Abstract
Let G be a simple and connected graph. The eccentricity connectivity index ECI(G) and the eccentric version of atom-bond connectivity index ABC5(G) of a graph G are and respectively. In this paper, we discuss a new approach to calculate the exact values of ECI of butterfly network, bene network graph and toroidal grid graph. We also find the ABC5(G) indices of these graphs.
