Solution Overview
Problem
Existing wireless network technologies cannot automatically establish a stable linear topology that adapts to dynamic changes in a complex environment, such as railway applications, as they rely on manual configuration which is impractical for dynamic and changing topologies.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration of network identities is used to establish a linear topology, then the network topology can be established in simple environments, but it cannot adapt to dynamic and complicated environments such as railway applications
Solution Approach 1:
The wireless devices automatically select connection targets based on signal quality metrics without requiring manual configuration. Each device autonomously detects signal quality from neighboring devices, evaluates candidates, and establishes connections dynamically, enabling the network to adapt to changing environments like railway applications where topology changes frequently
Solution Approach 2:
The system implements dynamic topology formation by continuously monitoring signal quality and allowing devices to reselect connection targets when conditions change. This dynamic adaptation enables the network to respond to environmental changes, device movements, and varying signal conditions in real-time, making it suitable for complex dynamic environments
2Adaptability or versatility
If automatic selection based on signal quality is implemented, then the network can adapt to dynamic environments, but the device complexity increases due to signal quality detection and evaluation mechanisms
Solution Approach 1:
The signal quality detection mechanism serves multiple functions: it identifies connection targets, evaluates candidate suitability, and provides input for automatic connection management. By making the detection system multi-functional, the patent reduces the need for separate dedicated components for each function, thereby limiting the increase in device complexity while achieving automatic topology adaptation
3Stability of the object's composition
If devices select connection targets without considering signal quality duration, then the connection process is faster, but the network stability decreases in dynamic environments
Solution Approach 1:
The system performs preliminary evaluation of signal quality duration before finalizing connection selections. By assessing whether signal quality has been maintained for a sufficient threshold period, devices can pre-validate connection candidates, ensuring stable connections are formed while avoiding rapid fluctuations. This preliminary check balances stability requirements with reasonable connection establishment time

AI summary
A wireless device for selecting a connection target based on signal quality, a system and a method thereof are provided. The invention selects a candidate device having the best signal quality and duration of the signal quality is not less than a threshold reaching a certain time. If the selected candidate device also selects the wireless device, a unique connection is established between the wireless device and the candidate device. In a dynamical and complicated environment, the disclosed system and the method can build up a stable linear topology through automatic negotiation among wireless devices. The invention then achieves the effect of updating topology in time to adapt to environment changes.
