Abstract: Aiming at the poor effect of D2D ( Device-to-Device) communication channel allocation, an optimization mathematical model of D2D communication channel allocation based on KM (Kuhn Munkras) algorithm is proposed. Based on the model of D2D communication system, the transmission rate of D2D communication channel is calculated, and the variables in the system are expressed in a two-dimensional coordinate system. A linear planning diagram is constructed, according to which the optimal transmission power of D2D users is solved. Based on KM ( Kuhn Munkras) algorithm, the mathematical model of D2D communication channel allocation optimization is established to realize D2D communication channel allocation. The experimental results show that the practical application effect of D2D communication channel allocation optimization mathematical model is better, and the throughput of communication system is greater.
