Securing 5G OpenRAN with a Scalable Authorization Framework for xApps

IEEE INFOCOM 2023 - IEEE Conference on Computer Communications, 2023
The ongoing transformation of mobile networks from proprietary physical network boxes to virtualized functions and deployment models has led to more scalable and flexible network architectures capable of adapting to specific use cases. As an enabler of this movement, the OpenRAN initiative promotes standardization allowing for a vendor-neutral radio ...

A unified service‐based capability exposure framework for closed‐loop network automation

Transactions on Emerging Telecommunications Technologies, Volume 33, Issue 11, November 2022., 2022
In this article, we motivate the need for an enhanced network exposure functionality for network automation. We motivate it by revising the state of the art, propose a candidate architecture, and proof its feasibility with a real world testbed.

Edge Intelligence‐Based RAN Architecture for 6G Internet of Things

Discrete Dynamics in Nature and Society, Volume 2022, Issue 1, 2022., 2022
Edge Intelligence, which blends Artificial Intelligence (AI) with Radio Access Network (RAN) and edge computing, is recommended as a crucial enabling technology for 6G to accommodate intelligent and efficient applications. In this study, we proposed Edge Intelligent Radio Access Network Architecture (EIRA) by introducing new intelligence modules, which

Optimal Control for Bufferbloat Queue Management Using Indirect Method with Parametric Optimization

Scientific Programming, Volume 2016, Issue 1, 2016., 2016
Because memory buffers become larger and cheaper, they have been put into network devices to reduce the number of loss packets and improve network performance. However, the consequences of large buffers are long queues at network bottlenecks and throughput saturation, which has been recently noticed in research community as bufferbloat phenomenon.
