Multi-Device Routing via Intermediary Nodes for Wearable Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies like Bluetooth and ZigBee only support 1:1 connections, preventing network routing among multiple devices, which limits their ability to connect devices not physically linked in an IP network.
Innovation Solution
A method and host device that search for communicatable devices, generate routing paths, and select paths based on preset references such as service execution, security levels, location, or access authorities to enable communication among multiple devices, including wearable devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Bluetooth or ZigBee communication technology is used, then devices can be connected without a medium, but only 1:1 communication is supported and routing is not possible
Solution Approach 1:
The patent introduces intermediary devices (first device and second device) that act as mediators to enable communication between the host device and wearable device. These intermediaries facilitate multi-device connectivity by establishing communication paths through devices that are not directly connected, thus resolving the limitation of 1:1 communication while maintaining the simplicity of the underlying communication technology.
2Adaptability or versatility
If routing is implemented to connect devices not physically linked, then communication among multiple devices becomes possible, but the communication technology must support many-to-many connection
Solution Approach 1:
The patent segments the communication path into distinct segments: host device → first device → second device → wearable device. Each segment represents a separate communication link that can be established independently using standard 1:1 communication protocols. This segmentation enables multi-device connectivity without requiring complex many-to-many routing protocols.
3Reliability
If multiple routing paths are generated for communication, then communication reliability improves, but the process of searching and selecting paths increases complexity
Solution Approach 1:
The patent implements a feedback mechanism where the host device receives communication status information from the wearable device and uses this feedback to determine whether communication was successful. Based on this feedback, the system can identify which routing path was used and adjust future path selection accordingly, improving reliability while keeping the selection process simple through direct feedback rather than complex analysis.

AI summary
A host device and a method of communicating with a plurality of devices are provided. The method includes operations of searching for devices that are communicatable with the host device, generating routing paths connected to a wearable device via devices found by the host device, selecting one of the routing paths according to a preset reference, and communicating with the wearable device via at least one of the found devices included in the selected routing path, wherein the preset reference includes a first reference that is set according to a service executed by the host service, or includes a second reference that is set according to a security level of each of the found devices.
