Solution Overview

Problem

In wireless networks, existing methods lack an efficient mechanism for devices to discover and communicate with each other using compatible wireless networking protocols, hindering seamless peer-to-peer communication.

Innovation Solution

A broker station receives activation requests from client stations indicating supported protocols, compiles capabilities, and sends networking capability messages to identify compatible stations, facilitating peer-to-peer communication by selecting optimal protocols based on throughput, power consumption, and forwarding capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If devices communicate via a central station in wireless networks, then network management and protocol coordination are simplified, but communication efficiency and resource usage increase due to centralized routing

Engineering Contradiction:
Improvenetwork managementVSAvoidresource usage
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The patent introduces a broker station as an intermediary that maintains capability information about all devices in the network. When two devices need to communicate, the broker station mediates the connection by providing compatibility information, enabling direct peer-to-peer communication while the broker remains as a lightweight coordination intermediary. This resolves the contradiction by maintaining simplified management through the broker while enabling efficient direct communication paths that reduce resource usage compared to centralized routing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of energy

If devices use peer-to-peer communication directly, then communication efficiency and resource usage are improved, but device discovery and protocol compatibility become more complex

Engineering Contradiction:
Improveresource usageVSAvoiddevice discovery
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The broker station performs preliminary actions by maintaining up-to-date capability information about all devices in the network before communication is needed. When devices need to communicate, the broker station has already prepared the compatibility information, eliminating the need for complex real-time discovery protocols. This resolves the contradiction by shifting the complexity to a preliminary setup phase managed by the broker, while device-to-device communication remains simple and efficient.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple wireless networking protocols are supported by devices, then adaptability and compatibility are improved, but device complexity and protocol management increase

Engineering Contradiction:
Improveprotocol compatibilityVSAvoidprotocol management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the complexity of protocol compatibility management from individual devices and centralizes it in the broker station. Each device only needs to report its capabilities to the broker, which then maintains and queries this information to determine compatibility. This resolves the contradiction by allowing devices to support multiple protocols (maintaining adaptability) while the broker handles the complex task of matching compatible devices (reducing device complexity).

Inventive Principle:
Principle #2Taking out (Extraction)
