For a simple graph G with the vertex set V and the edge set E. A labeling f:VUE???{1,2,3,???,k} is called a vertex irregular total k-labeling of G if for any two different vertices x and y in V we have wt(x)???wt(y) where wt(x)=f(x)+???_(y???V(G))??????f(xy)???. The smallest positive integer k such that G has a vertex irregular total k-labeling is called the total vertex irregularity strength of G, denoted by tvs(G). In this paper, we determined the total vertex irregularity strength of Unidentified Flying Object graph, tvs(U_(m,n) ). The result in this paper as follows: tvs (U_(m,n) )=???(3n+1)/2??? for 3???m???3???(n+1)/2???, n???3, and tvs (U_(m,n) )=???(3n+m)/3??? for m>3???(n+1)/2???,n???3.
