This document presents a novel cost-efficient residential energy management (REM) scheme for home networks within smart grids, leveraging information-centric networking (ICN) to enhance data security, mobility, and content distribution. The proposed ICN-based home network (ICN-homenet) addresses existing challenges in traditional IP-based networks, while the ICN-REM scheme encourages consumers to shift appliance usage to off-peak hours to lower energy costs. Performance evaluations validate the effectiveness and correctness of this innovative approach, marking a significant advancement in residential energy management technology.
