Prototyping and Rapid Development of IoT Systems in Context of Edge Computing

Currently, Cloud, IoT, Dew, Edge and touch networks of “things” are allocated as part of the program system. Data at the touch network level is associated with physical objects. At the Edge level, data is separated from objects to form a Digital Twin representation of their state, properties, and behavior with minimal latency. Copies of Digital Twin “things” are stored and used at different levels, but must reflect their current state. Interaction with “things” in IoT, data transport between sensor networks through their boundary nodes is considered. For Edge computing research it is proposed to create physical and virtual models of fragments of touch networks, their boundary nodes, processing of data and organization of access of devices as part of “things” to remote IoT resources. The paper shows how to build a virtual device model in a Proteus environment and assess adequacy versus a physical model. Implemented a piece of wired sensor network with TCP/IP protocol based on open platforms.
