Wireless Message Segmentation for Emergency Broadcasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency situations, existing communication and power infrastructure may be unavailable, making it difficult to rapidly and effectively broadcast critical information to the public and rescue teams, especially in areas with unique conditions, due to the limitations of communication networks and power supply during disasters.
Innovation Solution
A method utilizing existing wireless communication protocols, such as Bluetooth and Wi-Fi, to broadcast messages by identifying the maximum packet length, splitting messages into packets, and broadcasting them using identification features, allowing for robust and resilient information delivery through low-cost devices that can operate independently of the power grid and existing infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing communication networks and power infrastructure are used for broadcasting emergency information, then centralized control and wide coverage are achieved, but the system becomes vulnerable to infrastructure failure during disasters
Solution Approach 1:
The system segments the broadcasting function into independent wireless devices that operate autonomously without central infrastructure. Each device can independently broadcast emergency information using standard wireless protocols, eliminating single-point failures and infrastructure dependency while maintaining wide coverage through distributed deployment.
2Loss of information
If message size is increased to provide comprehensive emergency information, then information completeness is improved, but transmission reliability decreases due to packet loss and protocol limitations
Solution Approach 1:
The emergency information message is automatically segmented into multiple smaller packets that fit within standard wireless protocol limits. Each packet is transmitted independently, ensuring reliable delivery even in poor signal conditions. The receiving device reassembles the packets to reconstruct the complete emergency information, maintaining both completeness and transmission reliability.
3Adaptability or versatility
If specialized emergency broadcasting infrastructure is deployed, then location-aware notifications and rescue team support are improved, but cost and deployment complexity increase
Solution Approach 1:
The system uses universal wireless devices with standard communication protocols that can serve multiple functions: emergency information broadcasting, location awareness through GPS integration, and support for both general public and rescue team communications. This multi-functionality achieves specialized capabilities without requiring dedicated infrastructure, reducing both cost and deployment complexity.

AI summary
A method for broadcasting messages by means of identification features of existing wireless communication protocols includes identifying, for a received message, a maximum packet length to be broadcasted using a wireless protocol. The method further includes splitting the received message into two or more packets, wherein the length of each packet of the two or more packets does not exceed the identified maximum packet length. The method further includes broadcasting the two or more packets by means of an identification feature of the wireless protocol.
