Device Communication Delay Estimation and Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods between devices are inefficient in optimizing hardware resource usage, as they require continuous monitoring for message arrival, which hinders the device's ability to perform other tasks and leads to suboptimal resource utilization.
Innovation Solution
A method where devices estimate delays in response times and adjust monitoring intervals based on thresholds, allowing the first device to free up resources and perform other tasks during estimated delay periods, while ensuring timely detection of messages through acknowledgment mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first device continuously monitors for message arrival, then message detection reliability is improved, but hardware resource utilization deteriorates
Solution Approach 1:
The patent implements periodic monitoring instead of continuous monitoring by establishing a time interval during which the first device does not monitor for message arrival. The monitoring is performed periodically at specific moments rather than continuously, allowing the device to perform other tasks during the intervals while still detecting messages reliably when they arrive.
2Productivity
If the first device performs other tasks during communication, then productivity is improved, but message detection capability deteriorates
Solution Approach 1:
The second device performs preliminary action by sending an acknowledgment of receipt to the first device before actually sending the message. This acknowledgment provides advance notice to the first device that a message is coming, allowing the first device to temporarily stop monitoring and perform other tasks, then resume monitoring at the appropriate time without missing the message.
3Use of energy by stationary object
If the monitoring interval is extended, then energy consumption is reduced, but response time deteriorates
Solution Approach 1:
The system uses feedback mechanisms where the second device sends an acknowledgment to inform the first device about the message arrival status. This feedback allows the first device to adjust its monitoring strategy dynamically - extending the interval when no messages are expected (saving energy) while ensuring monitoring resumes timely when messages are coming (maintaining response time).

AI summary
The invention relates to a method which includes the following steps: the first device (102) sends (202) a request (Rq) to the second device (104); the second device (104) receives (206) the request (Rq); the second device (104) sends (230) the first device (102) a response (R) to the request (Rq); the first device (102) receives (234) the response (R). The method also comprises the following step: the second device (104) estimates a period of time (D) during which it may send the response (R), as well as, in at least certain cases, the following steps: before sending the response (R), the second device (104) sends (212) an acknowledgement of receipt (AR) to the first device (102), the acknowledgement of receipt (AR) including the estimated period of time (D); the first device (102) receives (216) the acknowledgement of receipt (AR); the first device (102) calculates a time interval (I) from the estimated period of time (D); and the first device (102) allows the time interval (I) to pass before starting to monitor (228) the arrival of messages to detect the arrival of the response (R).
