Economic expediency encourages mobile operators to deploy 5G networks in places with a high concentration of speed-demanding subscribers. In such conditions, sharp fluctuations in the volume of traffic with regulated requirements for the quality of service are inevitable. Note that 5G operates in the millimeter range.

Article Synopsis
- Biomedicine approaches to epidemic analysis are relevant for understanding cyber epidemics, focusing on aspects like growth patterns, pathogen adaptations, and preventive measures.
- The article emphasizes early-stage prediction of cyber epidemics, addressing challenges like limited and distorted data that complicate AI model application.
- To tackle this, the authors introduce an entropy-extreme model, leveraging probability distributions of controllable parameters, which effectively conducts predictions and outperforms traditional methods in forecasting malware infection trajectories on Windows devices.
Article Synopsis
- - The Internet of Medical Things (IoMT) has enhanced healthcare by linking medical devices and patients, but it raises privacy concerns due to the vulnerability of sensitive data to security threats.
- - The paper introduces a Timestamp-based Secret Key Generation (T-SKG) scheme that creates secret keys directly on patient devices and regenerates them on doctors' devices, reducing the risk of key compromise.
- - Simulation results show that T-SKG provides strong security against various attacks, with only a 9% chance of key compromise in guessing attacks, while also utilizing the Data Encryption Standard (DES) for data encryption in transmitting health vitals.
Rerouting of direct information traffic under the WiMax-1/2 technology control in the case of licensed frequency spectrum overload ensures communication continuity in the smart city's critical infrastructure. The support of such a process in the WiMax-1/2 cluster has its specificity, worthy of analytical formalization. The article presents a mathematical apparatus that allows the average service duration of an information message during its transfer from the terminal to the WiMax-1/2 base station to be estimated.

A fundamental feature of the author's formulation of the extreme problem is that it takes into account not only the points of potential placement of base stations but also the possibility of selecting instances of stations to be placed at a specific point from a defined excess set, as well as the aspect of inseparable interaction of placed 5G base stations within the framework of SON. The formulation of this extreme problem is brought to the form of a specific combinatorial model.
