Peer-to-Peer Node Mode Transition Mechanism for DHT Stability

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

P2P networks face disruptions and resource inefficiencies due to the transition of devices from peer to client mode and vice versa, leading to load balance, routing, and data storage issues, as these transitions impact the distributed hash table (DHT) and increase resource consumption.

Innovation Solution

Implementing a mechanism that allows peer devices to transition between peer and client modes based on resource availability, such as battery power or bandwidth, while waiting for the DHT to exit a transition state before making changes, thereby minimizing the impact on the DHT and optimizing resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a peer device transitions between peer and client modes based on resource availability, then resource usage is optimized, but the disruption to the distributed hash table increases

Engineering Contradiction:

Improveresource usageVSAvoiddisruption to distributed hash table

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The system checks whether the DHT is in a transition state before allowing a peer device to change its mode. This preliminary check prevents mode transitions during critical DHT update periods, thereby reducing disruption to the DHT while still allowing resource optimization during stable periods.

Inventive Principle:

Principle #10Preliminary action

2Loss of energy

If a peer device transitions between peer and client modes, then resource consumption is reduced, but load balance and routing efficiency deteriorate

Engineering Contradiction:

Improveresource consumptionVSAvoidload balance and routing efficiency

Core Design Contradiction:

Loss of energyVSProductivity

Solution Approach 1:

The peer device dynamically adjusts its mode (peer or client) based on its current resource availability. When resources are sufficient, it operates as a peer to maintain load balance and routing efficiency. When resources are constrained, it transitions to client mode to reduce resource consumption, with the transition timed to minimize DHT disruption.

Inventive Principle:

Principle #15Dynamics

3Loss of time

If mode transitions are allowed during DHT transition states, then response time is reduced, but system stability deteriorates

Engineering Contradiction:

Improveresponse timeVSAvoidsystem stability

Core Design Contradiction:

Loss of timeVSStability of the object's composition

Solution Approach 1:

The system applies a counter-action by preventing mode transitions during DHT transition states. This preliminary restriction avoids compounding disruptions to the DHT, maintaining system stability even though it may slightly increase response time for mode changes.

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

An apparatus for providing data management in a P2P network may include a processor. The processor may be configured to identify resources and communicate information to another node(s). The information may include a request to change the apparatus from a first mode of operation to a second mode of operation based on the identified resources.
