Solution Overview

Problem

Existing wireless communication networks face challenges in efficiently utilizing excess resources due to limited coordination and incentivization mechanisms for peer-to-peer resource sharing, leading to suboptimal network performance and resource management.

Innovation Solution

Implementing a decentralized transaction ledger (blockchain) to track and incentivize resource sharing among devices, allowing devices to record and verify transactions for shared resources, thereby facilitating cooperative communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If resources are provisioned based on expected loads to provide desired service availability, then service reliability is improved, but resource utilization deteriorates

Engineering Contradiction:

Improveservice availabilityVSAvoidresource utilization

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent implements a self-service mechanism where wireless devices autonomously share and allocate excess resources to other devices in need. The distributed transaction ledger enables devices to self-manage resource transactions without centralized control, allowing dynamic resource allocation that improves utilization while maintaining service availability through peer-to-peer assistance.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system dynamically adjusts resource allocation based on real-time network conditions and device needs. The distributed ledger continuously records and updates resource transactions, enabling flexible and adaptive resource sharing that responds to changing load requirements, thereby improving both utilization and reliability simultaneously.

Inventive Principle:

Principle #15Dynamics

2Productivity

If cooperative communication techniques are implemented to increase resource utilization, then network performance is improved, but device complexity deteriorates

Engineering Contradiction:

Improveresource utilizationVSAvoidcoordination mechanism complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The distributed transaction ledger serves as an intermediary mechanism that simplifies cooperative communication. Instead of direct complex coordination between devices, the ledger acts as a neutral mediator that automatically records, tracks, and verifies resource transactions, reducing the coordination burden on individual devices while enabling efficient resource sharing.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Each wireless device maintains a local copy of the distributed transaction ledger, eliminating the need for constant centralized verification. This copying mechanism allows devices to independently verify resource transactions using their local copies, reducing communication overhead and device complexity while maintaining accurate resource tracking.

Inventive Principle:

Principle #26Copying

3Loss of information

If distributed transaction ledger is used to track resource sharing, then resource management transparency is improved, but processing overhead deteriorates

Engineering Contradiction:

Improveresource tracking transparencyVSAvoidprocessing overhead

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

Devices perform partial verification of resource transactions using their local ledger copies rather than verifying every transaction centrally. This partial action approach maintains sufficient transparency for resource tracking while significantly reducing the processing overhead and energy consumption associated with complete verification of all transactions.

Inventive Principle:

Principle #16Partial or excessive action
