IoT Data Forwarding via Target Terminal Group Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication protocols, sending data to multiple IoT devices results in resource wastage as data is sent to each terminal individually, rather than efficiently forwarding it within a group.
Innovation Solution
A data transmission method where a network device sends data to a target terminal, which then forwards it to a first device group, utilizing specific transmission resources and indication information to optimize data forwarding within the group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If data is sent to each terminal individually in existing protocol, then each terminal can receive the data, but resource wastage occurs due to repeated transmission
Solution Approach 1:
The patent merges multiple individual data transmissions into a single group transmission. The network device sends data to a target terminal that then forwards it to multiple terminals in a device group, combining what would have been separate transmission operations into one efficient group operation, thereby reducing resource wastage while maintaining effective data delivery to all intended recipients
2Loss of energy
If data is sent to a target terminal for forwarding to device group, then resource efficiency improves, but system complexity increases due to forwarding mechanism
Solution Approach 1:
The patent introduces a target terminal as an intermediary between the network device and the device group terminals. This intermediary receives data from the network device and forwards it to multiple terminals in the group, simplifying the overall system architecture by using a single relay point rather than requiring complex multi-point transmission coordination, thus improving resource efficiency while keeping the forwarding mechanism manageable
