Wi-Fi Direct Group Owner Selection via Network Capability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wi-Fi Direct communication technologies face inefficiencies in determining a group owner, leading to suboptimal network connections, as the selection is based on random group owner intent values rather than network information.
Innovation Solution
A method is introduced where devices determine a group owner by comparing network information regarding internet access ability, allowing for dynamic adjustment of group owner intent values based on specific network situations, ensuring efficient network management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If group owner intent values are compared to determine group owner, then devices can establish connection, but the network connection efficiency is poor due to random selection
Solution Approach 1:
The patent changes the parameter used for group owner determination from random intent values to network capability parameters (internet access ability). Devices compare their network information parameters, and the device with better network capability (e.g., internet access ability) is selected as group owner. This parameter change transforms the random selection process into a capability-based selection, improving network connection efficiency while maintaining reliable connection establishment.
2Ease of operation
If preset random group owner intent values are used, then the determination process is simple, but it cannot adapt to specific network situations
Solution Approach 1:
The patent introduces dynamic adaptability by allowing devices to share and compare their current network information (internet access ability, network type, etc.) during the group owner determination process. Instead of using static random values, devices dynamically assess their network capabilities and adjust their group owner intent accordingly. The device with superior network situation adapts to become group owner, making the system adaptable to specific network environments while maintaining a relatively simple determination process through automated comparison.
3Productivity
If network information comparison is implemented for group owner determination, then connection efficiency improves, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where devices exchange network information (internet access ability, network type, etc.) with each other during the connection process. Each device receives feedback about the other's network capabilities and uses this information to determine the optimal group owner. This feedback loop enables efficient connection by ensuring the device with better network situation becomes group owner, while the complexity is managed through structured information exchange protocols rather than complex algorithms.

AI summary
The method for performing device-to-device communication by a first device according to the present invention comprises: a step of searching a second device that supports device-to-device communication; a step of receiving, from the found second device, second network information including information on whether or not the second device may access the Internet; and a step of determining either the first device or the second device as a group owner based on a first network information including on whether or not the first device may access the Internet and the second network information on the second device. The first device determines the second device as a group owner when the first network information indicates that the first device may not access the Internet.
