Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless personal area networks, the absence of an FFD hinders flexible communication network formation and leads to power wastage due to constant device standby requirements for synchronization and data transmission/reception.
Innovation Solution
A method for data transmission/reception between nodes that involves periodic standby operations, where nodes detect each other and exchange notice information to synchronize data transmission timing, allowing intermittent standby and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nodes perform constant standby operation to enable data transmission/reception without FFD, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic standby operations where nodes alternately wake up to check for data transmission opportunities and return to sleep mode. Nodes perform standby operations at specific intervals, detecting notice information during wake periods and extending sleep mode during inactive periods, thereby reducing power consumption while maintaining communication reliability.
2Use of energy by moving object
If nodes perform intermittent standby operation to reduce power consumption, then power efficiency is improved, but communication reliability deteriorates due to synchronization issues
Solution Approach 1:
The patent uses notice information transmitted before actual data transmission to preliminarily inform nodes of upcoming data transmission timing. Nodes wake up in advance to receive and process notice information, then synchronize their standby operations accordingly. This preliminary notification mechanism ensures that nodes are ready to communicate when needed, maintaining reliability while enabling intermittent standby for power efficiency.
3Reliability
If FFD is present to provide centralized synchronization and management, then network coordination is improved, but device complexity increases
Solution Approach 1:
The patent extracts the essential synchronization function from the FFD by using notice information that carries timing data. Instead of requiring a full FFD with participation approval and superframe defining functions, the system only needs to transmit notice information containing data transmission timing. This extracts the core synchronization capability while eliminating the complexity of full FFD functionality.
4Speed
If nodes constantly monitor for data transmission opportunities, then data transmission responsiveness is improved, but power waste increases
Solution Approach 1:
The patent implements periodic monitoring where nodes wake up at specific intervals to check for notice information and data transmission opportunities, then return to sleep mode. This periodic action maintains data transmission responsiveness by ensuring nodes are periodically available to receive notices and transmit data, while significantly reducing power waste compared to constant monitoring.
