Graph Theory is the fast growing area of research in Mathematics it has wide applications to several fields - like computer science, social sciences, Science and Technology, etc. Recently, Dominating functions in domination theory playing a key role as they have interesting applications. The theory of domination in graphs introduced by Ore [7] and Berge [2] is an attractive area of research in graph theory in the last three decades.

The concepts of dominating functions are introduced by Hedetniemi [4]. Corona product graphs is a new concept introduced by Frucht and Harary [3] has become an inviting area of research at present. Anantha Lakshmi [1] has introduced new concepts unidomination, upper unidomination, minimal unidominating function of a graph and studied these functions for some standard graphs.

In this paper the authors have studied the concept of unidominating function and upper unidomination number for corona product graph ? K?_n ? W_(1,m) and determined the unidomination number and upper unidomination number for ? K?_n ? W_(1,m). Also the number of unidominating functions of minimum weight is found.
