This article studies the relay selection strategy of Device to Device (D2D) technology in 5G communication. By comprehensively considering the transmission channel quality and the cache queue length of relay nodes, the optimal strategy for D2D relay selection is determined. Simulation shows that the proposed strategy can effectively provide system throughput. The research results of this article provide a feasible reference direction for the upgrade of local communication technology in electricity information collection systems.
