Dynamic PLCP Header Selection for Wireless Transmission Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in autonomous distributed wireless networks, excessive transmission suppression occurs as the number of information processing apparatuses increases, leading to deteriorated transmission efficiency due to the carrier sense mechanism, which fails to effectively manage the ratio between desired and interference wave powers, resulting in potential transmission errors.
Innovation Solution
The implementation of an electronic device that selects a Physical Layer Convergence Protocol (PLCP) header format and appends it to physical layer packets for transmission, allowing for dynamic adjustment of carrier sense detection thresholds based on communication quality, enabling efficient use of wireless resources by distinguishing between short-distance and long-distance physical headers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If carrier sense level threshold is increased to allow more transmissions, then transmission efficiency improves, but transmission errors occur when signal-to-interference ratio is unfavorable
Solution Approach 1:
The patent implements dynamic adjustment of carrier sense detection thresholds based on communication quality conditions. The wireless communication apparatus changes the threshold value adaptively - using higher thresholds when signal-to-interference ratio is favorable to allow more transmissions, and lower thresholds when conditions are poor to prevent transmission errors. This dynamic parameter adjustment resolves the contradiction between transmission efficiency and reliability.
2Quantity of substance
If number of information processing apparatuses increases, then network capacity improves, but excessive transmission suppression occurs leading to deteriorated transmission efficiency
Solution Approach 1:
The patent changes the carrier sense detection threshold parameter dynamically based on the communication environment and number of active apparatuses. When many apparatuses are present causing excessive suppression, the threshold is adjusted to allow more transmissions. This parameter change enables the system to maintain high transmission efficiency even as network scale increases, resolving the contradiction between network capacity and transmission efficiency.
