Serial Device-to-Device Content Sharing Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where multiple mobile device users attempt to download or watch the same video content at an event, existing methods either use separate network resources or a common channel, leading to inefficient use of network capacity and potential degradation of network performance, which negatively impacts the user experience due to inadequate power and modulation adjustments based on individual user locations and connections.
Innovation Solution
A method and system that serially share content using an event protocol, where user devices with suitable RF signal conditions synchronize and share content with neighboring devices requesting the same content, optimizing network capacity by transmitting from one device to another in a predetermined distance, repeating the process to deliver content efficiently across successive devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each user uses separate network resources to download data, then user experience is maintained, but network capacity is wasted due to redundant transmissions
Solution Approach 1:
The patent implements device-to-device content sharing where users who have already downloaded content act as local servers, copying the content to neighboring devices within communication range. This eliminates redundant network transmissions while maintaining user access to event content, directly resolving the contradiction between preserving user experience and conserving network capacity.
2Loss of energy
If data is sent over a common channel, then network capacity is preserved, but user experience degrades due to inability to adjust power and modulation based on individual user conditions
Solution Approach 1:
The patent enables each user device to independently control transmission power and modulation parameters when sharing content with neighbors. Each device adapts its transmission characteristics based on its specific RF conditions and distance to receiving devices, providing localized optimization that common channel transmission cannot achieve. This resolves the contradiction by maintaining network capacity efficiency while restoring individualized transmission control.
3Loss of energy
If content is shared serially between user devices, then network capacity is optimized, but system complexity increases due to synchronization requirements
Solution Approach 1:
The patent implements an event protocol where user devices autonomously perform synchronization and content sharing without requiring complex centralized coordination. Each device independently identifies neighbors, establishes connections, and transfers content based on simple criteria like proximity and content availability. This self-organizing approach achieves serial content sharing and network capacity optimization while minimizing system complexity through decentralized, rule-based interactions.

AI summary
Methods and systems for preserving network capacity by successively sharing content serially using an event protocol are provided. The method begins with monitoring the RF signal conditions for user devices at an event. A first user device with RF signal conditions above a threshold is identified. A second user device within a predetermined distance from the first user device and is within predetermined RF signal conditions is also identified. The second user device is requesting a download of the same content as the first device. The first and second user devices are synchronized using an event protocol. The event protocol may automatically perform the synchronization and may use a handshaking protocol as part of the synchronization process. Once the event synchronization is complete the first device transmits the content to the second device. The synchronizing may be repeated with successive user devices to serially deliver the common content to the successive user devices at the event.
