Smart grid is an intelligent power network featured by its two-way flows of electricity and information. With an integrated communication infrastructure, smart grid manages the operation of all connected components to provide reliable and sustainable electricity supplies. In smart power grid, an efficient reliable communication architecture plays an important role in improving efficiency, stability and sustainability. The communication infrastructure is multilayered structure that extends the whole smart grid from home area network (HAN) to neighborhood area network (NAN) and wide area networks (WAN). For communication between the subnet works a cognitive radio technology is added which improve spectrum efficiency by utilizing all available spectrum resources in smart grid. This paper focuses on cognitive radio based communication architecture for smart grid. The cognitive radio is mentioned to achieve dynamic spectrum access, interference avoidance, data throughput adaptive and act as a backup wireless communication technique in emergency situations for critical data transmission.
