| Abstract(in English) | In recent years, smart metering systems that efficiently control household resources such as water, electricity, and gas have attracted to increase the demand for reducing infrastructure operating costs. Each smart meter transmits the measured data to the Fusion Center (FC) via wireless multi-hop communication in a smart metering system. This means that new Smart Meters must be installed within the range where a wireless connection can be guaranteed to surrounding Smart Meters. Hence, installing a new smart meter is essential to obtain the radio propagation characteristics around the installation location. On the other hand, smart meters are installed in the corner of a house, and their height is lower than the height of the surrounding buildings. Therefore, it is challenging to adopt the empirical propagation model because the buildings around the terminal affect the communication between terminals. Given the above background, this paper aims to develop a highly accurate radio propagation prediction for smart meter systems installed in residential areas. We propose a combined NN (Neural network) to achieve this goal. The proposed NN consists of an NN that learns from parameters such as the positions at smart meters, a CNN that extracts features from satellite images around the terminals, and an NN that learns from the NN’s output in the previous stage. The proposed method reduces the standard deviation of the estimation error distribution by 3.02[dB] compared to the empirical model reported in ITU-R P.1411. |
