A graph with vertex V and edge E is said to have difference labeling if for an injection f from V to the non-negative integers together with weight function f* on E given by f*(uv)=|f(u)-f(v)| for each edge uv in E. A graph with difference labeling defined on it is called a labeled graph. In this paper we investigate difference labeling on a Sunlet graph Sn, Sparkler graph Pm+n, Shell graph C(n,n-3), Star graph K(1,n), Bistar graph B(m,n), Subdivision of Star graph S(K(1,n)), Subdivision of Wheel graph S(Wn), Triangular Snake graph Tn, Z-Pn graph.
