The method involves using stationary replicator units to reflect location signals, allowing for position determination based on distances from both replicator units and anchor nodes, enhancing precision and resistance to attacks by increasing the number of available reference points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of stationary participants with line-of-sight connection is increased to improve localization precision, then measurement precision improves, but device complexity and installation costs increase
Solution Approach 1:
The patent introduces stationary replicator units as intermediary elements that reflect location signals between stationary participants and mobile participants. These replicator units create additional signal paths without requiring direct installation of new stationary participants, thereby improving localization precision while avoiding the complexity and cost of deploying more stationary participants.
Solution Approach 2:
The stationary replicator units create virtual copies of stationary participants by reflecting their signals. This allows the system to effectively increase the number of available reference points for localization without physically installing additional stationary participants, resolving the contradiction between measurement precision and device complexity.
2Measurement precision
If stationary replicator units are deployed to improve localization precision and reduce anchor node requirements, then measurement precision improves, but device complexity increases
Solution Approach 1:
The stationary replicator units are designed to autonomously reflect location signals without requiring complex control systems or additional infrastructure. Each replicator unit independently performs signal reflection, simplifying the overall system architecture while still improving localization precision and reducing the need for numerous anchor nodes.
3Reliability
If more stationary participants are installed to resist position simulation attacks, then reliability improves, but installation costs and device complexity increase
Solution Approach 1:
The stationary replicator units serve as intermediary elements that create additional verification paths for position determination. By reflecting signals from multiple stationary participants, they enable the system to detect and resist position simulation attacks without requiring a proportional increase in stationary participant density, thereby improving reliability while controlling installation costs.
