Engineering Contradiction Analysis
1Reliability
If traditional wireless communication mechanisms are used for data packet transmission, then basic connectivity is maintained, but data loss occurs during path switching and resource utilization is suboptimal
Solution Approach 1:
The system performs preliminary actions by establishing multiple candidate data transmission paths before actual data transmission occurs. The network node selects an appropriate path based on current network conditions, ensuring that when path switching is needed, the alternative path is already prepared and can be activated immediately, thereby preventing data loss and optimizing resource utilization.
Solution Approach 2:
The mechanism incorporates feedback loops where acknowledgment packets are transmitted from the wireless device back to the network node. This feedback information about data receipt status and path performance is used to dynamically adjust future path selection and switching decisions, improving both reliability and resource utilization efficiency over time.
2Reliability
If multiple data transmission paths are implemented for lossless switching, then data transmission reliability improves, but network complexity increases
Solution Approach 1:
The system segments the data transmission path management into distinct functional components: path selection logic, path switching logic, and acknowledgment tracking logic. Each component handles a specific aspect of path management independently, making the overall complex system more manageable and easier to implement while maintaining high reliability through coordinated operation of these segmented functions.
