Wireless powered communication networks in interference channel

2017 IEEE International Conference on Communications (ICC), 2017
In this paper, we study a wireless powered communication network (WPCN) in a two-user interference channel, where two hybrid access-points (H-APs) support a user in each cell. In this two cell scenario, the H-APs first transmit the energy signal to charge both users in the downlink (DL) phase.

Opportunistic Scheduling in Wireless Powered Communication Networks

IEEE Transactions on Wireless Communications, 2017
In this paper, we apply the notion of opportunistic scheduling in wireless-powered communication networks (WPCNs). The considered WPCN model consists of a base station (BS) and multiple energy harvesting users (EHUs), where the BS broadcasts radio frequency energy to the EHUs over the downlink and receives information from the EHUs over the uplink.

Mobile power management for wireless communication networks

Wireless Networks, 1997
For fixed quality-of-service constraints and varying channel interference, how should a mobile node in a wireless network adjust its transmitter power so that energy consumption is minimized? Several transmission schemes are considered, and optimal solutions are obtained for channels with stationary, extraneous interference.

Energy-Neutral Wireless Sensor Network Based on SWIPT in Wireless Powered Communication Networks

ICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020
For energy-neutral operation (ENO) of wireless sensor networks (WSNs), we consider a WSN deployed in a wireless powered communication network. In this network, sensor nodes with high harvesting energies and good link budgets have energy remaining after sending their data to the cluster head (CH), whereas the CH suffers from energy scarcity.

Analysis and Power Scheduling Algorithm in Wireless Powered Communication Networks

2020 16th International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob), 2020
Wireless powered communication networks (WPCN) which allow an energy source (ES) to wirelessly transfer its power to a wireless device (WD) is becoming a promising technology in modern wireless networks. Besides extending network longevity, WPCN eliminates the need for frequent manual battery replacement or recharging. Even WPCN is a potential solution,

Cognitive Wireless Powered Communication Networks with Hybrid Backscatter Communication

2018
In this chapter, a hybrid mode scheme is proposed for a CWPCN. The CWPCN consists of a primary communication system and a secondary communication system, where the cognitive user (CU) can adopt the HTT mode, the AB mode or the BB mode following the proposed hybrid mode scheme. The primary transmitter (PT) and the PB serve as the incident signal sources
