Abstract
The Wiener index of a connected graph G is defined as W(G)=2_1∑υ,ν∈V(G)dG(υ,ν) with the summation going over all pairs of distinct vertices of G. In this paper, the Wiener type indices of the graph, Mycielskian graph, double graph, sun graph and generalized hierarchical product of two graphs are compunted.
