Energy consumption data management center requires the gateway device to collect lots of energy data come from energy meters. However, these meters use different communication protocols other than TCP/IP protocol, so it can not be transmit these energy data across these energy data across TCP/IP networks. This problem is usually resolved by a data gateway in the energy management system. But the communication...
This paper investigates orthogonal frequency-division multiple-access (OFDMA) resource-allocation schemes for two-hop relays in a home powerline communication (PLC) network. Unlike wireless channels, which can have noticeable path loss and shadow effects to bring a substantial relay gain, the powerline channel usually observes a quality of the relay channel on par with the direct link so that simple...
