AI or Real: Detecting Partially Altered Videos Under Resource-Constrained Environments
Tamoghna Chakraborty, Md Nurul Absur, Sourya Saha +1
The proliferation of generative video models has shifted the practical detection threat from fully fabricated clips to partially manipulated footages. Although modern detectors ach…
Round Trip Time: A Benign Signal or an Indirect Window into Datacenter Workloads?
Sourya Saha, Md Nurul Absur, Saptarshi Debroy
Multi-tenant datacenter networks increasingly rely on shared leaf-spine fabrics, where traffic from multiple tenants traverses common network resources. While logical isolation mec…
ProFlow: RL-Driven and Performance-Aware Proactive Flow Placement in Datacenter Networks
Sourya Saha, Md Nurul Absur, Saptarshi Debroy
In datacenter fabrics composed of leaf and aggregation switches, competing flows may become co-located on shared aggregation switches, creating congestion that can significantly de…
Understanding Sensor Vulnerabilities in Industrial XR Tracking
Sourya Saha, Md. Nurul Absur
Extended Reality (XR) systems deployed in industrial and operational settings rely on Visual--Inertial Odometry (VIO) for continuous six-degree-of-freedom pose tracking, yet these…
Reinforcement Learning-Driven Edge Management for Reliable Multi-view 3D Reconstruction
Motahare Mounesan, Sourya Saha, Houchao Gan +2
Real-time multi-view 3D reconstruction is a mission-critical application for key edge-native use cases, such as fire rescue, where timely and accurate 3D scene modeling enables sit…
Detection of Misreporting Attacks on Software-Defined Immersive Environments
Sourya Saha, Md Nurul Absur, Shima Yousefi +1
The ability to centrally control network infrastructure using a programmable middleware has made Software-Defined Networking (SDN) ideal for emerging applications, such as immersiv…
Detection and Recovery of Adversarial Slow-Pose Drift in Offloaded Visual-Inertial Odometry
Soruya Saha, Md Nurul Absur, Saptarshi Debroy
Visual-Inertial Odometry (VIO) supports immersive Virtual Reality (VR) by fusing camera and Inertial Measurement Unit (IMU) data for real-time pose. However, current trend of offlo…
Reliable Multi-view 3D Reconstruction for `Just-in-time' Edge Environments
Md. Nurul Absur, Abhinav Kumar, Swastik Brahma +1
Multi-view 3D reconstruction applications are revolutionizing critical use cases that require rapid situational-awareness, such as emergency response, tactical scenarios, and publi…
Poster: Reliable 3D Reconstruction for Ad-hoc Edge Implementations
Md Nurul Absur, Swastik Brahma, Saptarshi Debroy
Ad-hoc edge deployments to support real-time complex video processing applications such as, multi-view 3D reconstruction often suffer from spatio-temporal system disruptions that g…
