Multi-Hop Wireless Traffic Control via Dynamic Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies face difficulties in preventing congestion of communication data in multi-hop networks, particularly due to increased packet losses and disturbances during wireless relays, especially when data is continuously transmitted from child nodes to parent nodes.
Innovation Solution
The communication device includes processing circuitry that acquires and changes communication parameters to reduce traffic volume per unit time by generating control commands based on detected packet losses and error corrections, thereby adjusting bit rates and frame rates to manage traffic effectively across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is continuously transmitted from child nodes to parent nodes in a multi-hop network, then communication productivity is improved, but packet loss and network congestion increase
Solution Approach 1:
The patent implements dynamic traffic volume adjustment by monitoring packet loss rates and continuously adapting communication parameters. The system changes transmission characteristics in real-time based on network conditions, transforming static transmission into a dynamic adaptive process that resolves the contradiction between continuous transmission and packet loss prevention
Solution Approach 2:
The patent establishes a feedback mechanism where packet loss detection triggers traffic volume reduction commands that propagate through the network. This feedback loop allows the system to respond to congestion conditions and adjust transmission rates accordingly, preventing packet loss while maintaining communication productivity
2Speed
If traffic volume per unit time is increased to improve communication speed, then transmission speed is improved, but network congestion and packet loss worsen
Solution Approach 1:
The patent changes communication parameters dynamically by adjusting traffic volume per unit time based on network conditions. When congestion is detected, the system modifies transmission parameters to reduce traffic volume, thereby eliminating congestion while adapting transmission speed to current network capacity
3Reliability
If error correcting packets are transmitted later than video data to recover burst loss, then data recovery capability is improved, but communication complexity increases
Solution Approach 1:
The patent extracts the error correction function from the main data transmission flow by sending error correcting packets separately after video data. This separation allows the system to maintain simple video data transmission while adding recovery capability through distinct correction packets, managing complexity by dividing functions into separate transmission streams
