Network Master Node Power Save Control via Administrative Role Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home networks face high energy consumption due to network master nodes performing administrative functions even when not needed, making it difficult to enter power management modes, and existing systems may not optimally promote qualified slave nodes to master roles, leading to inefficient energy use and potential network loss.
Innovation Solution
A method to transfer network administrative functions from a master device to a slave device, allowing the master node to enter a power management state while sending necessary data to a slave node to assume the administrative role, thereby minimizing total power consumption and ensuring optimal network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the network master node enters power management mode to reduce energy consumption, then energy efficiency is improved, but network administrative functions cannot be performed
Solution Approach 1:
The patent extracts the network administrative master node function from the power-consuming device. When a device enters power management mode, its master node responsibilities are transferred to another device on the network, allowing the original device to conserve energy while network administration continues through the transferred function.
Solution Approach 2:
The patent introduces another device on the network as an intermediary to assume the master node function. This intermediary device takes over network administrative responsibilities when the original master node enters power management mode, enabling both energy conservation and continued network functionality.
2Reliability
If any slave node is promoted to master role to ensure network continuity, then network reliability is improved, but network performance may deteriorate due to suboptimal master selection
Solution Approach 1:
The patent implements a feedback mechanism where devices provide capability information to the network, and the system uses this feedback to select the most suitable device for master node promotion. This ensures that when a master node needs to be promoted, the selection is based on actual device capabilities rather than arbitrary choice.
Solution Approach 2:
The patent changes the selection parameter from arbitrary or first-available to capability-based selection. By evaluating device parameters such as processing power, memory, and other relevant capabilities, the system identifies the optimal candidate for master node promotion, thereby maintaining network performance while ensuring continuity.
3Reliability
If the master node remains active to perform administrative functions, then network administration is maintained, but energy consumption increases
Solution Approach 1:
The patent makes the master node function dynamic rather than static. The master node role can be transferred between devices based on power management needs and device capabilities. This dynamic approach allows the network to optimize energy consumption while maintaining administrative functionality through the ability to relocate the master node role.

AI summary
A method, in accordance with one embodiment, of managing power consumption in a network, comprising receiving an instruction for a first device in an active power state and serving as a network master node to enter into a power management state, the network master node adapted to perform a network administrative function while in an active power state, the power management state having a lower power consumption than the active power state; sending data from the first device to a second device serving as a network slave node, the data enabling the second device to start performing the network administrative function while in an active power state; and placing the first device into the power management state after sending the data.
