Reinforcement Learning based Cyberattack Model for Adaptive Traffic Signal Controller in Connected Transportation Systems

no code implementations31 Oct 2022 Muhammad Sami Irfan, Mizanur Rahman, Travis Atkison, Sagar Dasgupta, Alexander Hainen

Specifically, an RL agent is trained to learn an optimal rate of sybil vehicle injection to create congestion for an approach(s).

Improving the Environmental Perception of Autonomous Vehicles using Deep Learning-based Audio Classification

no code implementations9 Sep 2022 Finley Walden, Sagar Dasgupta, Mizanur Rahman, Mhafuzul Islam

Although visual sensors of an AV, such as camera, lidar, and radar, help to see its surrounding environment, an AV cannot see beyond those sensors line of sight.

A Sensor Fusion-based GNSS Spoofing Attack Detection Framework for Autonomous Vehicles

no code implementations19 Aug 2021 Sagar Dasgupta, Mizanur Rahman, Mhafuzul Islam, Mashrur Chowdhury

Data from multiple low-cost in-vehicle sensors (i. e., accelerometer, steering angle sensor, speed sensor, and GNSS) are fused and fed into a recurrent neural network model, which is a long short-term memory (LSTM) network for predicting the location shift, i. e., the distance that an AV travels between two consecutive timestamps.

An Innovative Attack Modelling and Attack Detection Approach for a Waiting Time-based Adaptive Traffic Signal Controller

no code implementations19 Aug 2021 Sagar Dasgupta, Courtland Hollis, Mizanur Rahman, Travis Atkison

Thus, the objectives of this paper are to: (i) develop a "slow poisoning" attack generation strategy for an ATSC, and (ii) develop a prediction-based "slow poisoning" attack detection strategy using a recurrent neural network -- i. e., long short-term memory model.

Sensor Fusion-based GNSS Spoofing Attack Detection Framework for Autonomous Vehicles

no code implementations5 Jun 2021 Sagar Dasgupta, Mizanur Rahman, Mhafuzul Islam, Mashrur Chowdhury

In this study, a sensor fusion based GNSS spoofing attack detection framework is presented that consists of three concurrent strategies for an autonomous vehicle (AV): (i) prediction of location shift, (ii) detection of turns (left or right), and (iii) recognition of motion state (including standstill state).

Prediction-Based GNSS Spoofing Attack Detection for Autonomous Vehicles

no code implementations16 Oct 2020 Sagar Dasgupta, Mizanur Rahman, Mhafuzul Islam, Mashrur Chowdhury

A spoofed attack is difficult to detect as a spoofer (attacker who performs spoofing attack) can mimic the GNSS signal and transmit inaccurate location coordinates to an AV.
