Abstract:
over the last decade, Wireless Sensor Networks (WSNs) have brought radical changes to the means and forms of communication for monitoring and control of a large number of applications including Smart Grid (SG). Traditional energy networks have been modernized to Smart Grids to boost the energy industry in the context of efficient and effective power management, performance, real-time control and information flow using two-way communication between utility provides and end-users. However, integrating two-way communication in smart grid comes at the cost of cyber security vulnerabilities and challenges. In the context of SG, node capture is a severe security threat due to the fact that a compromised node can significantly impact the operations and security of the SG network. In this paper, node compromise attack is explored on Advance Metering Infrastructure (AMI) with smart meters for Neighbor Area Networks (NANs) in star and mesh network topologies. Simulation of node compromise/failure for a SG network, using ZigBee nodes in simulation indicates that a partial mesh topology is more resilient to node capture attacks as compared to star topology. A larger number of nodes are reachable from the control center of the SG in a partial mesh topology compared to that in a star topology.
