  Monitoring and automation of the critical infrastructures like the power grid
is improvised by the support of an efficient and secure communication net-work.
Due to the low cost, low power profile, dynamic nature, improved ac-curacy and
scalability, wireless sensor networks (WSN) became an attractive choice for the
Information and Communication Technology (ICT) system of the smart grid.
However, the energy efficiency and security of WSN depends highly on the
network design and routing scheme. In this paper, a WSN based Secure and Energy
Efficient Remote Monitoring Technique (SERMT) is proposed by demonstrating a
WSN based ICT network model for perva-sive monitoring of the generation and
transmission part of the power network in a smart grid system. The performance
of the proposed network model de-signed for a smart grid of IEEE 118-Bus system
coupled with the secure routing technique is tested during cyber-attacks by
means of NS2 and the simulation results indicate that it performs better than
existing smart grid monitoring methods like Lo-ADI [1] with respect to packet
drop count and throughput.
