6Lo-based LWM2M Smart Metering System for IoT

The purpose of smart grid is to construct new energy efficient services that measure and control residential electricity consumption in the real time. Nowadays, 6LoWPAN has emerged as a key network technology for Neighbor Area Network(NAN) and Home Area Network(HAN) in smart grid because it enables constrained smart meters to be globally connected to each other with low-power consumption. However, since those constrained smart meters operate on the low-data rate IEEE 802.15.4 mac protocol, the system for lightly measuring and controlling them should be required in smart grid. In this paper, we introduce a novel smart metering system for smart grid, which provides lightweight smart meter management mechanism using OMA lightweight M2M(LWM2M) standard and lightweight IPv6 communication using SNAIL: 6LoWPAN platform. In addition, by constructing web service for our system, anyone can easily analyze the electricity consumption for home appliances and control them with interoperability.
