Peer-to-Peer Beacon Asymmetric Awareness Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, asymmetric awareness between peer wireless stations can lead to failed data communication sessions due to one station being aware of another but not reciprocally, resulting in inefficient resource usage and delays.
Innovation Solution
Implementing a method where wireless stations transmit beacons with a Bloom filter attribute containing their MAC address, allowing them to confirm mutual awareness by searching for their address in received beacons, and only initiating data communication if awareness is symmetric.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless stations transmit beacons continuously to maintain awareness of peers, then awareness reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic beacon transmission where wireless stations transmit beacons at regular intervals rather than continuously. This allows stations to maintain peer awareness while consuming energy only during transmission periods, resolving the contradiction between reliability and energy consumption.
Solution Approach 2:
The patent uses feedback mechanisms where stations check received beacons for their own MAC address to determine peer awareness status. This feedback loop enables stations to adjust their communication behavior based on actual awareness state, maintaining reliability while avoiding unnecessary continuous transmission.
2Speed
If wireless stations initiate data communication sessions without verifying mutual awareness, then connection establishment speed is improved, but communication reliability deteriorates
Solution Approach 1:
The patent performs preliminary awareness verification by checking for MAC addresses in received beacons before initiating data communication sessions. This preliminary check ensures mutual awareness is established beforehand, preventing failed communications while maintaining relatively fast connection establishment.
Solution Approach 2:
The patent prevents potential communication failures by proactively verifying mutual awareness before session initiation. This preliminary anti-action blocks asymmetric awareness scenarios from occurring, ensuring communication reliability without significant speed penalty.
3Reliability
If wireless stations verify mutual awareness by searching MAC addresses in received beacons, then communication reliability is improved, but processing time increases
Solution Approach 1:
The patent extracts only the essential MAC address information from beacon frames for awareness verification, rather than processing entire beacon payloads. This extraction approach maintains communication reliability by verifying peer presence while minimizing processing time through selective data extraction.
4Productivity
If wireless stations establish direct peer-to-peer communication without access point coordination, then communication efficiency is improved, but awareness asymmetry problems worsen
Solution Approach 1:
The patent implements self-service awareness verification where each wireless station independently checks for its own MAC address in received beacons from peers. This self-verification mechanism enables direct peer-to-peer communication efficiency while each station autonomously ensures awareness symmetry, eliminating the need for access point coordination.

AI summary
In some embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to techniques for devices (e.g., NAN devices and/or AWDL devices) to detect asymmetric awareness amongst peers.
