Special Issue Information

Dear colleagues,

Wireless power transfer (WPT) technologies have been considered as promising solutions for supplying power to mobile devices. In particular, radio frequency (RF) based WPT technologies have recently attracted a great amount of research interest, since the WPT can remove the last wire of mobile devices and provide real mobility for Internet of Things (IoT) environments. Since RF signals are simultaneously exploited for wireless communications, i.e., wireless information transfer (WIT), a joint optimization of WPT and WIT should be carefully designed.

This Special Issue will focus on emerging joint technologies of WPT and communications. Potential topics include but are not limited to the following:

  • Simultaneous wireless power and information transfer (SWIPT);
  • Wireless powered communication networks (WPCN);
  • WPT hardware testbed and implementation;
  • Safety issues for WPT;
  • Low power communication protocol for WPT;
  • Far-field RF energy transfer circuits and antennas;
  • Near-field energy transfer technologies.

In this paper, we examine non-orthogonal multiple access (NOMA) and relay selection strategy to benefit extra advantage from traditional cognitive radio (CR) relaying systems. The most important requirement to prolong lifetime of such network is employing energy harvesting in the relay to address network with limited power constraint. In particular, we study such energy harvesting CR-NOMA using amplify-and-forward (AF) scheme to improve performance far NOMA users. To further address such problem, two schemes are investigated in term of number of selected relays. To further examine system performance, the outage performance needs to be studied for such wireless powered CR-NOMA network over Rayleigh channels. The accurate expressions for the outage probability are derived to perform outage comparison of primary network and secondary network. The analytical results show clearly that position of these nodes, transmit signal to noise ratio (SNR) and power allocation coefficients result in varying outage performance. As main observation, performance gap between primary and secondary destination is decided by both power allocation factors and selection mode of single relay or multiple relays. Numerical studies were conducted to verify our derivations. Full article
