A Scalable Approach to IoT Interoperability: The Share Pattern

Area of Science:

• Computer Science
• Distributed Systems
• Internet of Things

Background:

• The Internet of Things (IoT) connects billions of devices, but integrating heterogeneous systems, especially in healthcare, is challenging due to proprietary standards.
• Isolated ecosystems and proprietary standards hinder interoperability in the rapidly growing IoT landscape.

Purpose of the Study:

• To present an extended version of the Share design pattern for dynamic service composition on resource-constrained IoT devices.
• To enable decentralized, peer-to-peer integration of IoT services using a lightweight, contract-based mechanism.

Main Methods:

• Developed an extended Share design pattern for lightweight, contract-based dynamic service composition.
• Utilized LUA programming language for executable code exchange and decentralized, peer-to-peer service integration.
• Created a LUA-based emulator to verify structural and behavioral constraints of service interactions.

Main Results:

• The Share design pattern demonstrated scalability and effectiveness in resource-constrained IoT environments.
• The pattern supports formal correctness through design-by-contract principles, ensuring reliable service interactions.
• Decentralized, peer-to-peer integration was achieved through dynamic service discovery and contract validation.

Conclusions:

• Share is a promising solution for creating lightweight, interoperable IoT systems.
• The pattern offers flexibility, dynamic configuration, and resilience without reliance on centralized infrastructure.
• Contract-based integration ensures formal correctness and enhances the reliability of IoT service interactions.
