Cooperative Threat Detection for V2X Safety Message Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in V2X and D2D technologies, face challenges in detecting and mitigating threats that interfere with the transmission of basic safety messages (BSMs), such as jamming or misbehaving entities, which can obstruct wireless spectrum resources used in cooperative and automated driving decisions, leading to potential safety hazards.
Innovation Solution
A method where a first wireless device detects threat entities interfering with BSM transmission and shares information about these threats with other devices beyond the threat zone, allowing them to virtually sense the threat and determine alternative resources for BSM transmission, thereby mitigating contact and ensuring continued safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless devices transmit BSMs using available spectrum resources, then communication efficiency is improved, but vulnerability to jamming and interference from threat entities increases
Solution Approach 1:
The system performs preliminary detection of threat entities (jamming sources, misbehaving devices) before BSM transmission. Devices share threat information proactively, allowing receiving devices to pre-determine alternative resources or mitigation strategies, thus preventing interference before it affects safety message transmission.
Solution Approach 2:
The patent introduces an intermediary threat detection and sharing mechanism where devices communicate threat entity information to third-party devices. This intermediary information sharing allows devices to indirectly sense threats beyond their own detection range and make informed decisions about resource selection, resolving the contradiction between using available spectrum and avoiding interference.
2Reliability
If devices share threat information with other wireless devices, then system-wide safety is improved, but communication overhead and message transmission load increase
Solution Approach 1:
The patent extracts only the essential threat-related information (threat entity presence, type, location) from the full sensor data set for sharing. This selective extraction reduces the information overhead significantly while maintaining the ability to make safety-critical decisions, balancing system-wide safety with communication efficiency.
3Measurement precision
If devices use sensor sharing to detect threat entities beyond their own sensing range, then detection capability is improved, but device complexity and processing requirements increase
Solution Approach 1:
Instead of requiring each device to physically sense threats, the system creates information copies of threat detections from one device and shares them with others. This virtual sensing through information copying extends detection capability without requiring additional physical sensors or complex processing at each device, resolving the contradiction between detection precision and device complexity.
Data Source
AI summary
Method and apparatus for cooperative early threat detection. In some aspects, the apparatus detects one or more object data signals having data that interferes with wireless resources utilized in automated driving decisions. The apparatus transmits, to at least a second wireless device, a message indicating the one or more object data signals having the data that interferes with wireless resources utilized in automated driving decisions. The one or more object data signals may correspond to a misbehaving wireless device. The data of the misbehaving wireless device may comprise implausible data related to at least one characteristic of the misbehaving wireless device.
