摘　　要：目前,D2D通信的中继选择方法主要考虑如何提高系统容量和降低中断概率,但很少考虑中继设备对转发数据带来的安全问题。因此,笔者提出基于数据安全的D2D通信中继选择算法。首先分析D2D中继用户的剩余能量、联系深度和社交关系对中继转发数据的安全性能的影响,并以此为依据从候选中继用户中选择能够保证转发数据安全性更高的中继用户;其次利用改进的模拟退火算法优化中继选择和系统容量;最后通过仿真验证了所提算法不仅能保证中继转发数据的安全性,还可以提高D2D通信系统的总容量。At present,the relay selection method of D2D communication mainly considers how to improve the system capacity and reduce the probability of interruption,but rarely consider the security problem brought by relay equipment to forwarding data.Therefore,the author proposes a D2D communication relay selection algorithm based on data security.Firstly,the residual energy of D2D relay users,the influence of contact depth and social relationship on the security performance of relay forwarding data are analyzed,and based on this,the relay users that can ensure higher security of forwarding data are selected from the candidate relay users.Secondly,the improved simulated annealing algorithm is used to optimize the relay selection and system capacity.Finally,it is verified by simulation that the proposed algorithm can not only ensure the security of relay forwarding data,but also improve the total capacity of the D2D communication system.
