碩士 === 國立交通大學 === 資訊科學學系 === 84 === In the mobile communication environment, a multicast service can be presented as a multicast tree. Because mobiles can move between base stations, connection paths will grow longer gradually, and thus this multicast tree may contain some inefficient or redundant paths. Eliminate those inefficient or redundant paths will reduce the bandwidth used and increase the bandwidth utilization. In this thesis, a multicast tree migration scheme is presented. A routing table is designed in each node for finding multicast paths and a path table for recording the multicast tree. The numerical simulations are given to compare the proposed scheme with existing multicast routing algorithms.
