In this paper, we study the outage probability minimizing problem in a two-hop cooperative
relay network. To reduce outage probability, existing studies propose many schemes for …

This paper studies an unmanned aerial vehicle (UAV)-assisted wireless powered sensor
network (WPSN), where sensor nodes of multiple types can simultaneously harvest radio …

The potential of the Non-Orthogonal Multiple Access (NOMA) approach for wireless
communications in the fifth generation (5G) and beyond can not be underestimated. This is …

In this paper, we consider a novel cooperative underlay cognitive radio network based on
non-orthogonal multiple access (CR-NOMA) with adaptive relay selection and power …

This paper investigates a cooperative non-orthogonal multiple access (C-NOMA) system,
where the NOMA and buffer-aided cooperative transmission modes between the users are …

Abstract Intelligent Transportation Systems are witnessing a paradigm shift with the
integration of Cooperative Vehicular Networks. The transformations in Intelligent …

In this paper, we study the sum-rate maximization problem for relay cognitive network based
on decoding and forwarding (DF), where the primary network is implemented with the …

With the progress of the eras and the development of science and technology, the
requirements of device-to-device (D2D) connectivity increased rapidly. As one important …

Relay-enabled cooperative communication has been a hot topic in the area of the Internet of
Things (IoT), for its help in providing important solutions to resource limitations in IoT …

In non‐orthogonal multiple access (NOMA) systems, it may not be advisable to send the
superimposed signal of all users to individual users with retransmission requirements during …
