Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If transmission windows are configured for all neighbor network nodes, then node discovery completeness is improved, but signaling overhead and complexity increase
Solution Approach 1:
The patent applies local quality by configuring transmission windows selectively based on mobility conditions. Network nodes with high mobility receive different transmission window configurations compared to stationary nodes. This targeted approach ensures that node discovery is optimized for mobile nodes while avoiding unnecessary signaling overhead for stationary nodes, thus resolving the contradiction between discovery completeness and signaling complexity.
Solution Approach 2:
The patent implements dynamics by making transmission window configurations adaptive to mobility conditions. The network entity determines whether a node is mobile or stationary and dynamically adjusts the transmission window configuration accordingly. This dynamic approach allows the system to maintain high node discovery effectiveness for mobile nodes while reducing signaling overhead by not applying the same configuration to all nodes.
2Measurement precision
If transmission windows are configured for mobile network nodes, then node discovery effectiveness is improved, but interference from other nodes increases
Solution Approach 1:
The patent applies segmentation by dividing network nodes into different categories based on mobility conditions (mobile vs. stationary). Transmission windows are configured differently for each category. Mobile nodes receive transmission window configurations optimized for their mobility, while stationary nodes use different configurations. This segmentation reduces interference because transmission windows are tailored to specific node types, preventing stationary nodes from transmitting during windows intended for mobile node discovery.
Solution Approach 2:
The patent uses local quality by applying different transmission window configurations to different node categories. Mobile nodes receive one configuration while stationary nodes receive another. This localized configuration approach ensures that transmission windows are optimized for the specific mobility characteristics of each node type, thereby improving node discovery effectiveness for mobile nodes while minimizing interference from stationary nodes.
3Productivity
If transmission windows are configured for stationary network nodes, then resource utilization is improved, but node discovery for mobile nodes deteriorates
Solution Approach 1:
The patent implements dynamics by creating a dual configuration system where transmission windows are dynamically selected based on node mobility status. Stationary nodes use fixed transmission window configurations that optimize resource utilization, while mobile nodes receive adaptive configurations that accommodate their movement. This dynamic selection mechanism ensures that each node type operates with the most appropriate configuration, resolving the contradiction between resource utilization for stationary nodes and node discovery effectiveness for mobile nodes.
