Efficient Network Security Architecture for Heterogeneous Smart Meter Environment

In smart grid communication network, Smart meter (SM) to DCU communication is currently Homogenous in standard. As the trend of SM to DCU communication is approaching towards heterogeneous nature, Intrusion detection will be a challenging task, leading to security issues. A novel Network security scheme is proposed for Heterogeneous SM to DCU environment. Security is established in the network by using and Particle Swarm Optimization (PSO) and Bilinear Diffie-Hellman (BDH) The PSO algorithm helps in finding an access points (AP) best position selection method to forward SM data to DCU through local centralisation method. The BDH gives the best identification scheme is secure against the attacks. The simulation results show an increase of 15% Packet delivery ratio, 7% increase in the end to end delay and 20% increase in throughput is achieved with PSO algorithm for Heterogeneous SM environment with respect to AODV in Homogenous SM enviornment.
