METHODS FOR BUILDING A MULTI-PROTOCOL INTERNET OF THINGS INFRASTRUCTURE

Abstract

The article discusses approaches to integrating heterogeneous sensor
networks into multi-protocol information systems (MPIS). Methods of integration at three levels are
analyzed: sensors, gateways, and application level. It proposes a classification of architectural patterns,
QoS mapping rules, and mechanisms for maintaining end-to-end security during transmission between TLS
and DTLS, as well as recommendations for placing functions in Edge, Fog, and Cloud to optimize latency
and energy efficiency. The analysis concludes that combined solutions provide expanded functionality and
increased network resilience when using modular gateways, adapters, and a registry of schemes. The article
formulates practical recommendations for designing MPIs, defines criteria for selecting technology
combinations, and outlines directions for further research in validating QoS mappings and energy policies
when integrating IoT networks into a unified multi-protocol infrastructure.
Keywords: Internet of Things, multi-protocol networks, sensor networks, Edge/Fog architecture,
