摘要

对于物联网终端而言，如何有效降低共信道干扰，提高传输接入速率是当前需要解决的关键问题。本文利用D2D通信技术提高物联网网络的数据速率和频谱效率，在此基础上提出了一种基于最大容量增益的D2D资源分配方法。该方法首先利用几何规划算法的功率控制来调节通信干扰。然后，利用匈牙利算法实现频谱资源与D2D终端的最佳匹配。仿真结果表明，所提出的资源分配方法可以提高传输接入率和系统容量增益。

A D2D resource allocation method for IoT network

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.
