A D2D resource allocation method for IoT network

Abstract

For IoT terminals, how to effectively reduce cochannel interference and increase the transmission access rate are key issues that need to be resolved at present. In this paper, D2D communication technology is employed to improve the data rate and spectrum efficiency of IoT network, based on which a D2D resource allocation method with respect to maximum capacity gain is proposed. This method adjusts communication interference by using power control with a geometric programming algorithm first. Then, Hungarian algorithm is utilized to achieve the best match between spectrum resources and D2D terminals. Simulation results show that the proposed resource allocation method can improve the transmission access rate and system capacity gain.
