In this paper, we propose an energy efficient machineto- machine (M2M) communication scheme for bidirectional automated metering (AMR) systems. In particular, to maximize the benefits of bidirectional AMR systems, we propose a scheme that enables near real-time M2M communication coupled with energy efficient operation. The energy efficient bidirectional M2M communication (EEBMC) basically divides each interval into three time sections: a regular report processing section, an AMR gathering section, and an irregular command processing section. The regular report processing section deals with regularly aggregated meter data and the irregular command processing section can cope well with server (user) commands requested in real time. The experimental results demonstrate that EEBMC is capable of energy efficient operation while maintaining near real-time server command processing ability.
