Abstract
As one of the main technologies of 5G, device-to-device (D2D) technology directly transmits data between mobile terminals in the adjacent area, and there is no need for base station relay equipment to transfer, so as to realize high data rate transmission, improve communication capacity, reduce transmission delay, and make full use of wireless spectrum resources. With the support of D2D technology, cellular wireless communication can be avoided between devices, so that wireless communication can be realized without occupying the bandwidth resources. In this paper, with the support of D2D technology, firstly, the transmission path optimization of D2D technology is realized by artificial swarm algorithm. Secondly, the simulation is carried out by MATLAB software. Finally, the path optimization of D2D communication is realized by simulation, and the test results are compared and analyzed.
