Special Issue Information

Dear Colleagues,

Advanced radio frequency (RF) energy harvesting (EH) and wireless power transfer (WPT) technologies are paving the way towards future wireless networks. WPT via RF radiation has emerged as a promising approach to energise low-power devices in circuit design. While traditional wireless networks were designed only for data communications, the future of wireless communications allows both data and energy transmission, i.e., simultaneous wireless information and power transfer (SWIPT), using the same radio wave over the same wireless medium. Although EH and WPT have shown to be able to sustain the energy supply, enabling the development of numerous applications and services in various wireless network architectures, there are challenges in theoretical modeling, analyses and practical design that need to be addressed. This Special Issue aims to provide a comprehensive overview of state-of-the-art technologies and theories of EH and WPT in practical wireless networks.

Prospective authors are invited to submit original manuscripts on topics including, but not limited to:

  • RF EH for low-power wireless transceiver circuits in communication systems;
  • EH interface circuit design for light-weight devices;
  • Antenna, waveform and signal design for EH and WPT;
  • Network architecture and protocol design for RF EH and WPT;
  • Analytical models of EH and WPT in network architecture design;
  • RF EH and WPT in unicast, multicast, broadcast and relay channels;
  • RF EH and WPT with cooperative communications, multiple-input multiple-output (MIMO), massive MIMO and mmWave technologies;
  • SWIPT in wireless sensor networks, device-to-device communications, Internet-of-Things (IoT) and cellular networks (5G and beyond);
  • Security in SWIPT systems;
  • Experiment and prototype of RF EH, WPT and/or SWIPT.

Outage Performance of Power Beacon-Aided Multi-Hop Cooperative Cognitive Radio Protocol Under Constraint of Interference and Hardware Noises

In this paper, we evaluate end-to-end outage probability of a multi-hop decode-and-forward relaying protocol in underlay cognitive radio network. In the proposed protocol, named COOP, secondary nodes including source and relays have to harvest radio-frequency energy from multiple secondary power beacons, and adjust their transmit power, follows a pre-determined interference threshold given by multiple primary users. To enhance the outage performance for the secondary network under an joint constraint of the interference threshold, Rayleigh fading channel and hardware noises caused by imperfect transceiver hardware, the secondary relays on the source-destination path cooperate to forward the source data to the destination. Particularly, they attempt to receive the source data from their previous nodes, and forward it to the secondary destination if requested. Moreover, whenever the destination cannot receive the source data successfully, a successful relay that has the shortest distance to the destination is selected for retransmission. Due to usage of the cooperative transmission, the proposed COOP protocol obtains better performance, as compared with the corresponding multi-hop relaying one (denoted DIRECT) which only uses direct transmission at each hop. We evaluate the outage performance of COOP and DIRECT via both simulation and theory. The obtained results present a significant performance enhancement, as comparing COOP with DIRECT. Full article

Over the decades, with the advancement of science and technology, wheelchairs have undergone remarkable changes, such as controlling an electrical wheelchair by using brain signals. However, existing electrical wheelchairs still need improvements in terms of energy management. This paper proposes an hybrid Solar-Radio frequency (RF) harvesting system able to supply power for the continuous and effective operation of electrically powered wheelchairs. This system can simultaneously harvest power from RF and solar source that are both available in the surrounding environment. A maximum power point tracking (MPPT) and a boost converter are exclusively employed for the standalone solar system while the standalone RF system is equipped with a 9-stage voltage multiplier (VM). The voltage level for the charging process is obtained by adding the output voltage of each source. In addition, a current booster and a stabilizer are used to reach the required level of current and pin the charging voltage to a stable level, respectively. Simulation results show how the hybrid system is better and more stable when the boost current and stabilizer are used in the charging system. Moreover, we also provide some analytic results to prove the advantages of this system. Full article

In this paper, we consider the resource allocation problem to maximize the minimum (max–min) user’s secure energy efficiency (SEE) in downlink massive multiple-input multiple-output (MIMO) systems with simultaneous wireless information and power transfer (SWIPT). First, transmission power and power splitting ratio are designed to achieve the max–min user’s SEE subject to harvested energy threshold, the constraints of transmission power, and power splitting ratio. Secondly, the optimization problem is non-convex and very difficult to tackle. In order to solve the optimization problem, we converted to a series of parameter optimization subproblems by fractional programming. Then, we employ the first-order Taylor expansion and successive convex approximation (SCA) method to solve parameter optimization problems. Next, a secure energy-efficient resource allocation (SERA) algorithm with the bisection method is proposed to find the max–min SEE of the system. Finally, simulation results show the effectiveness and superiority of the SERA algorithm. Full article
