Energy Efficient Resource Allocation in Machine-to-Machine Communications with Multiple Access and Energy Harvesting for IoT
(2018-02-01)
© 2014 IEEE. This paper studies energy efficient resource allocation for a machine-to-machine enabled cellular network with nonlinear energy harvesting, especially focusing on two different multiple access strategies, ...
Optimal Fairness-Aware Time and Power Allocation in Wireless Powered Communication Networks
(Institute of Electrical and Electronics Engineers, 2018-02-19)
In this paper, we consider the sum α-fair utility maximization problem for joint downlink (DL) and uplink (UL) transmissions of a wireless powered communication network via time and power allocation. In the DL, the users ...
On the Optimality of Power Allocation for NOMA Downlinks with Individual QoS Constraints
(Institute of Electrical and Electronics Engineers, 2017-03-30)
This letter investigates a power allocation problem in a downlink single-input single-output non-orthogonal multiple access (NOMA) system. Our goal is to maximize the sum rate of users subject to minimum user rate requirements. ...
Resource Allocation for D2D Communications Underlaying a NOMA-Based Cellular Network
(Institute of Electrical and Electronics Engineers, 2017-10-03)
This letter investigates the power control and channel assignment problem in device-to-device (D2D) communications underlaying a non-orthogonal multiple access (NOMA) cellular network. With the successive interference ...
A Caching Strategy Towards Maximal D2D Assisted Offloading Gain
(Institute of Electrical and Electronics Engineers (IEEE), 2019-08-08)
Cache placement in two-tier hetnets with limited storage capacity: Cache or buffer?
(Institute of Electrical and Electronics Engineers, 2018-06-12)
In this paper, we aim to minimize the average file transmission delay via bandwidth allocation and cache placement in two-tier heterogeneous networks with limited storage capacity, which consists of cache capacity and ...
On Consideration of Content Preference and Sharing Willingness in D2D Assisted Offloading
(Institute of Electrical and Electronics Engineers, 2017-03-09)
© 1983-2012 IEEE. Device-to-device (D2D) assisted offloading heavily depends on the participation of human users. The content preference and sharing willingness of human users are two crucial factors in the D2D assisted ...
