Analysis of Technologies for Reconfiguration of IoT Systems at Level of Software Modules and Bootloaders

The analysis of existing components of a smart home as part of the entire range of Internet of Things (IoT) is performed. The analysis of possible ways of reconfiguration of IoT components is performed. The ways of reconfiguration at the network level and partial node reconfiguration are considered. The ways of flexibility of the components of IoT are analyzed and classified. Comparative analysis of summarized parameters of bootloaders is performed. The possibility to use the software components as unchangeable blocks of the code for modification of microcontroller program as the way of reconfiguration is analyzed. The idea to use the replaceable software modules for representation of microcontroller program at higher level of abstraction with modified bootloader is proposed. Elements of programming method for microcontroller reprogramming with replaceable software modules as middleware is proposed. The practical example of the use of results of the research is provided.
