P2P Group Ownership Delegation With Dynamic Device Ranking

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current implementations of peer-to-peer (P2P) networks struggle with the inability to delegate group ownership effectively, leading to network disbanding when the group owner leaves or a better-suited device joins, resulting in communication disruptions for out-of-range group clients.

Innovation Solution

A ranking list is maintained to facilitate the delegation of group ownership, incorporating intent and reachability values to select a new group owner, ensuring continuous network connectivity by updating the list periodically and establishing secure connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the group owner leaves the P2P network, then the network must be reorganized, but the network disbands and communication is disrupted

Engineering Contradiction:

Improvenetwork connectivityVSAvoidgroup ownership transition

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies preliminary action by maintaining a pre-sorted ranking list of candidate group owners before any departure occurs. When the current group owner leaves, the system can immediately promote the next suitable device from the pre-established ranking list without disruption, avoiding network disbanding and communication interruptions.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If a new station device joins with better capabilities, then network performance could improve, but the device cannot become group owner without network disbanding

Engineering Contradiction:

Improvedevice capability optimizationVSAvoidnetwork continuity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements dynamics by maintaining a living, updateable ranking list that reflects current device capabilities. When new devices join or capabilities change, the ranking list is dynamically updated, allowing the most capable device to become group owner through smooth transition rather than network disbanding, thus adapting to changing conditions while maintaining continuity.

Inventive Principle:

Principle #15Dynamics

3Reliability

If the group owner performs frequent sensing to monitor network conditions, then network management improves, but power consumption increases

Engineering Contradiction:

Improvenetwork management qualityVSAvoidgroup owner power overhead

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies self-service by having non-group-owner devices perform sensing and capability reporting autonomously. These devices self-report their status and capabilities to the group owner, eliminating the need for the group owner to continuously sense and query all devices, thus reducing the group owner's power overhead while maintaining effective network management.

Inventive Principle:

Principle #25Self-service

AI summary

Methods and systems for delegating group ownership in P2P networks. The disclosed method includes, among other things, responsive to a pending disconnection of the first station device from the P2P network, identifying, from a list of the plurality of station devices maintained by the first station device, a second station device to delegate ownership of the P2P network, and delegating ownership from the first station device to the second station device.
