Dynamic Pre-authorization for Wireless Collision Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks, hidden node collisions due to concurrent transmissions by devices out of direct communication range lead to performance degradation, increased latency, and reduced user experience, as existing solutions like pre-authorization messages incur overhead and reduce communication capacity.
Innovation Solution
A transmitting electronic device dynamically monitors performance metrics and selectively enables or disables pre-authorization messages based on thresholds, using request-to-send and clear-to-send messages to prevent collisions, thereby adapting to changing communication conditions and optimizing overhead and capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-authorization messages are used to prevent hidden node collisions, then collision protection is improved, but communication overhead increases and capacity decreases
Solution Approach 1:
The patent implements dynamic adaptation of pre-authorization message usage based on monitored performance metrics. The system transitions from static always-on collision protection to dynamic conditional usage, adjusting the level of protection based on actual network conditions and error rates observed in hidden node scenarios.
Solution Approach 2:
The system changes operational parameters by selectively enabling or disabling pre-authorization messages based on performance metric thresholds. When packet error rates exceed thresholds indicating hidden node problems, the system activates pre-authorization; when error rates are acceptable, it deactivates them, thereby optimizing the balance between reliability and productivity.
2Reliability
If pre-authorization messages are continuously used, then collision protection is maintained, but overhead and capacity impact worsens
Solution Approach 1:
The system employs periodic monitoring of performance metrics and selective activation of pre-authorization messages rather than continuous usage. This periodic assessment allows the system to maintain collision protection only when necessary, reducing time loss to overhead when the protection is not needed.
Solution Approach 2:
The patent extracts the pre-authorization mechanism from continuous operation and applies it selectively based on detected conditions. By taking out the overhead burden and applying it only when performance metrics indicate hidden node collision problems, the system reduces unnecessary time loss while maintaining protection when needed.
3Productivity
If pre-authorization messages are selectively enabled based on performance metrics, then overhead is reduced, but collision protection may be insufficient when conditions change
Solution Approach 1:
The system implements continuous feedback loops by monitoring performance metrics such as packet error rates and adjusting pre-authorization message usage accordingly. This feedback mechanism ensures that when network conditions deteriorate and hidden node collisions occur, the system detects the degradation and activates protection measures.
Solution Approach 2:
The system performs preliminary monitoring of performance metrics to detect conditions indicating hidden node problems before they cause significant degradation. By detecting early signs of collision issues through error rate monitoring, the system can activate pre-authorization messages in advance to prevent further performance deterioration.

AI summary
In order to maintain performance during wireless communication, a transmitting electronic device may selectively enable use of pre-authorization messages during communication with one or more receiving electronic devices. In particular, the transmitting electronic device may monitor a performance metric associated with the communication. If the performance metric is less than a threshold, the transmitting electronic device may selectively enable the use of the pre-authorization messages before communicating data to the one of the receiving electronic devices. Subsequently, the transmitting electronic device monitors a pre-authorization performance metric associated with the communication of the pre-authorization messages. If the pre-authorization performance metric is less than a pre-authorization threshold, the transmitting electronic device may selectively disable the use of the pre-authorization messages. Moreover, if the use of pre-authorization messages is disabled, the transmitting electronic device reverts to monitoring the performance metric.
