Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing wireless communication networks, low-power transmitters have a short range, leading to increased network traffic as messages are relayed multiple times through multiple gateway devices, causing redundancy and inefficiency.
Innovation Solution
A gateway communication device system that determines a reception quality indicator for each message, designates a master and backup gateway device based on reception quality, and prioritizes message transmission to reduce redundancy and enhance dependability without significantly increasing network traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple gateway devices receive and relay messages from low-power transmitters, then message delivery reliability is improved, but network traffic increases due to redundant transmissions
Solution Approach 1:
The patent segments the gateway device roles into master and slave gateways. The master gateway is responsible for relaying messages to the final destination, while slave gateways only forward messages to the master. This segmentation eliminates redundant transmissions by assigning specific relay responsibilities, thereby reducing network traffic while maintaining reliable message delivery through the master gateway.
2Adaptability or versatility
If gateway devices relay messages multiple times through the network, then message delivery coverage is improved, but transmission efficiency deteriorates
Solution Approach 1:
The patent divides gateway functions into master and slave roles to optimize the relay process. Slave gateways provide extended coverage by receiving messages from low-power transmitters and forwarding them to the master gateway, which then relays to the final destination. This segmentation ensures broad coverage while maintaining high transmission efficiency by eliminating redundant relays.
Solution Approach 2:
The master gateway acts as an intermediary between slave gateways and the final destination. Slave gateways transmit messages to the master, which then handles the final relay to the target device. This intermediary role ensures efficient message routing with a single relay to the destination, improving transmission efficiency while maintaining extended coverage through slave gateways.
3Reliability
If all gateway devices transmit messages to the recipient, then message delivery reliability is improved, but network congestion increases
Solution Approach 1:
The patent segments gateway responsibilities into master and slave roles. The master gateway is the sole device responsible for transmitting messages to the final recipient, while slave gateways only forward messages to the master. This segmentation eliminates redundant transmissions to the destination, reducing network congestion while maintaining reliable delivery through the master gateway's dedicated transmission role.

AI summary
The gateway communication device for wireless communication networks receives messages from a low-power transmitter and communicates with a network. In a system comprising several gateway devices for a low-power transmitter, a master gateway device is defined. Definition of a master gateway device is based on reception quality indicators of the gateway devices situated in said reception zone of messages transmitted by said low-power transmitter. The gateway device having the highest reception quality indicator is selected to be said master gateway device. The communication method also defines a master gateway device in the same way. The master gateway device then selects a backup gateway device to store link tables and in certain cases to act in the place of the master.
