基于DAG认证的网络切片场景切换算法

Network Slicing Scene Switching Algorithm Based on DAG Authentication

针对网络切片场景切换时重复身份认证导致的切换延迟问题,提出了一种基于有向无环图(DAG)认证的网络切片场景切换算法。该算法首先从DAG认证方面实现了用户场景切换的持续身份认证,确保了用户能够快速实现网络切片场景切换;然后针对多用户场景切换问题,使用了Wassertein优化下的条件生成对抗网络算法进行了场景切换优先级判定,保证了用户场景切换的低掉落率。仿真结果表明,本文算法通过避免额外的身份认证实现了更低的切换延迟,同时改善了低延迟下的掉落率性能。

To solve the problem of switching delay caused by repeated identity authentication during network slicing scene switching,a network slicing scene switching algorithm based on directed acyclic graph(DAG)authentication is proposed.Firstly,the algorithm implements the continuous identity authentication of user scene switching from the aspect of DAG authentication to ensure that the user can quickly realize the network slicing scene switching.Then,to solve the problem of multi-user scene switching,the conditional generation adversarial network algorithm under Wassertein optimization is used to determine the priority of scene switching,which ensures the low drop rate of user scene switching.Simulation results show that the proposed algorithm achieves lower handover delay by avoiding additional authentication,and improves drop rate performance under low delay..
