CORMO-RAN: Energy Efficiency at the Near-RT RIC via Lossless Migration of O-RAN xApps
This paper proposes CORMO-RAN, a data-driven orchestrator that dynamically activates compute nodes based on xApp load to save energy, and performs lossless migration of xApps from nodes to be turned off to active ones while ensuring xApp availability during migration.
