Ad-Hoc Network Communication Device Denial Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ad-hoc wireless LAN networks, denying communication to specific devices without a central base station is complex and prone to errors, as existing methods require setting up denial settings for all devices, leading to potential unauthorized communication.
Innovation Solution
A communication device with a registering unit, notifying unit, and constructing unit that identifies and notifies other devices of denial targets, creating a separate network excluding the denial target device, thereby simplifying the process of denying communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If denial of connection is set in a base station for infrastructure network, then communication control is centralized and simple, but ad-hoc networks cannot utilize this mechanism and require complex configuration on all devices
Solution Approach 1:
The patent introduces a mediator device that receives denial requests from one device and distributes the denial information to all other devices in the ad-hoc network. This mediator acts as a temporary central authority, allowing one device to initiate denial without requiring manual configuration on all devices, thus resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The patent implements preliminary action by having devices pre-configure themselves to automatically receive and apply denial information from other network participants. When a device wants to deny connection to a specific device, the denial information is proactively distributed to all devices before any unauthorized communication can occur, eliminating the need for complex manual configuration
2Ease of operation
If simple communication parameter setting techniques like WPS are used, then communication setup is convenient and fast, but devices that should not communicate may easily connect
Solution Approach 1:
The patent applies preliminary anti-action by implementing a mechanism where devices can pre-register their denial targets before any communication attempt occurs. When a device wants to deny connection, it notifies all other devices in advance, creating a preemptive security layer that works seamlessly with simple parameter setting techniques like WPS, thus maintaining both ease of operation and reliability
3Reliability
If MAC address filtering is configured on all devices in ad-hoc network, then unauthorized devices can be blocked, but the operation becomes complicated and error-prone
Solution Approach 1:
The patent merges the denial configuration function across all devices by introducing a centralized notification mechanism. Instead of requiring independent configuration on each device, the system combines the configuration process into a single action initiated by one device, with automatic distribution to all others. This maintains the effectiveness of MAC address filtering while dramatically simplifying the operation

AI summary
[Object] To enable a device that is a target for denial of communication to be shared over a network.[Solution] A communication device registers identifying information of a denial target device that is present in a first network and that is a target for denial of communication and notifies another device of the registered identifying information of the denial target device. The communication device constructs a second network different from the first network with the other device.
