Home Device Mesh Communication Using REST-Based Function Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home device communication systems require a central point for network supervision, necessitating device registration and limiting direct device-to-device communication, and rely on strict address-based data transmission, which is inflexible and requires multiple communication modules.
Innovation Solution
A mesh topology network where each device is equally privileged, allowing direct communication without a central unit, using REST-formatted signals with semantic function names, eliminating the need for individual addressing and central directories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized home network is used with a central node supervising all transmissions, then device control and monitoring are simplified, but device complexity and network capacity are limited
Solution Approach 1:
The patent divides the centralized network into multiple decentralized mesh network segments, where each device acts as an independent node capable of routing messages. This segmentation eliminates the single point of control while maintaining manageable complexity through standardized communication protocols.
Solution Approach 2:
Each device in the mesh network is designed to perform multiple functions: acting as an endpoint for control, a router for message transmission, and a relay for other devices. This multi-functionality reduces the need for specialized central nodes while simplifying overall network operation.
2Reliability
If device registration and installation in a central node is required before first use, then device authorization is controlled, but ease of operation and device integration are reduced
Solution Approach 1:
Devices automatically register themselves with other nodes in the mesh network through broadcast messages containing their device identifiers and capabilities. This self-service registration eliminates manual configuration while maintaining authorization through cryptographic verification of device identities.
Solution Approach 2:
Device authorization information is pre-configured in the devices during manufacturing. When a device joins the network, it automatically presents this pre-configured authorization data, eliminating the need for runtime registration while ensuring secure access control.
3Reliability
If all data must be sent through a central node, then network supervision is centralized, but communication speed and network capacity are limited
Solution Approach 1:
The patent merges the functions of central supervision and data transmission by enabling each node to simultaneously perform monitoring and routing. This combination allows parallel data paths through multiple nodes, increasing transmission speed while maintaining distributed supervision capability.
Solution Approach 2:
The mesh network dynamically selects optimal transmission paths based on current network conditions, node availability, and message priority. This dynamic routing adapts to changing conditions in real-time, maximizing transmission speed while maintaining reliable supervision through multiple redundant paths.
4Measurement precision
If traditional addressing methods are used with device addresses, then device identification is precise, but adaptability and functionality are limited
Solution Approach 1:
The patent changes the addressing parameter from static device addresses to dynamic service-based identifiers. Devices are identified by the services they provide (e.g., lighting control, temperature regulation) rather than fixed addresses, allowing flexible assignment and reassignment of functions while maintaining precise identification through service type and instance parameters.
