摘　　要：由于设备到设备(Device-To-Device,D2D)通信复用异构蜂窝网络环境的复杂性和动态性,难以实现高效、均衡的路由资源利用,文章提出D2D通信复用异构蜂窝网络中分布式路由资源分配方法。采用分布式系统模型构建D2D通信复用异构蜂窝网络的拓扑结构,基于邻居节点信息交换实现D2D设备发现,并引入自适应的会话建立策略建立通信链路,采用贪婪算法为D2D用户分配子信道,实现路由资源的均衡分配。实验结果表明,设计方法在提升D2D用户之间数据传输速率方面具有较好的性能,适用于D2D通信复用异构蜂窝网络中的路由资源分配。Due to the complexity and dynamism of Device-To-Device(D2D)communication multiplexing in heterogeneous cellular network environments,it is difficult to achieve efficient and fair utilization of routing resources.Therefore,a distributed routing resource allocation method is proposed for D2D communication multiplexing in heterogeneous cellular networks.Building D2D with distributed system model topological structure of heterogeneous cellular network with communication multiplexing,realize D2D device discovery based on neighbor node information exchange,and introduce an adaptive session establishment strategy to establish communication links.We use greedy algorithms to allocate sub channels for D2D users and achieve balanced allocation of routing resources.The experimental results show that the design method has good performance in improving D2D users and rates,and is suitable for routing resource allocation in D2D communication multiplexing heterogeneous cellular networks.
