Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing peer-to-peer networks face inefficiencies in message routing and failure recovery due to suboptimal node interconnectivity, leading to potential bottlenecks and reduced system performance.
Innovation Solution

Engineering Contradiction Analysis
1Device complexity
If nodes establish links with only X neighboring nodes in a circular ordering, then the device complexity is reduced, but the reliability and routing efficiency deteriorate due to insufficient redundancy
Solution Approach 1:
The patent segments the link establishment process into two distinct phases: first establishing deterministic links to X neighboring nodes (Di+1, Di+2, ..., Di+X) for efficient routing, then adding probabilistic redundant links for failure recovery. This segmentation allows the system to optimize for both low complexity and high reliability by treating these as separate functional requirements.
Solution Approach 2:
The patent performs preliminary action by pre-establishing the circular ordering of nodes and deterministic links before network operation begins. This preliminary structure ensures O(log N) routing efficiency from the start, while the subsequent addition of redundant links provides failure recovery without disrupting the primary routing paths.
2Reliability
If nodes establish additional redundant links beyond X neighbors, then the reliability improves through increased redundancy, but the device complexity and number of connections increases
Solution Approach 1:
The patent applies local quality by making the redundancy level node-specific rather than uniform. Each node Dj in the subset establishes additional redundant links, while other nodes maintain only the basic X neighboring links. This allows the system to concentrate redundancy where most beneficial while keeping overall complexity manageable.
Solution Approach 2:
The patent implements partial redundancy by having only a subset of nodes establish additional redundant links beyond their X neighboring connections, rather than requiring all nodes to do so. This partial action provides sufficient failure recovery capability while avoiding the excessive complexity that would result from universal redundancy.
3Adaptability or versatility
If the network uses a decentralized peer-to-peer structure, then the adaptability and versatility improve, but the difficulty of maintaining efficient routing and recovery increases
Solution Approach 1:
The patent changes the topological parameters of the decentralized network by imposing a circular ordering on nodes and defining specific link establishment rules based on node indices. This parameterization transforms the decentralized network into one with predictable structural properties, enabling O(log N) routing efficiency and systematic failure recovery without centralized control.
