Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network devices use dynamic routing in wireless mesh networks, then network adaptability and connection reliability are improved, but route selection complexity and computational overhead increase
Solution Approach 1:
The patent implements feedback mechanisms where network devices continuously monitor RSSI values and route statuses, then adjust routing decisions based on this feedback. The first network device obtains RSSI values from multiple sources, calculates routing decision values, and selects connection targets dynamically based on current network conditions, creating a closed-loop control system that improves reliability while managing complexity through systematic decision-making
Solution Approach 2:
Each network device autonomously calculates its own routing decision values based on locally obtained RSSI information and connecting route weights. The first network device independently evaluates multiple potential connection targets and selects the optimal one without requiring centralized control, enabling self-service routing that reduces overall system complexity while maintaining high reliability
2Productivity
If network devices continuously monitor and reselect connection targets, then network efficiency is improved, but energy consumption and processing overhead increase
Solution Approach 1:
The patent implements dynamic routing where connection targets are not fixed but can change based on real-time network conditions. Network devices continuously monitor RSSI values and recalculate routing decision values when conditions change, allowing the system to adapt dynamically to improving or deteriorating signal conditions, thereby maintaining high network efficiency while energy is consumed only when reselection is beneficial
Solution Approach 2:
The system changes key parameters (RSSI values, connecting route weights, routing decision values) based on current network conditions rather than using fixed parameters. The first network device obtains updated RSSI values and recalculates routing decisions when network environment changes occur, allowing efficient operation during stable conditions while adapting when improvements can be made

AI summary
A wireless network system and a connection method for the wireless network are provided. A network device in the wireless network obtains the connecting route weights of a network base station and other network devices, the received signal strength indictor (RSSI) between the network device and the network base station, and the RSSIs between the network device and each of the other network devices. The network device obtains the routing decision values corresponding to the network base station and the other network devices and chooses the network base station or one of the other network devices corresponding to the highest routing decision value as the connection target. The network device can re-select its connection target according to environmental changes in the wireless network.
