About this Research Topic
Massive connectivity of low-powered and smart battery-less devices is a key technology to enable Internet of Everything (IoE) for the 6th generation (6G) mobile network. How to prolong the life expectancy of the battery-less devices is a key challenge. Two complementary aspects have drawn increasing attention for the above challenge: 1. energy efficiency for low-power devices, and 2. energy harvesting and wireless information and power transmission (WIPT). Emerging wireless technologies such as THz, intelligent reflective surface (IRS), ambient energy harvesting, and backscatter communications provide great potential to fulfil this energy self-sustainability vision for 6G. For instance, THz is more efficient than lower frequencies for WIPT as higher frequencies can provide better directionality. IRS may actively or passively transmit or relay information signal to IoE devices, and also more energy efficiency in radio propagation environments with a lot of obstacles, such as in downtown areas. Some prototypes of battery-less devices have been shown to be able to harvest energy from ambient wireless signals from base stations, TV towers, and wifi.
This special issue solicits articles emphasizing on the theory or practice of energy efficiency and harvesting of IoE devices, by exploiting emerging new 6G technologies. Prospective authors are invited to submit original research manuscript or review/vision papers on topics including, but not limited to
• Network architecture to support power efficiency and energy harvesting for IoE/IoT devices in 6G
• Energy efficient THz based transceiver for WIPT
• Intelligent reflective surface based communication and energy charging
• Reconfigurable transceiver design for active or passive information and power transfer
• Theory or experiment for ambient energy harvesting
• Theory or experiment for backscatter communications
• Visible light based transceiver design for joint information and power transfer
• Massive access for battery-less smart devices
• UAV assisted IoE/IoT access algorithms and protocols
• Localization and tracking for battery-less devices
