Abstract :
In wireless smart metering optimization for energy efficiency is indispensable, because in case of systems without external power supply, battery life is a key factor regarding the usability of the whole system. Sensor networks are less sensitive for delay, this is why aggregation of packets is possible. The aim of this paper is to determine analytically the amount of meter records to aggregate in one packet, regarding the SNR which characterizes the quality of the channel, so that the energy usage is optimal. The introduced formulas, help determining scheduling parameters in wireless smart metering systems. The calculations are presented on a real world scenario and system using GFSK modulation.
