P2P Network Topology Control for Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing peer-to-peer (P2P) networks face performance deterioration due to deep hierarchies and restricted node connections, limiting the maximum number of nodes that can form the network.
Innovation Solution
A portable electronic device transitions between states (root, branch, leaf, or non-associated) to control topology and connections dynamically, using a topology control section to manage acceptance or rejection of connections based on wireless status, thereby optimizing network configuration and maximizing node participation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If P2P network is configured according to receiving quality, then network performance is optimized, but hierarchy becomes extremely deep and communication performance deteriorates
Solution Approach 1:
The patent implements dynamic topology control where each portable electronic device transitions between states (root node, branch node, leaf node, non-associated node) based on real-time wireless connection status. This dynamic state transition allows the network to adapt its hierarchy depth dynamically, preventing excessively deep hierarchies while maintaining optimized network performance through flexible reconfiguration.
2Stability of the object's composition
If connection restriction is applied to prevent grandchild node connection, then network stability is improved, but maximum number of nodes cannot be maximized
Solution Approach 1:
The patent removes static connection restrictions and implements dynamic topology control where devices can transition between root, branch, and leaf node states based on real-time conditions. This allows the network to flexibly accommodate more nodes by dynamically adjusting the hierarchy structure, maximizing node capacity while maintaining stability through adaptive reconfiguration rather than rigid constraints.

AI summary
A portable electronic device includes a topology control section that controls a topology of a P2P network. The topology control section controls, when the portable electronic device functions as a root node, acceptance or rejection of connection of another portable electronic device that functions as an non-associated node to each node under control of the portable electronic device, and controls, when the portable electronic device functions as a branch node or a leaf node, acceptance or rejection of connection of the other portable electronic device that functions as the non-associated node to the portable electronic device according to the control of a root node.
