Evasive Sensor Networks Using Dynamic Hiding Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor networks are vulnerable to detection, manipulation, and damage by unauthorized agents, as they rely on passive hiding methods that are not dynamic or responsive to real-time threats.
Innovation Solution
The implementation of active and dynamic hiding devices that automatically move cameras and associated structures in response to real-time sensor data, using a sensor monitoring system to direct hiding devices and structures to conceal or reveal cameras, enhancing survivability and durability by overlapping fields-of-view and employing various sensors to detect threats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive hiding methods are used for sensors, then the device complexity is reduced, but the reliability of sensor networks deteriorates due to vulnerability to detection and damage
Solution Approach 1:
The patent implements dynamic hiding mechanisms where cameras and sensors can actively move between exposed and hidden positions based on real-time threat detection. The system transitions from static passive hiding to dynamic active hiding, allowing sensors to respond adaptively to changing security conditions while maintaining network survivability
Solution Approach 2:
The sensor network performs self-protection through automated threat detection and response. When threats are detected, the system automatically activates hiding mechanisms without external intervention, allowing the network to protect itself dynamically based on real-time conditions
2Reliability
If active hiding mechanisms are implemented, then the reliability of sensors improves, but the device complexity increases due to additional moving parts and control systems
Solution Approach 1:
The patent employs multi-functional components that serve both sensing and hiding functions. The same camera system that monitors for threats also executes the hiding action, eliminating the need for separate dedicated hiding mechanisms and reducing overall system complexity while maintaining reliability
Solution Approach 2:
The system merges the threat detection function and the hiding execution function into an integrated unit. The camera that detects threats is the same camera that physically moves to hide, combining multiple functions into a single component to reduce complexity
3Productivity
If sensors remain exposed for monitoring, then the productivity of security monitoring is improved, but the sensors become vulnerable to detection, manipulation, and damage
Solution Approach 1:
The system implements periodic exposure and hiding cycles based on threat levels. Sensors alternate between exposed states for monitoring and hidden states for protection, creating a rhythmic pattern of operation that balances productivity with survivability through time-based segmentation of functions
4Reliability
If sensors hide frequently to avoid threats, then the survivability of the network improves, but the loss of time for evidence collection increases
Solution Approach 1:
The system implements rapid transition capabilities that allow sensors to quickly move between exposed and hidden states. This rushing through the hiding/revealing cycle minimizes the time sensors are hidden while still providing protection, reducing evidence collection loss by accelerating the response to threat conditions

AI summary
Networks of cameras and/or other sensors enable a sensor monitoring system or other computer system to control hiding devices used to enable the cameras and/or other sensors to evade danger by hiding or being disguised. Detection and/or determination of potential danger is garnered from data, from some of the cameras and/or sensors, that they or other of the cameras and/or sensors may be facing eminent danger of discovery, manipulation, alteration, deactivation, and/or damage. The hiding devices are caused to hide or disguise the sensors and/or cameras that appear to be in danger. Hiding or disguising can continue for at least a finite duration of time, or until indication of danger is gone. Some of the cameras and/or other sensors, and their associated hiding devices, can be turned off or made to sleep for periods of time until at least awaken by time-out events or by events indicating a need to do so.
