Cloud, Edge, or Split? Profiling Onboard and Split Vision-Language Model Deployment for Drone AI
Zoha Azimi, Reza Farahani, Schahram Dustdar +1
Vision-Language Models (VLMs) enable edge devices like unmanned aerial vehicles (UAVs) to interpret visual observations and reason about complex environments using natural-language…
DRLM: Deep Reinforcement Learning-Based LLM Query Orchestration in Edge Environments
Reza Farahani, Zoha Azimi Ourimi, Mario Colosi +3
Large language model (LLM) services increasingly process heterogeneous queries with diverse latency, accuracy, and resource requirements. While edge deployment reduces response tim…
LMEdge: QoS-Aware LLM Inference Orchestration on Edge Clusters
Reza Farahani, Zoha Azimi, Mario Colosi +1
Large language model (LLM) services increasingly operate on edge infrastructure, enabling low-latency and privacy-preserving AI services. However, efficiently serving LLM requests…
Scale: Deep Reinforcement Learning for Container Scheduling in Serverless Edge Computing
Chen Chen, Zihan Jia, Andrea Sabbioni +2
Serverless computing has emerged as a promising computing paradigm for edge computing. However, adopting the event driven model in highly dynamic, heterogeneous, and distributed ed…
Orchestrating Serverless Applications in the Edge Cloud Space Continuum: What Breaks and What is Next?
Hadi Tabatabaee Malazi, Reza Farahani, Nitinder Mohan +1
Serverless computing has matured into an effective execution model for edge cloud environments, enabling function level decomposition, demand driven scaling, and workflow execution…
ClusterLess: Deadline-Aware Serverless Workflow Orchestration on Federated Edge Clusters
Reza Farahani, Mario Colosi, Ilir Murturi +4
The recent convergence of edge computing, serverless execution, and Kubernetes (K8s) based container orchestration has enabled the processing of application workflows close to data…
DQ-Ladder: A Deep Reinforcement Learning-based Bitrate Ladder for Adaptive Video Streaming
Reza Farahani, Zoha Azimi, Vignesh V Menon +4
Adaptive streaming of segmented video over HTTP typically relies on a predefined set of bitrate-resolution pairs, known as a bitrate ladder. However, fixed ladders often overlook v…
Agentic Service Markets Across the Computing Continuum: A Polymatroidal Architecture
Lauri Lovén, Alaa Saleh, Reza Farahani +5
Autonomous AI agents are becoming economic actors. They compose deadline-bound services across the device-edge-cloud continuum and contend for capacity no single operator owns. Thi…
Osmotic Learning: A Self-Supervised Paradigm for Decentralized Contextual Data Representation
Mario Colosi, Reza Farahani, Maria Fazio +2
Data within a specific context gains deeper significance beyond its isolated interpretation. In distributed systems, interdependent data sources reveal hidden relationships and lat…
Serverless Everywhere: A Comparative Analysis of WebAssembly Workflows Across Browser, Edge, and Cloud
Mario Colosi, Reza Farahani, Lauri Loven +2
WebAssembly (Wasm) is a binary instruction format that enables portable, sandboxed, and near-native execution across heterogeneous platforms, making it well-suited for serverless w…
Toward Sustainability-Aware LLM Inference on Edge Clusters
Kolichala Rajashekar, Nafiseh Sharghivand, Radu Prodan +1
Large language models (LLMs) require substantial computational resources, leading to significant carbon emissions and operational costs. Although training is energy-intensive, the…
DEEP: Edge-based Dataflow Processing with Hybrid Docker Hub and Regional Registries
Narges Mehran, Zahra Najafabadi Samani, Reza Farahani +2
Reducing energy consumption is essential to lessen greenhouse gas emissions, conserve natural resources, and help mitigate the impacts of climate change. In this direction, edge co…
