A number of application level multicast protocols have been proposed for core selection and core migration in Mobile Ad Hoc Networks. Core migration is necessary to minimize any disruptions on the transmission of data due to the changes in tree structure and to achieve improvement in the delivery of media streams in multicast group. In this paper, core migration is performed on the varying size network graph model. The nodes within this ad hoc arrangement take on the values of the Edge (We) and node (W) randomly.
