Research on Energy Efficiency Optimization of Device-to-Device Network Based on Blockchain
Min Wang, Qiaoyun Sun, Zhang Shu-guang, Yu Zhang · 2021
In the device-to-device (D2D) network, a large number of applications directly perform computing and storage tasks on intelligent terminal devices, but it brings huge energy consumption pressure to the energy limited intelligent terminal. In order to improve the green energy-saving user experience of intelligent terminal, the blockchain technology is used to actively mobilize the redundant resources in D2D network, and a reasonable and flexible D2D network resource sharing management strategy is proposed to improve the network energy efficiency. In order to solve the problem of lack of trust foundation and incentive mechanism in collaborative computing between intelligent terminals in D2D network, it uses blockchain technology to provide a safe and reliable cooperation platform, adopts appropriate incentive mechanism to encourage intelligent terminals to participate in cooperation, realizes optimal pairing, and uses reputation value proving machine as consensus mechanism, which can avoid resource waste and energy consumption caused by mining tasks in traditional blockchain.
