Trust-based geographical routing for smart grid communication networks

Smart Grid is the trend of next generation power distribution and management network that enable interactive communication and operation between consumers and suppliers, which can achieve intelligent resource management and optimization. The wireless mesh network technology is a promising infrastructure solution to support these smart functionalities, while it has some inherent vulnerabilities and cyber-attack risks to be addressed. As Smart Grid is heavily relying on the communication network, it makes these security concerns more critical. In this paper, we have proposed and implemented a new trust-based geographical routing protocol, named as Trust-based Intelligent Geo Elective Routing (TIGER), which is integrating the distance and trust related factors into a novel routing metric, so as to tackle above problems. The extensive simulation studies confirm that our new TIGER algorithm shows promises for synthesizing trust and distance factors to achieve better routing performance, and also guarantee the reliable communications in wireless mesh infrastructure to avoid attacks in Smart Grid.
