The Wiener index of W(G) is G equal to the sum of distances between all pairs of vertices of G.The Wiener index W, denoted w (wiener 1947) and also known as the path number or wiener number, is a graph index defined by W(G) = ∑_({x,y}∈V(G))▒〖d_G (x,y)〗. . In this paper we investigate wiener index for caterpillar, twig and arrow graph.
