A Stochastic Optimization Framework for Joint RAN Intelligent Controller Placement and RAN Nodes Assignment in O-RAN Networks

, 2023
<p>O-RAN Architecture is consolidating the concept of software-defined cellular networks (SDCNs) for beyond 5G networks, mainly through the introduction of the Near-Real-Time RAN Intelligent Controller (Near-RT RIC) and the xApps. In this context, the deployment of the Near-RT RIC faces the traditional controller placement problem in an SDCN ...

Machine Learning-Based Early Attack Detection Using Open RAN Intelligent Controller

ICC 2023 - IEEE International Conference on Communications, 2023
We design and demonstrate a method for early detection of Denial-of-Service attacks. The proposed approach takes advantage of the OpenRAN framework to collect measurements from the air interface (for attack detection) and to dynamically control the operation of the Radio Access Network (RAN).

Data-Driven Orchestration for Distributed RAN Intelligent Controller Placement in 6G Networks

Proceedings of the 40th ACM/SIGAPP Symposium on Applied Computing
Open-Radio Access Network ( O-RAN ) brings an innovative approach to address the issues of controller placement in large-scale 6G networks. In this work, we introduce a Reinforcement Learning (RL ) algorithm for decentralized RAN Intelligent Controller Orchestration in 6G Networks, which leverages the online learning capabilities of a multi-agent RL ...
