Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-scale network systems with numerous endpoint devices face challenges in managing radio transmissions due to high energy consumption and security threats, as well as user concerns about constant radio emissions.
Innovation Solution
A method and apparatus for managing radio transmissions in endpoint devices, where a device can be woken up by a secure message and only establish a connection via radio transmission if a valid secure command is received within a predetermined time, otherwise turning off transmissions to conserve energy and enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If constant radio transmissions are maintained to monitor and communicate with endpoint devices, then network monitoring capability is improved, but energy consumption increases significantly
Solution Approach 1:
The system implements periodic action by allowing endpoint devices to enter low-power sleep modes and only activating radio transmissions when wake-up messages are received. This transforms continuous monitoring into periodic monitoring, where devices wake up, perform necessary communications, and return to sleep, thereby maintaining network monitoring capability while dramatically reducing energy consumption.
2Ease of operation
If constant radio transmissions are used for communication with endpoint devices, then network communication capability is improved, but security threats increase
Solution Approach 1:
The system applies preliminary anti-action by implementing cryptographic validation of wake-up messages and commands before allowing radio transmissions to occur. This preemptive security measure ensures that only authenticated and authorized devices can initiate or respond to radio communications, thereby maintaining communication capability while preventing unauthorized access and security threats.
3Reliability
If endpoint devices continuously emit radio transmissions, then network connectivity is improved, but user comfort decreases due to health concerns and interference
Solution Approach 1:
The system reduces radio emission interference by implementing periodic communication patterns where endpoint devices remain in low-power states and only activate transmissions when necessary for network operations. This minimizes the duration and frequency of radio emissions, maintaining network connectivity while reducing exposure to electromagnetic radiation and potential interference.
4Use of energy by moving object
If wake-up messages are sent to endpoint devices, then energy consumption is reduced by allowing devices to sleep, but security validation complexity increases
Solution Approach 1:
The system implements preliminary action by pre-configuring cryptographic credentials and validation rules in endpoint devices before they enter sleep mode. When wake-up messages are received, devices can quickly validate the message authenticity using pre-loaded security parameters, thereby enabling energy-efficient sleep operation without requiring complex real-time security processing.

AI summary
A method for managing radio transmission in an endpoint device in a network includes: receiving, at a first endpoint device, a message requesting wake up of the first endpoint device; establishing a connection between the first endpoint device to a second endpoint device connected to the network; determining, at the first endpoint device, whether a secure command is received from the second endpoint device via the established connection within a predetermined period of time; and based on the received secure command, establishing a connection between the first endpoint device and the network via radio transmission, wherein the first endpoint device is configured to turn off radio transmission if the secure command is not received within the predetermined period of time.
