IoT Terminal Data Relay via Intermediary Node
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IoT systems, IoT devices face high power consumption due to the need to establish a connection with network devices to transmit data, which increases energy usage and signaling overheads.
Innovation Solution
A communication method where a first terminal device generates data including an identifier and sends it to a second terminal device without establishing a connection to the network device, allowing the second terminal device to report the data to the network device, thereby reducing power consumption and signaling processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the IoT device establishes a connection to the network device to transmit data, then the data transmission reliability is improved, but the power consumption increases
Solution Approach 1:
The patent introduces a second terminal device as an intermediary to relay data from the first terminal device to the network device. The first terminal device sends data to the second terminal device without establishing a direct connection to the network device, and the second terminal device forwards the data to the network device. This intermediary approach allows data transmission while avoiding the high power consumption associated with establishing and maintaining a direct connection to the network device.
2Reliability
If the IoT device establishes a connection to the network device to transmit data, then the data transmission success rate is improved, but the signaling overhead increases
Solution Approach 1:
The second terminal device acts as a mediator that handles the signaling overhead with the network device. The first terminal device only needs to establish a simple connection to the second terminal device, while the second terminal device manages the more complex signaling requirements with the network device. This division reduces the signaling overhead burden on the first terminal device while maintaining transmission success rate.
3Reliability
If the IoT device establishes a connection to the network device to transmit data, then the data transmission quality is improved, but the device complexity increases
Solution Approach 1:
The second terminal device serves as an intermediary that absorbs the complexity of connection management with the network device. The first terminal device only needs to implement simple connection establishment and data transmission to the second terminal device, while the second terminal device handles the more complex aspects of network device interaction. This reduces the device complexity burden on the first terminal device while maintaining transmission quality.
