IoTaaS based Approach to Design of a WSN for Secure Smart City Monitoring

The paper proposes a new approach to designing a software for Digital City systems. These systems are built on the basis of wireless sensor networks and implement Internet of Things as a Service (IoTaaS) concept. The approach is based on a proposed knowledge model of distributed systems for design and testing of devices in the Digital City. This approach comprises a specific service-oriented architecture and software prototypes of design and testing tools. The suggested approach increases the automation level of the development process of such systems. It will contribute to reducing time of the development process and operating costs of the developers. The peculiarities of the approach include the use of rules for the interconnection of particular hardware units, on the one hand, and ways of software devices modeling, on the other. Besides, the originality is in application of specific Digital City services by using virtualization tools.
