In the third generation of mobile computing environment, the applications that are compatible with small members of group in which joins the multicast session such as internet phone, video conference and networked games are more prevalent. However, since the traditional multicast mechanisms supporting the mobile computing are suitable for large members of group in the multicast session, we need to consider a new mechanism to complement them. Therefore, in this paper we suggest a new multicast model adopted explicit multicast (xcast) which has more gradual deployment with legacy Internet backbone, is cost effective and more scalable and guarantee the QoS in mobile computing.
