Proxy Device Sleep Mode Negotiation for IPv6 Energy Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IPv6-based communication devices face difficulties in transitioning smoothly between sleep mode and communication mode due to errors in setup processes, such as address and router information errors, leading to inconvenience and inefficiency in energy-saving methods.
Innovation Solution
A system where a host device and a proxy device collaborate to manage sleep mode through a proxy sleep request and reply, allowing the host device to enter sleep mode based on the proxy device's acceptance and maintaining a minimum basic setup for communication, thereby omitting unnecessary setup operations when switching to communication mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a communication device enters sleep mode to save energy, then power consumption is reduced, but communication setup errors occur (address, router information) causing inconvenience and requiring reconfiguration
Solution Approach 1:
The proxy device performs preliminary actions by maintaining a simplified communication setup (minimum basic setup including address and router information) during the host device's sleep mode. This preliminary maintenance prevents setup errors from occurring when the host device wakes up, eliminating the need for reconfiguration while maintaining energy savings.
Solution Approach 2:
The proxy device acts as an intermediary between the host device and the network. It assumes responsibility for maintaining communication setup parameters during the host device's sleep mode, mediating the conflict between energy saving and communication reliability. The proxy device handles network communication tasks that would otherwise need to be maintained by the host device.
2Loss of energy
If a communication device operates in sleep mode with minimal setup, then energy saving is improved, but transition smoothness and speed between modes deteriorates due to setup errors
Solution Approach 1:
The proxy device performs preliminary maintenance of communication setup parameters during the host device's sleep mode. By keeping the minimum basic setup active and updated in advance, the system eliminates setup errors and reconfiguration needs when transitioning back to communication mode, achieving both energy savings and fast transition.
3Ease of operation
If a proxy device maintains minimum basic setup during host sleep mode, then transition smoothness is improved, but proxy device energy consumption increases
Solution Approach 1:
The proxy device applies partial action by maintaining only the minimum basic setup (essential address and router information) rather than the full communication setup. This partial maintenance is sufficient to ensure smooth transition while minimizing the proxy device's energy consumption and operational overhead during the host device's sleep mode.

AI summary
A system for saving energy through control of a sleep mode, and a method of operating the system are provided. The energy-saving system may enable a proxy device to maintain a minimum basic setup necessary for a communication when a host device enters a sleep mode, and may omit an operation performed based on the basic setup when the host device switches to a communication mode, thereby enabling a smooth switch between the sleep mode and the communication mode.
