Broker Device Wireless Connection Information Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RF communication protocols for battery-powered devices are power-intensive, posing challenges for extending battery life, as they consume significant power during wireless data communication.
Innovation Solution
A broker device maintains and provides wireless connection information, including channel details, to enable direct wireless communication between devices, reducing the need for power-intensive protocols by allowing devices to communicate via pre-specified subsets of channels or sub-channels, such as those defined by the 802.11 standards, and facilitating direct Wi-Fi Direct connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RF communication protocols are used for wireless data communication, then inter-device communication capability is improved, but power consumption increases
Solution Approach 1:
The broker device performs preliminary actions by maintaining a registry of wireless devices and their connection information (channels, frequencies, SSIDs) in advance. When a device needs to communicate, the broker provides pre-configured connection parameters, eliminating the need for power-intensive real-time scanning and authentication protocols.
Solution Approach 2:
The broker device acts as an intermediary between wireless devices, centralizing the management of connection information. Instead of devices performing complex peer-to-peer discovery and authentication (which consumes power), they query the broker for pre-configured connection parameters, significantly reducing their power consumption while maintaining communication capability.
2Reliability
If standard RF communication protocols are employed, then communication reliability is improved, but battery life deteriorates
Solution Approach 1:
Connection parameters including channels, frequencies, and authentication credentials are pre-configured and stored in the broker device before communication occurs. This preliminary setup ensures reliable communication while allowing battery-powered devices to remain in low-power states, querying the broker only when needed rather than continuously scanning.
Solution Approach 2:
The broker device maintains its own registry and connection information autonomously. When queried by a device, it provides the necessary connection parameters without requiring the querying device to perform power-intensive discovery protocols, thus extending battery life while maintaining communication reliability.
3Ease of operation
If devices perform independent wireless discovery and connection, then communication autonomy is improved, but power consumption increases
Solution Approach 1:
The broker device serves as a central intermediary that maintains the registry of all wireless devices and their connection parameters. Devices can autonomously initiate communication by querying the broker for connection information, achieving operational autonomy without the power consumption of traditional discovery protocols. The broker handles the complex lookup and parameter provision centrally.
