This paper investigates xApp conflict management in O-RAN from an admission-control perspective. We consider a representative conflict between a conditional handover (CHO) xApp and an energy-saving xApp, where inconsistent control actions may target the same small cell. To protect service-critical CHO actions, we propo...
The increasing deployment of internet of things (IoT) low-power networks (LPNs) introduce a fundamental challenge in achieving low-latency communication while maintaining strict energy constraints under dynamic and heterogeneous traffic conditions. Existing medium access control (MAC) protocols either rely on rigid tim...
: Mobile edge services require deterministic communication across Time-Sensitive Networking (TSN) and 5G access, where the standardized integration architecture exposes the 5G System (5GS) to the TSN controller as a logical bridge. We study dynamic admission of time-triggered (TT) flows using reported 5GS bridge delay...
Time-sensitive networking (TSN) aims to provide bounded latency and reliable delivery for critical applications. Existing cyclic queuing and forwarding (CQF)-based mechanisms commonly rely on centralized flow-level scheduling, path computation, and resource reservation, requiring prior knowledge of traffic demands and...
A Priority-Aware Packet Aggregation/Piggybacking-Based (Priority + Packet Aggregation) Hybrid Energy-Efficient MAC (P2A-HMAC) protocol that integrates bit-mapped priority signaling with lightweight packet aggregation/piggybacking to reduce control overhead is proposed.
The lack of determinism restricts the integration of safety-critical applications into Edge–Fog–Cloud (EFC) architectures. Existing EFC schedulers are typically designed for dynamic, best-effort operation based on unmanaged resource allocation and elastic virtualization. This paradigm introduces unbounded queueing, res...
