Peer-to-Peer Data Transfer with Back-Office Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Short range wireless technologies require multiple passes and prolonged proximity for transferring large data, negatively impacting quality of service and user experience due to prolonged waiting times for complete data transfer.
Innovation Solution
A wireless network and method that enables peer-to-peer data transfer using short range wireless devices, where a first device sends a portion of content along with location information for the remaining portion, allowing immediate processing and retrieval from a server, even if the remaining portion is DRM-protected, facilitating rapid start of data usage without waiting for complete transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all content is transferred via peer-to-peer short range wireless technology, then data transfer completeness is ensured, but transfer time is excessively long and user experience deteriorates
Solution Approach 1:
The content is divided into two portions: a first portion transferred via peer-to-peer short range wireless technology and a second portion retrieved from a server. This segmentation allows the urgent first portion to be transferred quickly while the less time-critical second portion is obtained asynchronously, resolving the contradiction between complete data transfer and transfer time.
Solution Approach 2:
The system performs preliminary action by transferring the first portion of content and its location information before the complete content is available. The receiving device begins processing the first portion immediately while the second portion is retrieved in the background, eliminating the need to wait for complete transfer before starting use.
2Reliability
If multiple passes are used for complete data transfer, then data transfer completeness is achieved, but proximity duration requirement increases
Solution Approach 1:
The content transfer is segmented into a first portion transferred during brief proximity contact and a second portion retrieved from a server. This eliminates the need for prolonged proximity or multiple passes, as the critical first portion is transferred in a single brief interaction while the remainder is obtained asynchronously.
Solution Approach 2:
A server acts as an intermediary to store and provide the second portion of content. Instead of requiring direct peer-to-peer transfer of all content (which would need multiple passes), the server mediates the delivery of the remaining content, allowing the mobile devices to separate and eliminating the need for extended proximity.
3Reliability
If complete content is transferred before usage, then data integrity is ensured, but user experience and quality of service deteriorate due to waiting time
Solution Approach 1:
The system performs preliminary action by transferring and enabling use of the first portion of content before the complete content is available. The receiving device can immediately process and use the first portion while the second portion is retrieved in the background, eliminating idle waiting time and significantly improving user experience while maintaining eventual data integrity.
Solution Approach 2:
The system accepts partial action by allowing the user to use the first portion of content before complete transfer is finished. This partial usage is sufficient to provide immediate value to the user, with the understanding that the complete content will be available later, thus prioritizing user experience over complete data availability at the moment of transfer.
Data Source
AI summary
A method of data transfer using short range technology. An originating short range wireless technology enabled device wirelessly communicates a first portion of content to a destination short range wireless technology enabled device along with location information that enables retrieval of a remaining portion of the content from a back office location. The destination short range wireless technology enabled device processes the first portion of content. The remaining portion of the content may be retrieved for processing by the destination short range wireless technology enabled device before the completion of processing of the first portion of content.
