Hybrid Node Sector Control for Wireless Network Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-hop wireless networks are susceptible to self-interference due to simultaneous transmission and reception operations across single-channel nodes, which hampers efficient communication.
Innovation Solution
The implementation of a wireless network system that includes first and second nodes configured for simultaneous transmission or reception, along with hybrid nodes whose sectors can be controllably selected to operate like either group of nodes, using time division duplexing (TDD) to mitigate interference and facilitate adaptive reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hybrid nodes are allowed to operate flexibly in multi-hop wireless networks, then adaptability and communication efficiency are improved, but self-interference between transmission and reception operations increases
Solution Approach 1:
The patent applies periodic action by implementing time-division duplexing (TDD) where hybrid nodes alternate between transmission and reception operations in periodic time slots. This resolves the self-interference problem by ensuring that a node does not transmit and receive simultaneously, while maintaining adaptability through dynamic slot allocation and hybrid node operation modes.
2Productivity
If hybrid nodes dynamically switch between transmission and reception modes, then communication efficiency is improved, but interference management complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where nodes monitor channel conditions, interference levels, and transmission success rates. This feedback information is used to dynamically adjust transmission power, select appropriate time slots, and determine optimal hybrid node configurations, thereby improving communication efficiency while managing interference complexity through data-driven decisions.
Solution Approach 2:
The patent applies dynamics by enabling hybrid nodes to dynamically switch between different operational modes (transmission-only, reception-only, or half-duplex) based on real-time network conditions. This dynamic adaptability allows the system to optimize communication efficiency while managing interference complexity through flexible, condition-based operation rather than static configurations.
