Wireless Network Emission Regulation via Intermediary Signal Echoing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing congestion window system and tournament method in wireless local area networks (WLANs) suffer from significant collisions due to the phenomenon of hidden stations, leading to bandwidth loss and disturbed receptions, especially in multimedia applications requiring high transmission rates.
Innovation Solution
A transmission regulation method that involves stations sending signals to indicate authorization to transmit, allowing other stations to echo these signals and thereby inform each other of transmission authorizations, thereby avoiding collisions between stations that would otherwise transmit simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the tournament method is used to regulate packet transmissions, then collision rate is reduced and bandwidth efficiency is improved, but the effectiveness is reduced in the presence of hidden stations causing collisions
Solution Approach 1:
The patent introduces an intermediary signal mechanism where stations transmit acknowledgment signals to inform other stations about their transmission authorization status. This intermediary communication layer allows stations to detect when another station is authorized to transmit, even when hidden station conditions prevent direct detection of the authorization signal, thereby reducing collisions while maintaining bandwidth efficiency.
2Speed
If stations transmit without knowing if another station is authorized, then transmission speed is maintained, but collisions occur causing bandwidth loss
Solution Approach 1:
The patent implements a feedback mechanism where stations transmit acknowledgment signals after being authorized to send packets. This feedback loop allows other stations to detect the authorization status and adjust their transmission behavior accordingly, preventing collisions and avoiding bandwidth loss while maintaining high transmission rates for authorized stations.

AI summary
Method of regulating sending implemented by a station (B) during a tournament for access to a wireless communication network, the method comprising in the course of a round of said tournament: a step of reception (Q40) of a first signal, sent by another station and indicating that this other station (A, C) has obtained during said round of said tournament an authorization to send a data packet, a step of sending (G60) of a second signal indicating that said station has received the first signal.
