LTE-D2D网络的多跳路由算法研究

he wireless spectrum resources of mobile communication become more and more serious, which brings a serious challenge to the development of mobile communication. The introduction of D2D communication technology is propitious to cellular network and D2D network to share the same spectrum resources. In the cellular network, due to distance, interference and other issues, the cell edge users have poor communication quality and the experience of users is not ideal. In this paper, we propose an algorithm to improve the communication quality of the edge users and to improve the spectrum efficiency. The algorithm can effectively utilize the spectrum holes and help the edge users to choose the multi hop communication path to improve the communication quality under the premise of the controlled-interference. The theoretical analysis was verified through MATLAB simulation platform. The simulation results can be seen, the proposed D2D multi hop routing algorithm can effectively improve the communication quality of the cell edge users, and improve the cell capacity, and compared with the contrast algorithm, the algorithm has obvious advantages in the link hop number.
