Cognitive Radio for Smart Grid with Security Considerations

In this paper, we investigate how Cognitive Radio as a means of communication can be utilized to serve a smart grid deployment end to end, from a home area network to power generation. We show how Cognitive Radio can be mapped to integrate the possible different communication networks within a smart grid large scale deployment. In addition, various applications in smart grid are defined and discussed showing how Cognitive Radio can be used to fulfill their communication requirements. Moreover, information security issues pertained to the use of Cognitive Radio in a smart grid environment at different levels and layers are discussed and mitigation techniques are suggested. Finally, the well-known Role-Based Access Control (RBAC) is integrated with the Cognitive Radio part of a smart grid communication network to protect against unauthorized access to customer’s data and to the network at large

Sensing-time optimization in cognitive radio enabling Smart Grid

The paper deals with the reduction of the channel outage in a smart grid scenario since it plays a crucial role on the control performance of the Demand/Response Management. A study on a two-way cognitive-based switching procedure is carried out and tools for the optimum sensing-time evaluation are provided. Such evaluation considers a cost function that takes into account both the sensing-accuracy improvement gained by increasing the sensing time and the transmission-capacity degradation induced by sensing-time increasing
