Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current short-range wireless communication technologies like Bluetooth and Wi-Fi face high maintenance costs due to frequent topology changes in mobile scenarios with multiple devices, leading to resource overheads.
Innovation Solution
A networking device communication method where a primary device sets a timing correspondence for secondary devices to receive and send broadcast messages at specific timings within a communication window, reducing topology changes and resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional star, tree, or mesh topologies are used in mobile scenarios with multiple devices, then device communication is enabled, but frequent topology changes occur leading to high maintenance costs and resource overheads
Solution Approach 1:
The patent implements periodic communication windows with fixed timing structures where devices transmit data at predetermined intervals rather than continuously. The primary device sends broadcast messages at specific time slots, and secondary devices respond at designated response windows, creating a periodic communication pattern that stabilizes the network topology and reduces maintenance overhead in mobile scenarios
2Reliability
If devices continuously adjust communication timing to maintain optimal connectivity in mobile scenarios, then communication quality is improved, but resource overheads and energy consumption increase
Solution Approach 1:
The patent establishes continuous periodic communication windows that maintain stable connectivity without requiring devices to frequently adjust their communication patterns. Once the timing structure is established, devices continuously operate within this framework, eliminating the need for constant re-synchronization and reducing energy consumption associated with dynamic topology adjustments
3Loss of information
If broadcast messages are sent at every communication window timing, then all devices receive updates promptly, but resource overheads increase due to unnecessary transmissions
Solution Approach 1:
The patent implements selective broadcasting where the primary device determines whether to send broadcast messages based on the specific timing and content requirements. Instead of sending broadcasts at every communication window, messages are transmitted only when necessary at appropriate time slots, reducing redundant transmissions and resource overhead while ensuring all devices receive necessary updates

AI summary
This application provides a networking device communication method and an electronic device, which may be used in a networking communication scenario. The method includes: A primary device in a network determines a correspondence between a device identity ID of a secondary device and a timing, and indicates the secondary device to: send a broadcast message in a communication window of the primary device based on a corresponding timing, and receive a broadcast message in the communication window of the primary device at a non-corresponding timing.
