The principle of 5G architecture is software-based, and this is the drawback of this high standard network in terms of user security, which means the 5G wireless network is sensitive to security foible. In the case of 5G network slicing, the 5G operator will provide diverse services over the virtualized network. Maintaining the security of this virtualized network is a challenging task for vendors, operators, service providers, software developers, users, and all those who are a part of this system. We already discussed above that the 5G NSA architecture combines the use of New Radio and LTE network core. As a result, these networks take over all the security issues of LTE networks from the get-go [19]. Research already indicated vulnerable issues in LTE networks for denial of service (DoS) through diameter exploitation. This means the 5G NSA network will be vulnerable to DoS, too.

5G will also provide key network technology changes that will enable AI use cases. 5G networks will provide an environment with high reliability, ultra-high data speeds, extremely low latency, very low packet loss, and flexible use of licensed and unlicensed spectrum. The increase in throughput and connection density coupled with drastic reduction in network latency ushers in many use cases where AI can be applied to automate industrial and personal applications. In addition, with 5G network slicing, a service provider can share one common network infrastructure to address the diverse needs from very different applications simultaneously.

The simulation results from the VFH transportation application use case implemented in a 5G network slicing revealed that uncertainty introduced by humans affects network performance. Based on the results, it can be concluded that as uncertainty increases, network performance drastically decreases. A future line of research that can help expand our understanding of uncertainty for these scenarios is to analyze these results under the theory of networks. Approaches such as node centrality with its metrics of betweenness centrality and closeness centrality, and spectral node centrality with the Katz centrality metric, can offer clues or explanations to possible nodes that generate more congestion (Rueda et al., 2017), and that would require dynamic resource management.
