Methods and systems to detect and counter denial of service attack in vehicle communications

A method for detecting and countering denial of service attacks in V2X communication, comprising:

• providing a vehicle with a wireless communication system including an antenna;
• providing a controller in communication with the wireless communication system;
• establishing, by the antenna and the wireless communication system, a communication range area surrounding the vehicle;
• receiving, by the wireless communication system, a wireless communication;
• analyzing, by the controller, the wireless communication and determining, by the controller if a first condition is satisfied;
• in response to determining that the first condition is satisfied, calculating, by the controller, an angle of arrival of the wireless communication;
• predicting, by the controller, a location of a source of the wireless communication relative to the vehicle;
• and
• adjusting, by the controller, a gain pattern of the antenna to block reception of additional wireless communications from a first area of the communication range area that includes the source of the wireless communication.

A system for detecting and countering denial of service attacks in V2X communication, comprising:

• a vehicle having a wireless communication system including an antenna and a controller in communication with the wireless communication system, the controller configured to receive a signal from the wireless communication system;
• analyze the signal and determine if a first condition is satisfied;
• in response to determining that the first condition is satisfied, calculate an angle of arrival of the signal;
• predict a location of a source of the signal relative to the vehicle;
• and
• adjust a gain pattern of the antenna to block reception of additional signals from the source of the signal.
