Solution Overview
Problem
Existing wireless communication systems face challenges in quickly and easily connecting multiple wireless devices in a WLAN system, requiring significant user intervention and time, especially when extending the service area with a multi-hop network topology.
Innovation Solution
A method and apparatus that utilize a center node to sense target nodes requesting connection within a predetermined time, allowing sequential configuration of connections through discovered nodes within a transmission area, minimizing user operation and time required for connection, and optimizing network performance by considering the number of connected nodes and hops from the center node.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional connection methods are used in WLAN systems, then connection reliability is maintained, but connection time increases and user operation becomes complex
Solution Approach 1:
The patent implements automatic connection configuration where the system itself performs the connection setup without requiring user intervention. The center node automatically senses target nodes, discovers available connections, and configures multi-hop paths, enabling the network to self-organize and eliminate manual configuration steps.
Solution Approach 2:
The patent performs preliminary sensing and discovery actions before actual connection is needed. The center node continuously senses target nodes within transmission areas and pre-discovers available communication paths, so when connection is required, the configuration can be rapidly established using pre-gathered information.
2Extent of automation
If automatic connection configuration is implemented, then user operation is minimized, but system complexity increases
Solution Approach 1:
The patent segments the connection configuration function into distinct roles: center nodes perform sensing and sequential configuration, normal nodes perform discovery and connection attempts, and target nodes request connections. This segmentation distributes complexity across multiple nodes with specialized functions rather than requiring all nodes to handle all configuration tasks.
Solution Approach 2:
The patent introduces center nodes as intermediary entities that mediate between target nodes seeking connection and the existing network group. Center nodes sense target nodes, manage the sequential configuration process, and coordinate normal nodes for discovery and connection, thereby simplifying the overall system architecture by centralizing control functions.
3Area of stationary object
If multi-hop network topology is used to extend service area, then network coverage increases, but connection configuration time increases
Solution Approach 1:
The patent performs preliminary discovery and path identification actions before connection is needed. Normal nodes continuously discover other nodes within transmission areas and report back to center nodes, which build knowledge of available multi-hop paths in advance, enabling rapid connection configuration when service area extension is utilized.
Solution Approach 2:
The patent enables the network to automatically configure multi-hop connections without user intervention. When a target node needs to connect through extended service area, the center node automatically senses the requirement, identifies appropriate normal nodes for relay, and sequentially configures the multi-hop path using pre-disccovered node information.
4Reliability
If sequential configuration of multiple target nodes is performed, then connection reliability is improved, but total configuration time increases
Solution Approach 1:
The patent maintains continuous useful action during sequential configuration by having the center node sense and process multiple target nodes concurrently where possible, and having normal nodes continuously discover and report node information. While configuration proceeds sequentially for reliability, the sensing, discovery, and preparation actions continue without interruption, reducing idle time between configuration steps.
