Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wi-Fi P2P connections face delays and inefficiencies when a new device attempts to connect to a group client, requiring additional authentication processes that hinder seamless short-range communication.
Innovation Solution
An electronic device system and method that enables efficient short-range communication connections by transmitting signals to induce connections between devices, allowing a new device to connect directly to a group owner through a group client, optimizing the connection process within the Wi-Fi Direct standard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a new device attempts to connect to a group client in Wi-Fi P2P, then the connection request can be initiated, but additional authentication processes are required causing connection delay
Solution Approach 1:
The group client acts as an intermediary between the new device and the group owner. When a connection request is received, the group client forwards it to the group owner for authentication, and relays the response back. This mediator approach allows the new device to initiate connections to any device in the group without requiring direct authentication with the group owner, streamlining the connection process while maintaining security.
2Speed
If direct connection authentication is implemented between new device and group client, then connection speed improves, but security and protocol compliance deteriorate
Solution Approach 1:
The group client serves as a trusted intermediary that forwards connection requests to the group owner for authentication. This maintains Wi-Fi Direct protocol compliance where the group owner controls authentication, while enabling efficient connections to group clients through the relay mechanism. The group client can then establish direct connections with authenticated devices.
Solution Approach 2:
The system performs preliminary authentication through the group owner before establishing direct connections. By authenticating the new device through the group owner first, the system ensures protocol compliance and security are established in advance, allowing subsequent direct connections to proceed without additional authentication overhead.
3Reliability
If additional authentication processes are required for connecting to group clients, then security is maintained, but connection efficiency and usability deteriorate
Solution Approach 1:
The group client acts as a mediator that receives connection requests from new devices and forwards them to the group owner for authentication. This intermediary mechanism maintains security by ensuring the group owner validates all connection requests, while improving efficiency by enabling direct connection establishment once authenticated, eliminating the need for repeated authentication handshakes.
4Reliability
If Wi-Fi Direct protocol is strictly followed for all connections, then protocol compliance is maintained, but connection flexibility and ease of use deteriorate
Solution Approach 1:
The group client serves as an intermediary that implements a flexible connection initiation mechanism while maintaining Wi-Fi Direct protocol compliance. New devices can request connections to any group member through the group client, which forwards requests to the group owner for authentication. This provides connection flexibility similar to Bluetooth while ensuring Wi-Fi Direct security and protocol requirements are met.
