Mobility-aware service migration and two-timescale task offloading for distributed edge computing in open RAN

This paper proposes a mobility-aware two-timescale orchestration framework for distributed edge computing in Open Radio Access Networks, where user mobility, handover events, service migration, task offloading, and radio–compute allocation are jointly considered. The framework exploits the functional separation between...

A resource-aware framework for energy and bandwidth efficient IoT intrusion detection using lightweight federated learning over SDN

The rapid growth of Internet of Things (IoT) deployments has widened the network attack surface while increasing the cost of centralised intrusion detection, particularly when raw traffic must be moved to remote servers. We propose HFL-SDN-IDS, a hierarchical, resource-aware framework that combines a lightweight federa...
