D2D通信系统中中继辅助的资源分配算法研究
在D2D（Device—to—Device）通信中引入中继节点可以延伸蜂窝覆盖范围，提高系统性能。在中继辅助的D2D通信中，中继节点的选择是关键。提出了一种中继辅助的资源分配算法，讨论了中继节点的选择问题，同时根据社交关系因素和距离因素来选择最优中继。该方案保证了通信链路的QoS（Quality of Service），并且使得系统吞吐量达到最大。仿真结果表明，距离和社交关系因素都对D2D通信产生很大影响，同时考虑两个因素比单纯考虑社交关系因素或者距离因素性能提高很多。...

| Bibliography: | Introducing the relay nodes in D2D（Device-to-Device） communication can extend the range of cellular coverage and improve the system performance. The selection of relay nodes is the key point in relay-assisted D2D communication. In this paper, a relay-assisted resource allocation algorithm is proposed. The selection of relay nodes is discussed, and the optimal relay nodes is considered both social relation factors and distance factors. This scheme guarantees the QoS （Quality of Service）of the communication link and maximizes the system throughput. The simulation results show that both distance and social factors have great influence on D2D communication, and considering the two factors are much better than only considering the social factors or distance factors.
