Framework for Task Offloading in O‐RAN Architecture for Heterogeneous Computing Applications

Transactions on Emerging Telecommunications Technologies, Volume 37, Issue 2, February 2026.
This work proposes a task offloading framework in ORAN architecture, optimizing computational assignment across user devices, edge cloud, and regional cloud. By efficiently selecting processing nodes and allocating computational and radio resources, it minimizes delay while accommodating diverse latency requirements for gold, silver, and bronze‐tier ...

Securing xApps in Open RAN: A Hierarchical Approach to Authentication and Authorisation

2025 IEEE Conference on Communications and Network Security (CNS)
The Open Radio Access Network (RAN) represents a significant advancement in the ongoing evolution of mobile networks, transitioning from proprietary physical hardware to virtualised network functions. Open RAN advocates for a disaggregated RAN utilising commercial off-the-shelf (COTS) hardware.

Mobility Management for the Low‐Altitude Economy: Latency‐Aware Handover Design

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper develops a latency‐aware mobility‐management framework for aerial vehicles operating in hybrid terrestrial non‐terrestrial networks. We formulate a MILP for optimal AV AP association and propose a greedy handover policy using predicted coverage, rate and handover latency.

Inter-xApp Policy Conflicts in the O-RAN Near-RT RIC: Threat Modeling, Attack Characterization, and Lightweight Conflict-Aware Mitigation

IEEE Access
With the advent of the disaggregated, multi-vendor design of the Open Radio Access Network (O-RAN), third-party applications (xApps) can drive closed-loop control through the near-real-time RAN Intelligent Controller (near-RT RIC).
