Frame Sorting Device for Wireless Sensor Network Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in sensor networks, such as those using the IEEE802.15.4 standard, face inefficiencies in throughput due to the intermittent reception timing of nodes, leading to increased time lags and decreased performance when transmitting frames, especially when frames for different destinations are not stored continuously in FIFO buffers.
Innovation Solution
An information communication apparatus with a request buffer, sorting device, frame generating device, and frame transmitting device that sorts and transmits frames based on determined transmission timings specific to each receiving node's intermittent reception periods, ensuring continuous transmission when possible and optimizing the order of frame transmission requests to maintain high throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If frames are transmitted using FIFO buffer in the order they are stored, then the transmission process is simple, but frames for the same destination cannot be transmitted continuously and throughput decreases
Solution Approach 1:
The patent applies preliminary action by sorting frames before transmission. The frame sorting device reorders frames in the buffer based on destination addresses and transmission timing information before they are transmitted. This preliminary sorting ensures that frames for the same destination are grouped together and transmitted continuously, enabling the frame continuation transmitting function to work effectively and improve throughput without complicating the transmission process
2Reliability
If the transmitting node searches for intermittent transmission timing information, then frames can be transmitted in accordance with receiving node timing, but the searching process takes a lot of time
Solution Approach 1:
The patent applies preliminary action by having the transmitting node acquire and store intermittent transmission timing information in advance. The timing information is obtained beforehand and stored in the frame transmission timing information storage unit, so that when frames need to be transmitted, the node can directly use the pre-acquired timing information without performing time-consuming search operations, thus ensuring reliable timing synchronization while minimizing transmission delay
3Adaptability or versatility
If frames with different destinations are stored continuously in FIFO buffer, then the buffer can participate in frame continuation transmitting function, but frames are not transmitted in optimal order and throughput decreases
Solution Approach 1:
The patent applies preliminary action by having the frame sorting device prepare frames in advance based on destination addresses and transmission timing. Before transmission occurs, the sorting device reorders frames so that those for the same destination are contiguous and ready for continuous transmission. This preliminary preparation enables the frame continuation transmitting function to work effectively while maintaining optimal throughput by eliminating unnecessary interruptions
