**6. Conclusion**

We have presented an idea of a smart city organized in edge and fog nodes to manage vital signs-based healthcare services. In the future, each citizen will wear a smart band or smartwatch, which will help monitor vital signs, and input data into the architecture. With data from the whole city, public sectors can proactively address healthcare problems in particular districts or develop public strategies destinated to a particular aging interval. We are confident that the future will combine edge, fog, and cloud resources with supporting critical and non-critical services. The term critical here can be understood that services must be executed with high priority, for example, when involving older people with diseases or chronic problems or when addressing health services where the latency time is crucial, like ECG.
