Adaptive Handshaking for Wireless Node Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information transmission systems, such as sensor networks, waste power and time due to unnecessary handshaking signals when transmitting data to nodes that do not require power-saving handshaking, especially in multi-hop networks with both battery-powered and externally powered nodes.
Innovation Solution
An information transmitting device that selectively uses power-saving or normal transmission modes based on stored information about destination nodes, avoiding unnecessary handshaking signals by determining whether power-saving handshaking is required, thus reducing power consumption and transmission delays.

Engineering Contradiction Analysis
1Reliability
If the RICER handshaking scheme is always employed to ensure receiving nodes are ready, then reliability of information transmission is improved, but power consumption increases and transmission delays occur even when unnecessary
Solution Approach 1:
The patent applies dynamics by making the handshaking mechanism adjustable rather than fixed. The transmitting node dynamically switches between two transmission modes: a first mode that includes handshaking for reliable communication with battery-powered nodes, and a second mode that excludes handshaking for efficient communication with externally-powered nodes. This dynamic adaptation resolves the contradiction by enabling reliability when needed while avoiding unnecessary power consumption when not needed.
Solution Approach 2:
The patent changes the parameter of transmission mode based on the power source type of the destination node. The transmitting node determines whether the destination is battery-powered or externally-powered, and accordingly changes the transmission parameters: using handshaking protocols for battery-powered nodes and direct transmission for externally-powered nodes. This parameter change resolves the technical contradiction by optimizing the balance between reliability and power consumption based on actual conditions.

3Duration of action of stationary object
If power-saving transmission mode with handshaking is used for all destinations, then battery life is extended for battery-powered nodes, but power consumption increases and transmission efficiency decreases for externally-powered nodes
Solution Approach 1:
The patent applies dynamics by making the transmission mode adaptable to different destination node types. The transmitting node dynamically selects between power-saving mode with handshaking for battery-powered destinations and normal mode without handshaking for externally-powered destinations. This dynamic selection resolves the contradiction by extending battery life when communicating with battery-powered nodes while maintaining high transmission efficiency when communicating with externally-powered nodes.
Solution Approach 2:
The patent changes the transmission mode parameter based on the destination node's power source type. When the destination is battery-powered, the system uses power-saving mode with handshaking to extend battery life. When the destination is externally-powered, the system switches to normal mode without handshaking to maximize transmission efficiency. This parameter change resolves the technical contradiction by optimizing for battery life or transmission efficiency based on actual conditions.

AI summary
A network includes nodes that transmit information to each other. Some nodes operate intermittently; other nodes operate continuously. Information is transmitted to an intermittently operating node by a handshaking protocol in which the intermittently operating node indicates that it is ready to receive. Information is transmitted to a continuously operating node without such handshaking, thereby saving time and power. Each transmitting node has a memory storing information indicating which other nodes require handshaking.
