摘　　要：利用终端直连(D2D)技术进行分组转发的策略虽然能够提升蜂窝整体性能,但也同时存在安全性和有效性较差的问题,而社交属性的加入将有助于这些问题的改善。因此,提出一种利用社交属性的D2D分组转发策略,加入社交属性的同时利用中餐馆(CRP)算法进行分组。仿真表明,该策略可以在考虑安全性的同时提升频谱效率,减轻基站负载。Although the strategy uses device-to-device technics to cluster and fro＇ward can improve the performance of cell, it still lacks of safety and efficiency. But those problems can be made up by adding social attributes. Therefore, this paper will raise a novel strategy which takes the social attributes into consideration. At the same time, it utilizes the Chinese Restaurant Process（CRP） algorithm to cluster. The simulation result shows this strategy can improve the spectral efficiency and reduce the load of base station while considering safety.
