Abstract
While existing research has been focussed on supporting handovers of unicast connections, handovers of multicast connections have not been investigated. Conventional multicast leave and join operations always occur over the same path. This is however not true in a Wireless ATM network. Since multicasting supports many applications that require multi-party communications, handovers of multicast connections have become a concern.

Notes
Type of Service refers to services with different delay, throughput, reliability and monetary cost requirements.
Dualcast refers to the ability of a switch to send duplicated packets/cells to two receivers.
DPx is the DP nearest to the old cluster switch, i.e., CLSOLD.
Selecting a CX nearest to DPx will result in shorter resultant paths.
This is possible because the identity of DPx is made known during multicast connection setup and hence each node knows when (i.e., for which connection) it has to function as a DPx.
