A multicast routing algorithm for wired/wireless ATM networks

In this paper,we give an algorithm of multicast routing.We take account the handoff probability of the multicast members into the cost function of the multicast routing tree.By doing so,the access points(APs) which serve the mobile members are intended to be designed as the leaves of the multicast tree.After the handoff of an mobile member,we can cut down the AP which served the mobile member before the handoff,we also can cut down the tree branch associating with the AP.So the network resource can be used efficiently.The numeric simulation shows that the algorithm achieves this object.
