Abstract
Traditional communication route selection methods find the shortest communication path based on graph theory, ignoring the influence of communication parameter changes on routing selection, resulting in excessive consumption of communication resources. In order to solve the above problems, a multi-channel D2D communication routing method based on Forwarding cellular network is proposed. Based on the establishment of D2D cooperative forwarding mechanism in cellular network, the mathematical model of multi-channel D2D routing is constructed by adding QoS index. In D2D, the multi-channel routing of D2D is calculated by mathematical model. The results show that the proposed routing method not only has low transmission delay, but also can control the resource loss within 15% with good reliability.
