Proximity Discovery via Server-Assisted Short-Range Interface Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing proximity discovery technologies face limitations in accuracy and battery consumption, particularly in server-based schemes requiring frequent location updates and in short-range wireless communication schemes that keep interfaces active, leading to power waste and overhead issues, especially in congested areas or when dealing with malicious broadcasts.
Innovation Solution
An electronic device can remotely control a communication interface for proximity discovery using a pre-established communication network, activating it only when needed and deactivating it post-discovery, allowing for precise proximity detection with reduced power consumption by exchanging necessary information through a WAN and utilizing short-range interfaces based on shared data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If server-based proximity discovery schemes are used with frequent location updates, then positioning accuracy is improved, but battery consumption increases
Solution Approach 1:
The system implements periodic proximity discovery where the first electronic device periodically sends discovery requests to the second device through the server. This periodic action allows the devices to update their location information at intervals rather than continuously, maintaining positioning accuracy while reducing battery consumption compared to continuous monitoring.
2Reliability
If short-range wireless communication interfaces remain active for proximity discovery, then discovery capability is improved, but battery consumption increases
Solution Approach 1:
The system performs preliminary proximity determination using server-based location information before activating short-range wireless communication interfaces. The first device sends a proximity discovery request to the server, which determines if devices are adjacent based on location data. Only after confirming proximity through this preliminary action does the system activate the short-range interface, ensuring discovery capability while minimizing unnecessary power consumption.
Solution Approach 2:
The short-range wireless communication interface is activated periodically only when proximity is detected through server-based location information, rather than remaining continuously active. This periodic activation maintains discovery capability while significantly reducing battery consumption compared to continuous interface operation.
3Reliability
If short-range wireless communication interfaces remain active in congested areas, then proximity discovery capability is improved, but overhead increases
Solution Approach 1:
The system performs preliminary proximity assessment using server-based location information before activating short-range wireless communication. The server determines whether devices are adjacent based on their location data, and only then does the first device activate its short-range interface to communicate with the second device. This preliminary action filters out non-proximate devices, reducing overhead in congested areas while maintaining discovery capability for actual neighbors.
4Measurement precision
If location information is frequently reported to server, then positioning accuracy is improved, but data usage increases
Solution Approach 1:
The system implements periodic location reporting where the first device sends its location information to the server at defined intervals rather than continuously. This periodic reporting maintains positioning accuracy for proximity determination while significantly reducing data usage compared to continuous location updates.
