This paper is an attempt to further improve the theory of integral sum graph by introducing an integral sum labeling of the lobster tree through sequential labeling method.The paper features the method of identification to prove that a series of multiple lobster trees with the public vertex is integral sum graph.This conclusion not only promotes the type of integral sum graph,but also provides a basis for the theoretical study of the tree.
