Address Translator for IoT Sleep Mode Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The network communication system's high energy consumption does not align with modern environmental protection requirements, particularly in IoT and cloud computing applications, where devices often need to maintain connections even in low-power modes.
Innovation Solution
A communication method that employs an address translator to maintain network connections by sending a keeping-connection request before entering sleep mode, allowing the electronic device to reduce power consumption while keeping the connection channel active through the address translator and server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device maintains network connection continuously, then the network connectivity is preserved, but the energy consumption increases
Solution Approach 1:
The device sends a keeping-connection request before entering sleep mode to pre-establish the connection maintenance mechanism. This preliminary action ensures that when the device wakes up, the connection channel is already preserved and ready for immediate use, eliminating the need for continuous connection monitoring during sleep mode.
Solution Approach 2:
The address translator acts as an intermediary between the electronic device and the server. It receives the keeping-connection request from the device, maintains the connection channel on its own resources, and responds to the device when needed. This intermediary approach allows the device to conserve energy while the address translator handles connection maintenance in the background.
2Use of energy by moving object
If the electronic device enters sleep mode to reduce power consumption, then energy usage decreases, but the network connection may be interrupted
Solution Approach 1:
Before transitioning to sleep mode, the device sends a keeping-connection request to the address translator. This preliminary action sets up the connection preservation mechanism in advance, ensuring that the connection channel remains active even when the device is in low-power state. The address translator maintains the channel using its own resources, so when the device wakes up, connectivity is immediately restored without interruption.
3Reliability
If traditional connection maintenance methods are used, then connection reliability is ensured, but memory usage and development cost increase
Solution Approach 1:
The connection maintenance functionality is extracted from the electronic device and relocated to the address translator. Instead of requiring the device to continuously monitor and maintain connections (which would consume device memory and processing resources), this function is taken out and handled by the address translator using its own resources. The device simply sends periodic keeping-connection requests, significantly reducing its memory and computational burden.
Solution Approach 2:
The address translator serves as an intermediary that assumes the burden of connection maintenance. It stores connection information, manages connection channels, and handles the complex logic of maintaining connections during device sleep modes. This intermediary approach allows the electronic device to use minimal memory while relying on the address translator's resources for reliable connection management.

AI summary
A communication method for keeping network connection of an electronic device in a sleep mode includes connecting an address translator to an electronic device via a local network, connecting the address translator to a server via an internet network, providing a connection channel between the electronic device and the server by using the address translator, sending a first keeping-connection request from the electronic device to the address translator before the electronic device gets into a sleep mode, and keeping freely flowing of the connection channel according to the first keeping-connection request by using the address translator when the electronic device is in the sleep mode.
