Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of wirelessly connected devices, especially IoT devices, necessitates automatic location determination within networks for security and configuration, while existing methods are burdensome and vulnerable to security threats like wardriving, where devices outside physical boundaries can access sensitive data.
Innovation Solution
Equipping devices with location detection sensors that use a combination of light direction sensors, laser rangefinders, and wireless interfaces to automatically determine device locations relative to others, enabling a sensor management system to map sensors to a physical space and deploy security measures against unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual location determination and device registration is used, then security configuration can be achieved, but the process becomes burdensome and time-consuming
Solution Approach 1:
The system enables devices to automatically determine their own physical locations using onboard sensors (GPS, accelerometers, gyroscopes) and autonomously register with the network without human intervention. The sensor data is automatically processed to establish device locations and configure security policies based on those locations.
2Adaptability or versatility
If wireless networks are expanded for device connectivity, then device communication is enabled, but security vulnerabilities increase due to wardriving threats
Solution Approach 1:
The system proactively prevents wardriving attacks by using location detection to identify devices outside the physical perimeter before they can compromise the network. Security policies are pre-configured to automatically block or alert on devices detected outside authorized geographic boundaries, counteracting potential threats before they materialize.
Solution Approach 2:
The system continuously monitors device locations through sensor data and provides real-time feedback to the security management system. This feedback loop enables dynamic adjustment of security policies based on current device positions, allowing the system to respond to potential security threats as they develop.
3Productivity
If automatic location determination is implemented, then device registration is streamlined, but device complexity increases due to additional sensors
Solution Approach 1:
The system uses multi-functional sensor arrays that serve both location determination and security monitoring purposes. The same GPS, accelerometer, and gyroscope components used for geographic location detection also provide data for motion pattern analysis and wardriving threat detection, eliminating the need for separate dedicated sensors.

AI summary
Determining the physical location of wirelessly connected devices within a network can provide a number of security benefits. However, manually determining and configuring the physical location of each device within a system can be burdensome. To ease this burden, devices within a network are equipped with a location detection sensor that is capable of automatically determining a device's location in relation to other devices within the network. A location detection sensor (“sensor”) may include a light source, a light direction sensor, a rangefinder, and a radio or wireless network interface. Two location detection sensors can perform a location detection process to determine their relative locations to each other, such as the distance between them. As more sensors are added to a network, a sensor management system uses the relative locations determined by the sensors to map the sensors to a physical space layout.
