摘要 D2D协作通信技术可以满足提高蜂窝通信系统容量、扩大网络覆盖范围的通信需求。针对一些边缘用户受到信道衰落影响较大,从而影响用户的服务质量问题,提出了一种将拍卖原则引入D2D协作通信的中继选择算法。该算法首先在满足D2D通信要求和信噪比限制条件下得到中继备选集合;然后以优化链路吞吐量为目标选择最优中继节点;最后当两个或多个用户同时选中一个最优中继节点时,采用拍卖原则为D2D发射端分配最终中继。仿真结果表明,所提算法不仅有效地提高了吞吐量,同时保证了系统的中断概率。

英文摘要 The D2D cooperative communication technology can satisfy the communication wants of increasing the capacity of the cellular communication system and expanding the network coverage. Aiming at the problem that channel fading are greatly affecting some edge users and affecting the quality of service of users, this paper proposed a relay selection algorithm that leaded the auction principle into D2D cooperative communication. The algorithm first obtained the relay candidate set under the condition of satisfying the D2D communication requirement and the signal-to-noise ratio limitation. Then it selected the optimal relay node with the target of optimizing the link throughput. Finally, when two or more users selected the same superior relay, it allocated the final relay for D2D transmitting with auction principle. The simulation results show that the proposed algorithm not only effectively improves the throughput, but also ensures the interrupt probability of the system.
