Solution Overview

Problem

Existing architectures for sharing resources between devices often rely on central servers, limiting direct device-to-device (D2D) resource sharing and control without the assistance of a central coordinating server.

Innovation Solution

The system enables D2D resource sharing by establishing a communication channel between devices, allowing a remote device to control local resources through credential management and resource aggregation, enabling direct control and virtualization of resources without a central server, using modules like D2D communication, credential management, and resource aggregation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a central server system is used for resource sharing, then resource allocation and control can be centralized and managed, but direct device-to-device resource sharing and control are limited

Engineering Contradiction:
Improveresource sharing capabilityVSAvoidsystem architecture
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the resource sharing functionality from the central server architecture and implements it directly between devices. The D2D communication module enables devices to share resources peer-to-peer without requiring central server mediation, thereby removing the architectural complexity while maintaining resource sharing capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a credential management module as an intermediary that enables secure direct communication between devices. This module handles authentication and authorization locally, allowing devices to verify each other's credentials and establish trusted connections without central server involvement.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If direct device-to-device communication is established, then resource sharing efficiency and flexibility improve, but security management and authorization become more challenging

Engineering Contradiction:
Improveresource sharing efficiencyVSAvoidsecurity management
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements preliminary security actions by establishing credential verification before resource sharing begins. The credential management module pre-authenticates devices and establishes authorization tokens, ensuring security protocols are in place before any resource access occurs, thus maintaining reliability while enabling direct communication.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent incorporates feedback mechanisms where devices continuously verify credentials and authorization status during resource sharing operations. The system monitors access permissions and can revoke or modify access rights based on ongoing verification, ensuring security is maintained dynamically throughout the resource sharing process.

Inventive Principle:
Principle #23Feedback

AI summary

Embodiments of techniques and systems associated with device-to-device (D2D) resource sharing are described. In some embodiments, a D2D communication channel between a first device and a second device is established and a sharing request is received at the first device, from the second device, including a credential identifying the second device. Data representative of a first resource locally available to the first device, but not locally available to the second device, is provided to the second device by the first device. Use of the first resource may be controlled in accordance with an instruction transmitted to the first device from the second device. Other embodiments may be described and/or claimed.
