Service Distribution via Peer Device Trajectory Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless and wired communication systems, there is a challenge in distributing media content and services efficiently, particularly for devices with less desirable link signal qualities or those that are offline during updates, as traditional unicast and multicast methods may not adequately address network resource utilization and bandwidth congestion.
Innovation Solution
A system that uses location information from communication devices to determine trajectories and identify peer-to-peer communication ranges, allowing for the delegation of services through secondary communication devices acting as 'couriers' to offload network resources and alleviate traffic congestion by delivering content when devices are in proximity, thereby optimizing network resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional unicast or multicast methods are used to distribute content, then network infrastructure can deliver services, but network bandwidth is consumed and congestion occurs
Solution Approach 1:
The patent introduces peer devices as intermediary couriers to transfer content between the content source and target devices. These peer devices temporarily store and forward content, acting as mediators that reduce direct network traffic. The system identifies suitable peer devices based on trajectory predictions and uses them to deliver content updates, thereby reducing network bandwidth consumption while maintaining reliable service delivery.
Solution Approach 2:
The content distribution process is segmented into multiple hops through peer devices rather than direct network transmission. The journey from content source to target is divided into segments, with each peer device handling a portion of the transfer. This segmentation allows content to be delivered through local device-to-device communication, reducing the load on network infrastructure.
2Adaptability or versatility
If content is distributed through network infrastructure, then services can be provided, but devices with poor link signal quality receive less desirable service
Solution Approach 1:
Peer devices act as intermediaries that can deliver content directly to target devices with poor signal quality, bypassing the problematic network link. By using device-to-device communication for the final delivery hop, the system overcomes network infrastructure limitations and provides reliable service to devices in poor signal conditions.
Solution Approach 2:
The system employs different delivery mechanisms based on local conditions: network infrastructure for devices with good connectivity, and direct device-to-device peer-to-peer transfer for devices with poor signal quality. This localized adaptation of delivery method ensures optimal service quality for each device based on its specific communication conditions.
3Extent of automation
If content updates are distributed centrally, then service control is maintained, but devices that are offline when updates are available miss the updates
Solution Approach 1:
The system performs preliminary actions by predicting device trajectories and identifying potential peer couriers in advance. Before content needs to be delivered, the system pre-identifies suitable peer devices along the target device's expected path and prepares them to act as couriers. This preliminary preparation ensures that when the target device becomes available, content can be delivered immediately without waiting for centralized coordination at that moment.
Solution Approach 2:
The system enables a form of self-service where peer devices autonomously participate in content distribution based on their predicted trajectories and proximity to target devices. Devices that will be in proximity to targets are automatically selected as couriers without requiring real-time centralized coordination, allowing the network to adapt dynamically to device availability while maintaining overall service control.
4Productivity
If more network resources are allocated for content distribution, then service delivery improves, but network congestion increases
Solution Approach 1:
Peer devices serve as intermediaries that transfer content locally without requiring continuous network infrastructure involvement. This mediation shifts traffic from network channels to direct device-to-device communication channels, reducing network traffic volume while maintaining or improving distribution efficiency through localized high-speed transfers.
Solution Approach 2:
The system adds a spatial dimension to content distribution by utilizing the physical proximity and movement of devices in three-dimensional space. Instead of relying solely on network infrastructure dimensions, the system exploits the spatial-temporal dimension of device trajectories and proximity, enabling content to be delivered through physical proximity-based peer-to-peer links that bypass network congestion.
