MEC provides computation power at the network edge that decreases the latency of requests. However, MEC faces resource allocation and mobility issues that need solving to benefit from this technology. Some solutions found in the literature were discussed, but further study is still needed. Network slicing gives a solution to differentiate the requirements of the services to follow the best protocol for dealing with each request. Blockchain technology is key to supply both security and authentication required by healthcare applications. Moreover, blockchain powered with AI smart contracts opens new opportunities in healthcare IoT applications. Integrating these technologies has a great poten- tial for realizing Healthcare 4.0, as shown by the patient monitoring case study. Scalability and identity management issues of this integration should be solved to allow the realization of this system practically. Solving these issues will also allow further study of hosting federated learning and decision-making systems on edge securely. REFERENCES 1. Rep. MHealth and Home Monitoring - 9th Edition.
