Engineering Contradiction Analysis
1Reliability
If current communication networks are used to support moving and static nodes, then basic connectivity is provided, but reliability and efficiency of data management deteriorate
Solution Approach 1:
The system segments the network into multiple access points (mobile and static) that can independently manage connections. Each access point operates as a separate entity that can be individually selected based on mobility requirements, thereby improving reliability without overwhelming the entire network with complexity.
Solution Approach 2:
The system dynamically adapts the network configuration based on the mobility of nodes. Mobile access points are activated when moving nodes are detected, while static access points handle stationary nodes. This dynamic adjustment improves connectivity reliability for moving nodes without permanently maintaining the complexity of having all access points active simultaneously.
2Area of stationary object
If a platform connects all mobile and static nodes, then connectivity coverage is improved, but power consumption increases
Solution Approach 1:
The system employs periodic detection of node mobility status and dynamically activates or deactivates access points based on current needs. Instead of continuously operating all access points, the system periodically assesses whether mobile or static access points are needed, thereby maintaining wide coverage while reducing power consumption during periods when certain access points are not required.
Solution Approach 2:
The platform automatically detects the mobility status of nodes and self-manages the activation of appropriate access points without requiring manual intervention. This self-service mechanism ensures comprehensive coverage is maintained while minimizing power consumption by only activating necessary access points based on real-time node characteristics.
3Reliability
If handover management is implemented for mobile nodes, then connectivity reliability is improved, but system complexity increases
Solution Approach 1:
The system introduces a platform as an intermediary that centrally manages handover decisions between mobile and static access points. This intermediary platform consolidates the complexity of handover management in a single entity, allowing individual access points to maintain simpler operation while still achieving reliable handovers through the coordinating platform's decision-making.
