Group Owner Negotiation in P2P Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized wireless communication protocols in WLANs face challenges in managing network services, particularly in enterprise networks, as they require additional APs and reconfiguration to handle increased data traffic, leading to latency and high capital costs, while decentralized P2P protocols lack effective management mechanisms.
Innovation Solution
A managed P2P wireless network where access points operate as Group Owners, advertising P2P services and managing group formation through phases like Device Discovery, Group Owner Negotiation, and Group Management, using broadcast and unicast messages to facilitate direct communication among P2P devices without central AP routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized wireless communication protocol is used, then network service management is well-defined, but additional APs and reconfiguration are needed for increased traffic, leading to high capital costs and latency
Solution Approach 1:
The patent segments the network into P2P groups where devices communicate directly without requiring centralized AP routing. This divides the network traffic into independent P2P communication channels, eliminating the bottleneck of centralized AP management and reducing the need for additional APs to handle increased traffic.
Solution Approach 2:
The patent introduces a new dimension of direct P2P communication alongside the traditional centralized AP architecture. By enabling devices to communicate directly in a peer-to-peer manner, it adds a parallel communication path that bypasses the AP routing requirement, thereby reducing latency and capital costs.
2Loss of time
If P2P communication protocol is used, then AP-controlled traffic is eliminated, but network service management becomes difficult
Solution Approach 1:
The patent introduces a service management component that acts as an intermediary between P2P communicating devices and network services. This mediator enables P2P devices to discover and access network services without requiring centralized AP control, thereby maintaining ease of operation while eliminating AP-controlled traffic routing latency.
Solution Approach 2:
The patent implements feedback mechanisms where P2P devices provide information about their communication status and service requirements. This feedback enables automatic service management and configuration, making P2P network management as easy as centralized management while maintaining the latency benefits of direct communication.
3Device complexity
If decentralized P2P architecture is used, then capital costs are reduced, but effective management mechanism is lacking
Solution Approach 1:
The patent enables P2P devices to self-configure and self-manage their connections without requiring additional APs or complex centralized management. Devices automatically negotiate P2P group formation, service discovery, and communication parameters, thereby reducing capital costs while maintaining ease of operation through automated self-service mechanisms.

AI summary
According to one embodiment, a non-transitory computer readable medium within a first network device operating as an access point and comprising instructions which, when executed by one or more hardware processors, causes performance of a number of operations including transmission and reception of Peer-to-Peer messages between two or more network devices having Peer-to-Peer functionality. Thereafter, negotiations are conducted by network devices to selection of a Group Owner (GO) for a Peer-To-Peer group. The negotiations comprise specifically selecting a set of one or more values that ensures the first network device obtaining the GO role for Peer-to-Peer communications within the Peer-to-Peer group instead of randomly selecting the one or more values for the negotiating of the GO role.
