Analyzing the Effects of Black Hole and Gray Hole in Smart Distribution Grid

In Smart Grid, the communication network plays a momentous role. Wired communication adopted to ensure stoutness of the spine for power transmission network but it does not provide any flexibility. Wireless communication for power distribution grid provide more benefits such as high speed links, low cost, easy setup of connections among different devices or appliances and so on. Connecting devices, equipment and appliances through wireless communication is essential for Smart Distribution Grid (SDG). Escalating suitable wireless communication design and its security measures is extremely important for SDG. The Wireless communications intend is planned for SDG on Wireless Mesh Networks (WMNs). Its bidirectional communication and electricity flow facilitate both utilities and customer to forecast, monitor and handle energy usages. Yet, Wireless communications are usually susceptible to security trouble. Being compromised by a malicious node and partially malicious node are not adversary, it would lead to significant damage includes extended power outages and destruction of electrical equipment. Because of malicious node black hole and gray hole will occur in a system. It is important to provide security for SDG against intrusion of a malicious node to offer the availability of effective communication in Smart Grid.
