Prioritizing Discovered Device List by RSSI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In densely populated WPAN environments, existing technologies take time to present a user-friendly list of discoverable devices due to the sequential retrieval of friendly names, which can be cumbersome and inefficient.
Innovation Solution
A method that prioritizes the discovered device list based on Received Signal Strength Indication (RSSI), ordering devices from highest to lowest signal strength, allowing for quicker identification of closest devices and facilitating faster connection establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If devices are listed in order of discovery time (existing technology), then the list is simple to generate, but the user cannot quickly identify the desired device among many discovered devices
Solution Approach 1:
The patent retrieves friendly names for devices in advance, before the user needs to make a selection. By pre-populating the device list with friendly names obtained through sequential requests during the discovery process, the system eliminates the waiting time that would occur if names were retrieved only after the user initiated connection. This preliminary action ensures that when devices are displayed, their identifying names are already available, significantly improving selection efficiency.
2Ease of operation
If all discovered devices are presented to the user (existing technology), then complete device information is available, but the list becomes cumbersome and difficult to navigate in densely populated WPAN environments
Solution Approach 1:
The system performs preliminary actions during the device discovery process by obtaining friendly names early and maintaining them in memory. This allows the complete device list to be presented with full identifying information already in place, making navigation easier despite the large number of devices. The preliminary retrieval of names prevents the need for users to wait during browsing, improving navigability even when many devices are present.

AI summary
The described embodiments relate generally to methods, systems and computing devices, including at least a mobile device, for ordering a discovered device list according to a Received Signal Strength Indication (RSSI) of each device in the discovered device list. Thus, the discovered device list has at the top of the list the device that has the highest RSSI, with the remaining devices in the discovered device list presented in descending order of RSSI.
