Short-Range Wireless Direct Data Transmission Without Relay Caching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In new short-range wireless communication systems, secondary data transmission through system management and scheduling nodes reduces data transmission rates and increases memory and energy consumption due to the need for caching and double transmission, which complicates device complexity and resource allocation.
Innovation Solution
A data transmission method where a first node sends a request to a management node for data transmission authority, receives physical layer information to establish a direct connection with a second node, and transmits data based on this authority, allowing direct data transfer without caching, thus improving efficiency and reducing overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data transmission is performed through a management node as a bridge, then system management and scheduling are achieved, but data transmission rate decreases due to secondary transmission
Solution Approach 1:
The patent implements dynamic data transmission paths by allowing nodes to switch between direct transmission and relay transmission through the management node. The system dynamically selects the optimal transmission path based on real-time conditions, enabling high-speed direct communication when possible while maintaining the ability to use the management node for controlled scenarios.
Solution Approach 2:
The patent segments the data transmission function into two independent modes: direct transmission between service nodes and relay transmission through the management node. This segmentation allows the system to choose the appropriate transmission mode for each data flow, avoiding the mandatory secondary transmission through the management node and thereby improving transmission rate.
2Productivity
If data is transmitted through a management node, then scheduling control is achieved, but memory consumption increases due to caching requirements
Solution Approach 1:
The patent extracts the data caching function from the management node and relocates it to the service nodes themselves. Service nodes maintain their own data buffers and can perform direct transmission without requiring the management node to cache and forward data, thereby reducing the management node's memory consumption while maintaining transmission efficiency.
3Productivity
If data is transmitted through a management node, then centralized control is achieved, but energy consumption increases due to double transmission
Solution Approach 1:
The patent implements dynamic path selection that switches between direct transmission and relay transmission based on system conditions. When direct transmission is feasible, the system uses it to avoid the energy-consuming double transmission through the management node, thereby reducing overall energy consumption while maintaining efficient data transmission.
Solution Approach 2:
The patent changes the transmission parameter from fixed relay transmission to variable direct/relay selection. By adjusting the transmission path parameter dynamically based on conditions such as node proximity, data priority, and system load, the system optimizes energy consumption by minimizing unnecessary transmissions through the management node.
4Reliability
If relay transmission through management node is used, then data transmission control is achieved, but transmission overhead increases
Solution Approach 1:
The patent segments the transmission control function into centralized management for path selection and decentralized execution for actual data transfer. The management node provides centralized control for high-reliability scenarios, while direct transmission between service nodes eliminates the time overhead of relay transmission for routine data flows.

AI summary
The present disclosure provides a data transmission method applied to a first node. The method includes sending a first request for transferring a data transmission to a management node, the first request being generated based on to-be-transmitted data; receiving physical layer information sent by the management node in response to the first request, and obtaining an authority to perform the data transmission with a second node, the physical layer information being used to establish a connection with the second node; and transmitting the to-be-transmitted data to the second node based on the authority.
