Wireless LAN Relay Path Priority Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless LAN systems require manual determination of relay devices for expanding communication range, leading to suboptimal relay paths with multiple devices of the same settings, and lack automated methods for setting efficient priority levels among relay devices.
Innovation Solution
A wireless LAN system comprising three or more devices with a program that determines connection to an outer network, sets priority levels for relay paths, and transmits these levels to other devices for efficient packet relaying, using a priority setting and storing section to establish an optimized relay path automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual determination of relay devices is used, then user control is maintained, but the relay path optimization and automation are compromised
Solution Approach 1:
The wireless relay devices automatically determine their own priority levels and establish relay paths without user intervention. Each device autonomously transmits priority information and selects relay destinations based on stored priority data, enabling self-configuration of the network topology.
Solution Approach 2:
The system introduces a priority level parameter that changes the behavior of relay device selection. Devices with higher priority levels are preferentially selected as relay destinations, and this parameter is dynamically transmitted and stored to optimize the relay path automatically.
2Productivity
If RSSI-based selection is used, then automatic connection is achieved, but optimal relay path with minimum relay points cannot be guaranteed
Solution Approach 1:
Priority levels are determined and stored in advance before actual data transmission occurs. Each wireless relay device pre-configures its priority information and stores it in memory, allowing for optimized relay path selection without requiring real-time calculations during data transmission.
Solution Approach 2:
The system implements a feedback mechanism where priority information is transmitted between devices and stored for future reference. This feedback loop allows devices to learn about each other's priority levels and make informed relay decisions, improving both path efficiency and connection stability.

AI summary
A wireless LAN device and a wireless LAN system including three or more wireless LAN devices are provided. A wireless LAN device includes a wireless communication section for performing wireless communication so as to relay a packet in a wireless network. The wireless communication section includes a priority transmitting section for transmitting a priority level of the wireless LAN device to one or more other wireless LAN devices; a priority receiving section for receiving a priority level of the one or more other wireless LAN devices from the one or more other wireless LAN devices, and storing the received priority level in a priority storing section; and a relaying section for relaying the packet to the one or more other wireless LAN devices that has the highest priority level among the priority levels stored in the priority storing section.
