centrality[1] Degree centrality shows how much a node connected with other nodes. For a node if more the number of direct connections with other nodes more the Degree centrality will be. Greater Degree centrality supports the chances of node to be active. To calculate Degree centrality let N is the set of all nodes in the network ‚ Degree centrality Cd of any node i then where (i‚ j) representing a link between node i and node j. n is the total number of nodes in the network. In figure 1 node C will
