Abstract

A reliable and energy-efficient communication infrastructure plays an important role in the success of data collection, transmission and control in smart grid (SG) networks. In order to satisfy the coverage and cost minimization requirements, in this paper, we introduce cognitive radio (CR) into a residential SG network in which the communication load and the available spectrum resource change with the power load in different time periods. To leverage this feature, we propose a spectrum access strategy selection scheme. Moreover, based on the proposed selection scheme, we propose an energy-efficient gateway on-off switching optimization scheme to minimize the energy consumption, while considering the sensing operation and transmission power control of SG nodes. Numerical results reveal that the proposed access strategy selection scheme can increase the average channel capacity of SG nodes considerably, and the proposed gateway on-off switching scheme can balance the tradeoff between the energy consumption and coverage requirement efficiently.
