Bitmap-Wise Wireless M-Bus Coordination for Sustainable Real Time Energy Management

Abstract

Even though WM-Bus is being considered to be the most promising network protocol for smart metering, it is not suitable for a sustainable real-time home energy management system (HEMS), which requires higher reliability and longer lifetime despite real time bi-directional communications. Therefore, in this paper we propose a Bitmap-wise WM-Bus (BWM-Bus), coping well with sustainable real-time HEMS. In particular, the proposed scheme addresses the several problems in WM-Bus for HEMS by introducing novel functions: asynchronous meter trigger, adaptive slot scheduling, and bitmapwise retransmission request. Through experiments, we demonstrate that BWM-Bus guarantees higher data success ratio with lower data aggregation time, as well as longer lifetime than WM-Bus standard.

Hierarchical multichannel-based integrated smart metering infrastructure

“…shows an example of Hi-MIMI retransmission. Hi-MIMI utilizes group ACK-based retransmission management introduced by Hwang and Nam [14], rather than individual ACK. After completion of OHD Report at this round, EDM first checks if there is lost data by checking the received bitmap, then retransmits OHD_Report_Request.…”

“…They use a bidirectional meter that spins in both directions [9]. When the customer exports energy to the utility, the meter spins in a clockwise direction [44,45]. If the user consumes power from the utility, the meter spins in the opposite direction [45].…”
