Self-adjustable trust-based energy efficient routing for smart grid systems

Smart Grid is the trend of next generation electrical power system which makes the power grid intelligent and energy efficient. It requires high level of network reliability to support two-way communication among electrical services, electrical units such as smart meters, and applications. The wireless mesh network infrastructure can provide redundant routes for the smart grid communication network to ensure the network availability. Also due to its high level of flexibility and scalability features that make it become a promising solution for smart grid. However, wireless mesh network infrastructure are vulnerable to some cyber attacks which need to be addressed. In this paper, we proposed and implemented a new trust-based geographical routing protocol, named as Dynamic Trust Elective Geo Routing (DTEGR), which use the trust factor with a dynamic threshold value to generate a trust forwarding list, then it uses distance factor as routing metric to decide the next hop from the trust forwarding list. The simulation studies have confirmed our new DTEGR algorithm able to achieve better routing performance in different network scenarios, and also to achieve high level of reliable data transmission in smart grid communication network.
