Forewarned is Forearmed: A Responsive Congestion Control with Non-intrusive Uplink Dynamics Capture

The cellular uplink is increasingly important for modern applications but poses significant challenges to congestion control algorithms (CCAs), due to the highly dynamic conditions and complex operations. Existing CCA paradigms, mainly for downloading data, are unable to react promptly to uplink fluctuations because th...

Optimized energy-efficient scheduling for multi-path TCP using distributed constraint and Max-Sum algorithms

SEELE: Sense-Driven Edge-Cloud Foreground–Background Split Rendering for Immersive Media Services

This paper proposes SEELE, a Lyapunov-guided online control algorithm that represents accumulated budget pressure with two virtual queues and converts the long-term constrained problem into lightweight per-slot decisions, and provides steady-state QoE statistically comparable to a pretrained PPO policy while significan...

Non-Intrusive Handover Strategy Optimization for Model-Partitioned DNN Inference in Satellite Edge Computing

As Satellite Edge Computing (SEC) emerges as a computing backbone of 6 G IoT, its feasibility is threatened by frequent handovers that disrupt task continuity and cause deadline violations in AI-driven workloads. Conventional communication-centric handover strategies overlook the urgency of computational tasks, further...
