Abstract. Current demographic changes have made it necessary to implement innovative solutions in order to respond to elderly people's needs. This paper describes a concept designed to cater for such users' needs via modern technologies. Survey data and end-users feedback were collected and processed in order to identify the most frequent types of use cases, such as in-home health monitoring, house monitoring, fall down detector, automatic door lock, indoor mobility patterns. The architecture we suggest is service oriented, it uses a general representation of data, and protocols for communication and is flexible enough to provide more services than the already existing one. The platform's design for the core subsystem boosts the effectiveness of sensor measurements by applying near real-time processing algorithms via Complex Event Processing engine, or by offering integrated messaging mechanisms. We use the Business Process Management Workflows to define new treatments for the elderly, and to generate medication and medical check alerts. The concept described here opens the way for app developers to extend the platform's functionalities. Developing and deploying the corresponding plug-ins ensure the platform's adaptability requirement.
The design and implementation of secure IoT platforms and software solutions represent both a required functional feature and a performance acceptance factor nowadays. This paper describes relevant cybersecurity problems considered during the proposed microservices architecture development. Service composition mechanisms and their security are affected by the underlying hardware components and networks. The overall speedup of the platforms, which are implemented using the new 5G networks, and the capabilities of new performant IoT devices may be wasted by an inadequate combination of authentication services and security mechanisms, by the architectural misplacing of the encryption services, or by the inappropriate subsystems scaling. Considering the emerging microservices platforms, the Spring Boot alternative is used to implement data generation services, IoT sensor reading services, IoT actuators control services, and authentication services, and ultimately assemble them into a secure microservices architecture. Furthermore, considering the designed architecture, relevant security aspects related to the medical and energy domains are analyzed and discussed. Based on the proposed architectural concept, it is shown that well-designed and orchestrated architectures that consider the proper security aspects and their functional influence can lead to stable and secure implementations of the end user’s software platforms.
In this paper we define a new integral operator and we obtain univalence criteria for this integral operator.
