Data Transmission Reliability Using Expected Arrival Sequences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks face challenges in maintaining transmission reliability of data units, particularly for time-sensitive communications, where errors can lead to survival time violations due to consecutive data unit failures.
Innovation Solution
A method is implemented to determine the expected arrival sequence of data units and increase transmission reliability by retransmitting adjacent data units using higher reliability mechanisms or storing and retransmitting preceding data units if they fail to arrive as expected, thereby reducing the probability of consecutive delivery failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data units are transmitted over the network system, then data delivery is achieved, but transmission reliability deteriorates due to consecutive data unit failures
Solution Approach 1:
The system performs preliminary actions by retransmitting adjacent data units before they are potentially lost, and by storing preceding data units in advance. This proactive approach ensures that if a data unit fails to arrive, reliable delivery can still be achieved through previously prepared redundant transmissions.
Solution Approach 2:
The system dynamically changes transmission parameters by adjusting the retransmission behavior of adjacent data units based on the arrival status of expected data units. When a data unit is missing, the system modifies transmission parameters to retransmit adjacent units with higher reliability, thereby adapting to varying network conditions.
2Reliability
If retransmission of adjacent data units is performed, then transmission reliability is improved, but system complexity increases
Solution Approach 1:
The system implements feedback mechanisms by monitoring the arrival status of expected data units and using this information to trigger retransmission of adjacent data units. This feedback-driven approach allows the system to maintain high reliability while avoiding unnecessary retransmissions that would increase complexity.
Solution Approach 2:
The system performs self-service by automatically detecting missing data units and initiating retransmission of adjacent units without external intervention. This self-managing capability reduces the need for complex external control mechanisms while maintaining transmission reliability.
3Reliability
If higher reliability mechanisms are used for retransmission, then transmission reliability is improved, but transmission time increases
Solution Approach 1:
The system applies partial action by selectively retransmitting only adjacent data units that are identified as potentially problematic, rather than retransmitting all data units. This targeted approach achieves sufficient reliability improvement without the time penalty of comprehensive retransmission.
Solution Approach 2:
By performing retransmission of adjacent data units in advance before potential loss occurs, the system reduces the need for time-consuming retransmission operations after failures are detected, thereby minimizing transmission time while maintaining reliability.

AI summary
An apparatus comprising means for: determining at least one expected arrival sequence of one or more expected data units to be transmitted over at least one network system; determining if at least one of the one or more expected data units does not arrive for transmission over the at least one network system as expected; and if it is determined that at least one of the one or more expected data units does not arrive for transmission over the at least one network system as expected, increasing transmission reliability of one or more data units adjacent to at least one expected data unit that has not arrived for transmission over the at least one network system as expected.
