Dynamic Wakeup under Costly Collisions
Umesh Biswas, Maxwell Young
The wakeup problem captures a fundamental symmetry-breaking challenge among devices sharing a communication channel. We study the dynamic setting, where packets become active at ar…
Resource versus Responsiveness: Benchmarking SDN Controller Runtimes for a Moving-Target-Defense Control Plane at Scale
Souhail Chakkour, Umesh Biswas, Charan Gudla
Network Moving Target Defense (MTD) built on Software-Defined Networking (SDN) continuously rotates host-facing addresses to invalidate an attacker's reconnaissance. Each rotation…
Right Knowledge, Wrong Answer: Characterizing Parametric Temporal Conflict in Open-Weight Language Models
Elias Hossain, Sourav Saha, Tasfia Nuzhat Ornee +5
Language models may encode both outdated facts and their newer replacements. We introduce Parametric Temporal Conflict (PTC), where the newer fact is present and recoverable, but t…
Attribution-Driven Explainable Intrusion Detection with Encoder-Based Large Language Models
Umesh Biswas, Shafqat Hasan, Syed Mohammed Farhan +2
Software-Defined Networking (SDN) improves network flexibility but also increases the need for reliable and interpretable intrusion detection. Large Language Models (LLMs) have rec…
