Relay selection algorithm based on selfish behavior analysis in ultra-dense D2D

open access: yesTongxin xuebao, 2021
In ultra-dense D2D communication, the current relay selection schemes mainly assume that the relay device has the initiative to participate in data forwarding, but some rational relay devices may delay or refuse to forward due to their own considerations,
