Communication Apparatus Mode Switching for Network Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IEEE802.11 wireless LAN systems, switching communication apparatuses from infrastructure mode to ad hoc mode is inconvenient for users, and there is no effective control over communication band allocation for Quality of Service (QoS) in direct link setups.
Innovation Solution
A communication system that allows communication apparatuses to adaptively form a new network independently of an existing network by switching between operation modes, enabling one apparatus to control others or operate under another's control, thereby forming a second network even when the existing communication band is insufficient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication apparatuses use infrastructure mode with an access point, then centralized control and network management are achieved, but communication efficiency and bandwidth availability are limited
Solution Approach 1:
The communication apparatus is designed to dynamically switch between infrastructure mode and ad hoc mode based on network conditions and requirements. This dynamic capability allows the system to optimize communication efficiency by selecting ad hoc mode when direct communication is beneficial, while maintaining the simplicity of infrastructure mode when centralized control is sufficient.
2Adaptability or versatility
If manual mode switching is implemented for each communication apparatus, then mode transition is possible, but user operation complexity and inconvenience increase
Solution Approach 1:
The communication apparatus automatically determines and switches between infrastructure mode and ad hoc mode based on pre-configured conditions and real-time network state, eliminating the need for manual user intervention. The system self-manages the mode transition process, making it convenient for users while maintaining adaptability to different communication scenarios.
3Productivity
If direct link setup is used for STA-to-STA communication, then communication efficiency improves, but QoS control and bandwidth management become insufficient
Solution Approach 1:
The system dynamically adjusts the communication mode between infrastructure and ad hoc based on QoS requirements and bandwidth availability. When high QoS control is needed, the system operates in infrastructure mode with AP-mediated control. When direct efficient communication is prioritized and QoS requirements are met, the system switches to ad hoc mode, thus balancing both communication efficiency and QoS control capability.

AI summary
In a communication system including a plurality of communication apparatuses, each communication apparatus has a first operation mode in which the communication apparatus controls communication of other communication apparatuses and a second operation mode in which the communication apparatus operates under the control of another communication apparatus. A network independent of an existing network is formed by switching the operation mode of one of communication apparatuses into the first operation mode.
