Ad Hoc Network Node Route Redundancy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ad hoc networks used for IoT applications, the limited communication bandwidth due to the need for both detection and management data transmission leads to potential insufficiency in data collection, which can compromise network management and reliability.
Innovation Solution
The child nodes in the network estimate route redundancy based on communication quality with adjacent nodes and control the transmission amount of management data accordingly, prioritizing more data transmission when the communication route is at higher risk of failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmission amount of management data is increased to ensure network management reliability, then the network management quality is improved, but the communication bandwidth is consumed faster leading to potential insufficiency in data collection
Solution Approach 1:
The patent applies dynamics by making the transmission amount of management data adjustable rather than fixed. The first communication apparatus dynamically controls the transmission amount based on real-time route redundancy estimation, adapting to changing network conditions to balance network management reliability with data collection efficiency
Solution Approach 2:
The patent changes the parameter of transmission amount based on route redundancy. By estimating the number of alternative routes and adjusting the management data transmission volume accordingly, the system optimizes bandwidth utilization while maintaining network management quality
2Productivity
If the transmission amount of management data is reduced to preserve communication bandwidth for detection data, then data collection efficiency is improved, but network management quality may deteriorate
Solution Approach 1:
The patent implements feedback by continuously estimating route redundancy and using this information to adjust management data transmission. The first communication apparatus monitors network conditions and adapts transmission levels, ensuring network management quality is maintained while preserving bandwidth for detection data
3Productivity
If route redundancy estimation and dynamic transmission control are implemented, then bandwidth utilization is optimized, but device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the first communication apparatus to autonomously estimate route redundancy and control its own transmission amount. The device performs self-adjustment based on network conditions without requiring external control, optimizing bandwidth utilization while managing complexity internally
