Connectionless Short-Range Data Broadcasting with Priority Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication devices are limited by the number of simultaneous connections they can maintain, particularly with Bluetooth, and lack flexibility in data transmission size and urgency handling, necessitating improvements for seamless and efficient data dissemination.
Innovation Solution
A method for transmitting data items involves packetizing data into packets, broadcasting over a connectionless short-range radio frequency band, and employing priority scheduling based on urgency levels and timestamps, with optional frequency hopping and user authentication for secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional Bluetooth connections are used, then secure communication is established, but the number of simultaneous connections is limited to seven devices
Solution Approach 1:
The patent segments the communication approach into two distinct modes: connection-oriented communication for secure data transfer and connectionless broadcasting for wide-area dissemination. This segmentation allows the system to maintain security where needed while achieving broad connectivity through broadcasting to multiple unknown devices simultaneously
Solution Approach 2:
The patent introduces a broadcasting mechanism as an intermediary between the communication device and multiple receiver devices. Instead of establishing direct connections to each device, the system broadcasts data packets through a connectionless channel, allowing any number of devices within range to receive the information without requiring individual connection setup
2Reliability
If connection setup is performed for each device, then secure communication is established, but connection setup time is consumed
Solution Approach 1:
The patent performs preliminary actions by establishing a broadcasting capability that can reach multiple devices simultaneously without requiring individual connection setups. The system prepares data packets in advance and broadcasts them through a connectionless channel, eliminating the time-consuming handshake processes that would otherwise be required for each individual connection
3Adaptability or versatility
If data is broadcast to unknown devices, then accessibility to multiple devices is achieved, but connection management complexity increases
Solution Approach 1:
The patent extracts the connection management complexity from the broadcasting mechanism itself. By using a connectionless channel for broadcasting, the system removes the need for complex connection tracking and management when reaching unknown devices. The broadcasting infrastructure handles dissemination, while connection-oriented protocols are only engaged when specific devices need secure communication
4Speed
If priority scheduling based on urgency levels is implemented, then timely delivery of critical information is ensured, but data processing complexity increases
Solution Approach 1:
The patent applies local quality by assigning different treatment levels to different data packets based on their urgency characteristics. Critical packets with high urgency are prioritized for immediate transmission, while less urgent packets are transmitted at lower priority levels. This localized differentiation of treatment ensures timely delivery of critical information without requiring complete redesign of the entire data processing system
