Dynamic Trust Elective Geo Routing to Secure Smart Grid Communication Networks

Abstract

Smart Grid is believed to be the next generation of electrical power system. It integrate the existing electrical power infrastructure with Information Communication Technology (ICT) to achieve two way communication and become smart. A high level of network availability is therefore required to guarantee two-way flows of electricity and information among smart electrical units. The wireless mesh network infrastructure can provide redundant routes for the Smart Grid communications so as to ensure the network availability. However, the wireless connection is vulnerable to cyber-attacks. In this paper, we propose a Fuzzy-Based Energy Aware Trusted Geo-Routing (FEATGR), which can decide the optimal end-to-end path between any source and destination by effectively leveraging the energy consumption, location and trust metrics. The extensive simulation studies have confirmed that FEATGR is capable to achieve the stable and secured routing performance so as to guarantee the high level of network availability for wireless Smart Grid communications.
