) capability. We design a random spectrum sensing and access protocol for the SU that ...
On the effect of proportional fairness in energy transfer for wireless powered communication networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Wireless powered communication network (WPCN) is an emerging area of research where energy is transferred from the access point to the mobile terminals in the downlink and information is transferred in the uplink. In the ...
Optimal spectrum access for a rechargeable cognitive radio user based on energy buffer state
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests ...
Survey on energy harvesting wireless communications: Challenges and opportunities for radio resource allocation
(
Elsevier B.V.
, 2015 , Article)
Abstract Green radio communications has received a lot of attention in recent years due to its impact on telecom business, technology and environment. On the other hand, energy harvesting communication has emerged as a ...
On spectrum sharing between energy harvesting cognitive radio users and primary users
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests ...
Feasibility of air quality monitoring systems based on environmental energy harvesting
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Capillary wireless sensor networks dedicated to air quality monitoring have provided essential information on hazardous air condition, generating early warnings to prevent danger situation for human health. The arising ...
Cooperative joint power splitting and allocation approach for simultaneous energy delivery and data transfer
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose to minimize the total energy consumption cost of a simultaneous data transmission and power delivery from different sources. The receiver is designed to simultaneously process information and ...
Cooperative access schemes for efficient SWIPT transmissions in cognitive radio networks
(
IEEE
, 2015 , Conference Paper)
We investigate joint information and energy cooperative schemes in a slotted-time cognitive radio network with a primary transmitter-receiver pair and a set of secondary transmitter-receiver pairs. The primary transmitter ...
