As an important application of the fifth generation (5G) mobile communication systems,
Internet of Things (IoT) has attracted worldwide research interests. Since most of the …

Energy efficiency (EE) is a key issue in energy-constrained wireless networks because of
the energy scarcity. In this paper, we present the robust energy-efficient optimization design …

This paper considers a cooperative cognitive radio network with two primary users (PUs),
and two secondary users (SUs) that enables two-way communications of primary, and …

In this paper, we investigate the performance of energy harvesting two-way relay systems in
the presence of transceiver hardware impairments (HIs). In order to improve the reliability of …

We investigate the resource allocation and relay selection in a two-hop relay-assisted multi-
user orthogonal frequency division multiple access (OFDMA) network, where the end-nodes …

In this paper, we investigate the performance of a hybrid receiver-based simultaneous
wireless information and power transfer (SWIPT) two-way relay network over Nakagami-m …

In this paper, an energy efficiency maximization (EEM) optimization problem for the multi-
user multi-carrier energy-constrained amplify-and-forward (AF) multi-relay network is …

In this paper, we investigate the system outage probability of a simultaneous wireless
information, and power transfer (SWIPT) based two-way amplify-and-forward (AF) relay …

Recently, energy harvesting (EH) via radio-frequency (RF) signals in wireless relay networks
has been attracting a lot of interest, especially for supplying the energy to relay nodes in IoT …
