Network Relay Device Wake-Up Signal Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network systems face challenges in reducing power consumption during device-to-device communications, as relay devices often remain in an active state unnecessarily, leading to increased energy usage.
Innovation Solution
A transmission method where a wake up signal, path information, and main data signal are sequentially transmitted, allowing relay devices to activate only when necessary, reducing power consumption by activating circuits only when required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay devices remain in active state to ensure continuous data transmission capability, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The transmission device transmits a wake-up signal before the main data signal to preliminarily activate relay devices. This preliminary action ensures that relay devices are in an active state when needed, maintaining communication reliability while avoiding unnecessary power consumption during idle periods. The wake-up signal is transmitted only when data transmission is required, allowing relay devices to transition from standby to active state on demand.
Solution Approach 2:
The system dynamically adjusts the operational state of relay devices based on transmission requirements. Relay devices can transition between standby and active states according to whether a wake-up signal is received, enabling the system to adapt power consumption levels to actual communication needs rather than maintaining a fixed active state.
2Use of energy by moving object
If relay devices are activated only when necessary to reduce power consumption, then energy efficiency is improved, but transmission delay increases
Solution Approach 1:
The wake-up signal is transmitted as a preliminary action before the main data signal, allowing relay devices to activate in advance. This preliminary activation minimizes the time relay devices spend in standby state during data transmission, reducing overall transmission delay while still maintaining low power consumption during idle periods.
Solution Approach 2:
By transmitting the wake-up signal continuously or periodically before data transmission begins, the system ensures that relay devices are ready for immediate data transmission. This continuous preparation reduces the activation time and ensures smooth transition from standby to active state, minimizing transmission delay.
3Reliability
If wake-up signal is transmitted continuously to ensure reliable reception, then reception reliability is improved, but energy consumption increases
Solution Approach 1:
The wake-up signal is transmitted periodically or in intervals rather than continuously. This periodic transmission maintains reception reliability by ensuring relay devices are activated before data transmission, while significantly reducing energy consumption compared to continuous transmission. The timing intervals are optimized to balance reliability and energy efficiency.

AI summary
The present invention allows a reduction in power consumed by communications between devices over a network.A transmission-side device transmits a signal including a wake up signal, path information, and a main data signal in this order to the following relay device (switch/router). The relay device activates a circuit in a standby state on a path on the basis of the wake up signal and the path information.
