Research on Green Relay Algorithm for 5G Ultra Dense Networks
Aiming at the energy consumption control problem of mobile stations to be transferred in light load cellular networks in the process of switching relay access points,a green relay algorithm for 5G ultra dense networks with quality of service was proposed.This algorithm developed a green relay scheme based on channel differentiation by identif-ying relay stations and relay network types.The proposed scheme effectively constrained the energy consumption of all channels of device to device data communication,relay stations,and mobile stations.At the same time,a load assess-ment mechanism was introduced and the optimal rate access function was used to screen out more optimal relay schemes from the optimal relay channels,effectively avoiding the risk of overall network load imbalance after the switching of the ac-cess points of the mobile station to be transferred.The experimental results showed that the green relay algorithm could a-chieve optimal energy consumption management while ensuring the quality of data communication service from devices to devices.In 5G ultra dense networks with larger coverage and more mobile devices,the energy management advantages of algorithms were more obvious.
