Entropy-Based Message Deduplication for Emergency Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency situations, mobile devices send redundant messages, leading to network congestion and delays in communicating important information due to limited resources and environmental factors, which can hinder effective incident response.
Innovation Solution
Mobile devices determine an entropy factor to identify redundant messages and send redundant bits instead, prioritizing new information transmission based on network and device conditions, breaking down messages into segments for improved communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant messages are sent to ensure communication reliability during emergencies, then message delivery reliability is improved, but network congestion increases and transmission delays occur
Solution Approach 1:
The patent extracts and removes redundant message content from transmissions. By analyzing message similarity and identifying duplicate information, the system extracts only the essential new information for transmission, thereby reducing network congestion while maintaining communication reliability during emergencies
Solution Approach 2:
The patent changes the parameter of message representation by transforming full redundant messages into compact indicators or difference codes. Instead of transmitting complete duplicate messages, the system transmits parameter-efficient representations that convey the same information with reduced data volume, improving network transmission efficiency
2Reliability
If multiple redundant messages are transmitted to overcome environmental interference, then communication reliability is improved, but loss of time increases due to network congestion
Solution Approach 1:
The patent uses copying by transmitting only the essential information content once, rather than multiple complete copies of redundant messages. The system identifies the core information that needs to be conveyed and transmits it in an optimized format, reducing transmission time while maintaining communication reliability
Solution Approach 2:
The patent segments messages into essential information components and redundant components. By separating and transmitting only the essential segments, the system reduces overall transmission time and network congestion while ensuring that critical information reaches the destination reliably
3Loss of information
If complete messages are sent repeatedly to ensure delivery, then information completeness is improved, but network resource consumption increases
Solution Approach 1:
The patent inverts the traditional approach by not transmitting complete messages repeatedly, but rather transmitting minimal essential information that represents the complete message content. This inversion reduces network resource consumption while maintaining information completeness through efficient encoding and selection of critical data elements

AI summary
An electronic device may detect a message request to send one or more redundant messages to a response network. The one or more messages may contain information previously sent from the electronic device to the response network. The electronic device may determine an entropy factor corresponding to the relatedness of the one or more messages to previously sent messages, and the electronic device may send one or more redundant bits in the place of the one or more messages if the entropy factor is below a threshold value corresponding to network resources.
