Wireless Communication Device Master Unit Priority Negotiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, such as those using IEEE 802.11 and Wi-Fi Direct, may form communication groups with inefficient data paths when multiple devices are connected, leading to suboptimal data transmission routes.
Innovation Solution
A wireless communication device that receives application information about nearby devices, sets parameters based on the number of content providers and users, and controls negotiations to determine the master-slave relationships, optimizing the data path by adjusting priorities dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If each wireless communication device sets its own master unit priority parameter independently, then device autonomy and ease of operation are improved, but the data path efficiency and topology optimization deteriorate when three or more devices are connected
Solution Approach 1:
The patent changes the priority parameter setting from static device-independent values to dynamic device-specific values based on application roles. Content providing devices are assigned higher priority parameters to become master units, while content user devices receive lower priority parameters. This parameter adjustment resolves the contradiction by optimizing data path efficiency through role-based priority assignment while maintaining device autonomy in parameter negotiation
Solution Approach 2:
The patent implements a feedback mechanism where devices exchange application information about their content providing or user status during the connection negotiation process. This feedback allows each device to adjust its master unit priority parameter based on the other device's role, ensuring that content providing devices become master units and establish efficient data paths without centralized control
2Adaptability or versatility
If a communication group is formed with arbitrary device connections, then device versatility and adaptability are improved, but data transmission delays and resource utilization efficiency deteriorate
Solution Approach 1:
The patent introduces application-role-based priority parameters that dynamically adjust master unit selection based on content providing or user status. This ensures that devices with content to share automatically become master units, creating optimized data paths that reduce transmission delays while maintaining the flexibility of ad-hoc device connections without requiring pre-configured topologies
