Wireless Data Transmission Optimization via Node Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face pressure due to limited spectrum resources, particularly in machine-type communications where small amounts of data with strong regularity patterns are transmitted, leading to inefficient use of channel resources.
Innovation Solution
A method and system for data transmission in wireless communication networks where a receiver node selects one transmitter node based on statistical conditions, such as data similarity or regularity patterns, and notifies other nodes to optimize data transmission, allowing some nodes to skip transmitting data if it matches the selected node's data, thereby reducing resource occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated transmission channel is established between every two adjacent transmitter nodes for frequent data transmission, then the data transmission reliability is improved, but the resource occupation of the communication channel increases
Solution Approach 1:
The patent merges multiple transmission channels into a shared pool that is dynamically allocated. Instead of establishing dedicated channels between each transmitter-receiver pair, the system creates a common transmission resource that multiple nodes can access when needed, reducing overall channel occupation while maintaining transmission reliability through on-demand allocation.
Solution Approach 2:
The patent implements dynamic channel allocation where transmission channels are established and released based on real-time data transmission needs. The system continuously monitors transmission frequency and adjusts channel allocation accordingly, creating channels only when data transmission is required and releasing them when not needed, thus optimizing both reliability and resource efficiency.
2Adaptability or versatility
If a transmission channel is re-established for each new data transmission request, then the adaptability to different data transmission needs is improved, but the overhead for the control plane increases
Solution Approach 1:
The patent performs preliminary actions by pre-establishing a shared transmission channel pool and pre-configuring transmission parameters before actual data transmission occurs. This allows the system to quickly allocate resources from the pre-prepared pool rather than establishing channels from scratch for each transmission request, reducing control plane overhead while maintaining adaptability.
Solution Approach 2:
The patent creates a universal transmission channel structure that can serve multiple transmitter nodes and multiple receiver nodes simultaneously. This multi-functional channel design allows a single channel resource to handle various data transmission requests from different node pairs, reducing the need to re-establish dedicated channels for each specific transmission scenario.
3Loss of time
If multiple transmitter nodes continuously report data to the receiver node, then the data freshness is improved, but the wireless resource occupation increases
Solution Approach 1:
The patent implements a self-service mechanism where transmitter nodes autonomously determine whether to transmit data based on local conditions and receiver feedback. Nodes monitor their own data changes and only initiate transmission when necessary, rather than continuously reporting. This self-service approach maintains data freshness by transmitting only when actual changes occur, significantly reducing wireless resource occupation.
Solution Approach 2:
The patent establishes a feedback mechanism where the receiver node provides acknowledgments and status information back to transmitter nodes. This feedback allows transmitters to adjust their transmission behavior based on receiver needs and current channel conditions, maintaining data freshness through targeted transmissions while optimizing wireless resource usage by avoiding redundant transmissions.
